Geomorphic Processes
The document discusses three geomorphic processes - weathering, erosion, and mass movement - that slowly change the shape and appearance of landscapes over time. It defines each process, with weathering being the breakdown of rock in place, erosion being the transport of rock fragments by agents like rivers and wind, and mass movement being the downhill movement of weathered rock under gravity. It then asks questions about which photos would illustrate each process and which type of weathering would be most common in different climates.
Succession and Cycles
Ecological succession is the process by which communities of plants and animals gradually replace each other over time in a predictable sequence. Primary succession occurs on new surfaces without soil, being initially colonized by hardy pioneer species like lichens. Secondary succession follows a disturbance to an existing community that does not remove the soil. Factors like seed availability, weather, site conditions, and species interactions influence the progression of succession.
Field assignment part 1-2
The document discusses several types of rocks and geological concepts:
- Blueschist, a metamorphic rock formed under high pressure and relatively cool temperatures in subduction zones.
- Igneous rocks such as granite and gabbro found in San Luis Obispo, formed from intrusive and extrusive processes. Extrusive scoria is also mentioned.
- Sandstone, a sedimentary rock found in Poly Canyon consisting of cemented quartz and sand.
- The San Andreas Fault as an example of a transform fault still actively moving plates.
- Examples of mechanical and chemical weathering processes.
- Evidence of mass wasting and erosion seen in Yosemite National Park streams and waterfalls.
Destructive forces
Erosion, weathering, earthquakes, volcanoes, and the impact of organisms are examples of destructive forces that break down the Earth's surface over time. Erosion is the movement of sediments and soil by forces like wind, water, ice and gravity. Weathering breaks down rocks at or near the Earth's surface through chemical processes like rusting or carbonation, or mechanical processes like abrasion or frost cracking. These destructive forces gradually change the appearance of the Earth's surface features.
Exogenic processes
Exogenic processes originate externally to the Earth's surface and include weathering, erosion, mass wasting, and deposition. Weathering is the breakdown of rocks at the Earth's surface by temperature, rainfall, frost and other environmental factors. Erosion is the transport of weathered rock and sediment by forces like water, wind, glaciers and gravity. Mass wasting is the downward movement of rock and sediment on slopes due to gravity. Deposition occurs as eroded sediments are deposited in a new location through wind, water or other transport processes. Exogenic processes play an important role in shaping the Earth's surface and creating different landforms and landscapes.
Destructive & constructive forces of nature
My son had to do another powerpoint in science class in 5th grade on Destructive & Constructive forces of nature. I helped him with this one and also shared it with my 5th grade students at the time. Students using technology.
Constructive forces
Constructive forces build up and change the Earth's surface. They include deposition by water, wind or ice which forms features like deltas and sand dunes, as well as earthquakes, volcanoes, and faults. Deposition is the dropping of sediment that builds new land, deltas form at river mouths, earthquakes cause vibrations along faults, volcanoes erupt lava and ash to change mountain tops, and faults are fractures where earthquakes occur.
Physical and chemical weathering 11
Weathering is the physical and chemical breakdown of rocks at Earth's surface. It involves interactions between the atmosphere, lithosphere, and hydrosphere. Weathering occurs through both physical and chemical processes. Physical weathering breaks rocks into smaller pieces through forces like frost action, plant growth, and abrasion by water, wind, or glacial ice. Chemical weathering alters the composition of rocks through reactions with oxygen, water, carbon dioxide, and other agents. The rate of weathering depends on climate, mineral composition, and particle size and shape. Weathering produces sediments and soils, including residual soils formed from local bedrock and transported soils with non-local materials.

Ch 10 ppt
Ecological restoration involves facilitating natural succession to help an ecosystem recover from human disturbance. There are two types of succession - primary succession establishes ecosystems in areas with no prior ecosystem, like retreating glaciers, while secondary succession reestablishes ecosystems following disturbances like fires. Restoration is difficult for lands that have lost organic matter or been subjected to overuse, and there does not appear to be a permanent climax state, as gradual loss of nutrients occurs even in mature ecosystems.
Exogenic Process
This document discusses various earth processes including weathering, mass wasting, and soil erosion. It defines weathering as the breakdown of rocks near the earth's surface due to elements like temperature, rainfall, and frost. Weathering occurs through physical processes like exfoliation or chemical processes like oxidation. Mass wasting is the downward movement of rock and soil under gravity, and includes different types of movement like falls, slides, and flows. Soil erosion is the removal of soil faster than its replacement, and can occur through various agents like wind, water, or human activities.

Weathering and erosion shape the Earth's surface over time. Weathering is the breakdown of rocks into smaller pieces through physical, biological, and chemical processes. Physical weathering breaks rocks through forces like earthquakes, while biological weathering occurs as plants and microbes grow and dissolve minerals. Chemical weathering changes the properties of rocks through exposure to acids. Erosion is the movement of weathered rocks and soil by forces like water, wind, and ice. Both weathering and erosion continuously alter the landscape through natural cycles.
Natural & Cultural Landscape
The document defines key terms related to natural and cultural landscapes. It describes natural landscapes as consisting of relief, climate, soils, and vegetation interacting as a system. Cultural landscapes are defined as areas where human activities and modifications have influenced the natural landscape through land use, transport features, population and settlement. Interactions between natural elements and influences of natural features on cultural landscapes are also discussed.
Weathering and Erosion Slideshow
This document discusses different types of weathering and erosion processes including exfoliation, carbonic acid, abrasion, chemical weathering, physical weathering, horizons, and humus. Examples are provided for each process to illustrate how weathering breaks down rocks and erosion transports the eroded material, forming soil horizons and humus layers over time.
Geomorphic process
This document discusses various geomorphic processes including endogenic processes like diastrophism and volcanism as well as exogenic processes like weathering, mass movement, erosion, and deposition. It provides details on different types of weathering such as mechanical, chemical, and biological weathering. The significance of weathering in forming soils and changing landforms is also mentioned. The document also discusses mass movement processes like creep, flow, sliding, and falling and the factors that influence their occurrence on slopes.
Weathering and Erosion
Rocks vary in size, shape, and texture due to weathering and erosion over hundreds of years. Weathering breaks rocks into smaller pieces through mechanical and chemical processes. Mechanical weathering is caused by forces like water, wind, ice, and plants. Chemical weathering occurs when acids from water and carbon dioxide dissolve minerals. Erosion then transports these sediment particles to new locations through agents like wind, water, and animals. This constant weathering and erosion gradually reshapes the landscape over time.
Weathering and soil formation
This document discusses weathering and soil formation. It describes two types of weathering - mechanical and chemical. Mechanical weathering breaks rocks into smaller pieces without changing their chemical composition, while chemical weathering alters the rocks' chemical makeup. Weathering occurs due to factors like temperature changes, frost action, abrasion, and acids. Over time, weathering breaks rocks down into soil. Soil provides nutrients for plants and animals and is important for life. The document also examines different types of soil like residual and transported soil and how soil composition varies by location.
ROCKSEARTHSCIENCE
The document discusses the three main rock types - igneous, sedimentary, and metamorphic rocks. It describes the rock cycle which shows how the different rock types are interrelated through geological processes. Igneous rocks form from the cooling of magma, either below ground (intrusive) or on the surface (extrusive). Sedimentary rocks form through the weathering of existing rocks, erosion and deposition of sediments, and compaction and cementation over time. Metamorphic rocks form from the alteration of existing rocks deep underground under high pressures and temperatures.
Fundamentals of soil science
The document discusses fundamentals of soil science. It defines key terms like pedosphere, pedon, and polypedon. The pedosphere is the outermost layer of the Earth composed of soil and subject to soil formation processes. A pedon is the smallest volume of soil recognized as an individual soil. A polypedon is a contiguous group of similar pedons that together define a soil individual. The document also summarizes the six key functions of soil and outlines the two branches of soil science - pedology and edaphology.
Soil
This document discusses soil, including its composition, formation processes, and classification. Soil forms through weathering of parent materials and is influenced by climate, topography, biological factors, and time. Key processes in soil formation include leaching, eluviation, illuviation, podsolisation, and gleying. Soil taxonomy classifies soils into orders, suborders, great groups, and subgroups based on properties related to formation factors. Soil provides the medium for plant growth and is a natural resource consisting of minerals, water, air, organic matter, and living organisms.
Geography Chapter 2.4 external forces
Weathering and erosion slowly alter landscapes over time through physical and chemical processes. Weathering breaks rocks into smaller pieces of sediment through mechanical and chemical breakdown without changing the rock's composition. Erosion then transports this weathered material like sediment, forming new landforms as it is deposited by forces such as wind, water, ice or gravity. These gradual changes to the earth's surface through weathering and erosion impact how humans interact with their environment.

Physical geology is the study of the Earth's materials and processes that shape them. The Earth is divided into internal structure and surface features. Internally, it consists of the crust, mantle, and core. The lithosphere includes the crust and upper mantle broken into tectonic plates. Plate tectonics theory describes the movement of these plates across Earth's surface over time. There are three types of plate boundaries - divergent where plates move apart, convergent where one plate overrides another, and transform where plates slide past one another.

For each rock type, Sara describes examples she found in different locations, provides pictures and her analysis of each rock, and identifies the type of rock based on its characteristics. She believes one igneous rock is feldspar found in a creek bed near Bakersfield. Her metamorphic rocks include possible slate found at Morro Bay beach and quartzite from a creek in Coalinga. The sedimentary rocks are likely sandstone from Pyramid Lake and limestone from caves at Pismo Beach.
Geology
Geology is the study of the physical structure and substance of the Earth. It provides knowledge about construction materials like stones and clay. It also helps understand natural geological processes like erosion that impact civil engineering projects. Geology is important for determining suitable foundations, exploring ground conditions via drilling, and planning major projects like dams, roads and tunnels. The study of geology includes physical geology, petrology, structural geology, and the weathering of rocks. Physical geology examines how the Earth's surface and interior change over time. Petrology studies the origin, composition and structure of different rock types. Structural geology analyzes the three-dimensional distribution of rocks and their deformation history. Weathering breaks down rocks through mechanical and chemical processes.
Geology
A geologist studies the solid and liquid matter that constitutes the Earth, as well as the processes that have shaped it. They approach geology using various sciences. A physical geologist specifically focuses on the materials the Earth is made of and the processes that form them. To become a geologist requires at minimum a bachelor's degree in geology or a related field, with many positions requiring a graduate degree. Geologists work in government agencies, engineering firms, museums, and oil/gas/mining companies. Their typical uniform and tools include hammers, safety goggles, backpacks, and notebooks.

It then discusses the importance and scope of geology for civil engineering, including providing construction materials knowledge, helping with erosion and deposition projects, tunneling and foundations, and reducing engineering costs.
Introduction of engineering geology
This document discusses key aspects of engineering geology and its importance in modern development. It provides examples of how poor subsurface conditions, lack of safety measures, and lack of studies can lead to infrastructure failures. It emphasizes the role of engineering geology in properly studying soil and subsurface conditions before construction to select the best design and safety remedies. Methods discussed include field and laboratory investigations to understand rock quality and recommend appropriate structural support.
What is geology and scope of geology
Geology is the study of the Earth, including its composition, structure, physical properties, history and the processes that shape it. The document outlines several key branches of geology, including economic geology, mining geology, petroleum geology, engineering geology, environmental geology, geochemistry, geomorphology, geophysics, historical geology, hydrogeology, mineralogy, paleontology, petrology, structural geology, sedimentology, stratigraphy and volcanology. Each branch deals with different aspects of the Earth and geological processes. Engineering geology specifically applies geological knowledge to civil engineering projects regarding construction materials, site selection, and safe design and construction.
Structure geology basics and applications
Structural geology is the study of rock deformation and structures caused by tectonic forces within the Earth. Key concepts include strike and dip of geological features, the three main types of faults, and different kinds of folds and joints that form due to compression and tension. Structural geology provides important information for engineering projects, mineral and petroleum exploration, environmental assessments, and understanding earthquake hazards and groundwater flow. Proper interpretation of geological structures relies on understanding principles of stress, strain, and plate tectonics.

Erika Ramos collected different types of rocks from various locations in California for a geology lab assignment. She found igneous rocks with a granite texture in three rivers. Sedimentary rocks showed signs of change and splitting, and felt layered. Metamorphic rocks had a granite-like texture but felt smoother. Ramos located a fault in Mineral Springs near Coalinga, which is part of the San Andreas Fault. She observed chemical and mechanical weathering in different areas and saw mass wasting and erosion events caused by water and wind. Ramos found marine and transitional sedimentary environments in Pismo Beach and three rivers respectively.

Field Assignment 2
This document contains field assignment notes and photos from a geology class. It includes photos and descriptions of:
1) The San Andreas Fault at Parkfield, CA, known for its slow fault creep and small to moderate earthquakes.
2) Examples of weathering processes like oxidation rusting of metal from long water exposure.
3) Mass wasting from gravity-driven cliff erosion and deterioration of rock from wind and water erosion.
4) Continental, marine, and transitional environments illustrated by photos of Sierra Nevada mountains, the Pacific Ocean, and Pismo Beach shoreline respectively.
Geology Field Assignment II
The San Andreas Fault is an 810-mile continental transform fault that forms the tectonic boundary between the Pacific and North American plates in California. It has right-lateral strike-slip motion. Weathering is the breakdown of rocks through atmospheric or biological processes, and can be physical or chemical. Physical weathering breaks down rocks mechanically through temperature changes or pressure, while chemical weathering alters rock compositions through chemical reactions with water or biologically produced chemicals. Mass wasting and erosion are geological processes that move or remove earth materials such as soil and rock downslope or to new locations.
Part 2
This document summarizes a geology student's field and lab assignment. It includes photos taken by the student of various geological features and concepts. The photos show examples of [1] the San Andreas Fault, [2] mechanical and chemical weathering, [3] erosion, mass wasting, and different environments, and [4] concludes with an example of practical geology - the Golden Gate Bridge. Sources consulted are cited.
Field lab part2!!
The document summarizes a student's field lab experience observing the San Andreas Fault in California. It provides examples of different geological features and processes the student documented, including:
1) Mechanical and chemical weathering processes seen in rocks along the fault line.
2) Evidence of mass wasting in the form of landslides caused by slumping.
3) Different sedimentary environments observed, such as continental lakes, marine beaches, and transitional shorelines.
4) Examples of how geology is practically applied.
Field lab assignment Part Two
The document summarizes key details about the San Andreas Fault in California. It is a continental transform fault that runs approximately 810 miles through California. The fault forms the tectonic boundary between the North American and Pacific plates and has a right-lateral horizontal motion. The fault is divided into three segments: the northern, central, and southern segments. Pictures from Yosemite National Park show examples of weathering, erosion, mass wasting, and different sedimentary environments.
Part 2
Two main types of weathering are mechanical and chemical weathering. Mechanical weathering involves physical breakdown of rocks without chemical change, such as from pressure that causes rocks to break apart. Chemical weathering involves chemical changes that alter the composition of rocks, such as acid rain dissolving a brick wall. Examples of erosion include wind and water creating caves in rocks. Glacial erosion is demonstrated by the shaping of Half Dome in Yosemite. Sedimentary environments include continental dunes formed by wind, transitional beaches and shorelines, and marine reefs. Local geology examples provided are the human-made Montecello Dam, the natural rock foundation of the San Matego Bridge, and surface cracks and offsets caused by the
Field assignment part 2
The San Andreas Fault runs nearly the length of California and is classified as a strike-slip fault, causing side-to-side movement between tectonic plates that has resulted in many earthquakes. Chemical and physical weathering change and break down rocks through chemical reactions and plant growth, respectively. Mass wasting such as rockslides transport loose rock and soil downslope due to gravity. Erosion by water widens creeks and rivers over time by carrying away eroded material. Marine, transitional, and continental sedimentary environments deposit sediments from moving water in oceans, shorelines, and streams/rivers. Geology informs practical applications like bridges, canals, and oil extraction.
Geology 1 Lab Assignment part II

All photos were taken by Dana in locations in California and some information was provided by geologist Andy Snyder.
The san joaquin fault
The document summarizes a field/lab assignment completed by Jose Berber where they collected and analyzed different rock samples near Highway 5 in California. Jose describes the geological features of the area including the San Joaquin fault line and analyzes the different rocks collected, identifying some as igneous, sedimentary, and metamorphic based on their crystalline structures and how they were formed. Jose also describes various weathering and erosion events observed in the area and provides examples of human geological uses like a skate park and power plant built atop the local geology.
Geol part 2
The San Andreas Fault is a major right lateral strike slip fault less than an hour from West Hills Campus. During the 1906 San Francisco earthquake, the fault slipped several feet, one of the largest single slips in history. It forms a valley several miles wide centered on a creek bed in Parkfield. Physical and mechanical weathering break rocks through heating and cooling or organisms. Mass wasting is the downward movement of soil and rock under gravity, such as common rock slides. Erosion is the transport of sediments and rocks from one area to another by wind, water, and gravity.
Geology
Rocks form the basis of the Earth's surface and have been present on Earth longer than humans. There are three main types of rocks - sedimentary, metamorphic, and igneous - which are distinguished by their formation process. Sedimentary rocks form from compression of soil and sediments and may contain fossils. Metamorphic rocks form from changes to existing rocks through heat, pressure, and chemical activity. Igneous rocks form from cooling lava or magma, and their grain size depends on the cooling rate at their formation site.
G. glasheen geology final
Yosemite Valley provides examples of various geologic processes. It formed around 10 million years ago as the Sierra Nevada range uplifted, and glaciers later carved out the valleys. On a hike to Upper Yosemite Falls, the author documented different rock types and geologic features. Granite samples showed igneous intrusion, while talus slopes demonstrated mass wasting. Sediment deposition was seen in ice and conglomerate. Frost wedging and erosion illustrated ongoing weathering processes. Practical applications included a bridge utilizing the valley geology.
EROSION & DEPOSITION (teach)
Erosion and deposition are closely related processes where erosion involves the movement of rocks and sediment from one location to another under the forces of water, wind, or ice. Deposition then occurs when these agents carrying sediment slow down and drop their loads in a new location. Water is the primary agent of erosion, carrying sediment downstream as it erodes rocks and soil from higher elevations. As water velocity decreases, such as at the mouth of a river, its sediment load is deposited, potentially forming features like deltas or beaches over time. Wind is also an erosive force, picking up and transporting sediment which is later deposited in locations like sand dunes when winds calm.
Geol3 presentation2 ( continued)
The document discusses different sedimentary environments and provides examples of each:
1) An example of erosion on a small scale showing harder surfaces preventing erosion underneath.
2) The marine environment being the continental shelf underwater, as seen in a photo of the Pacific Ocean.
3) A photo example of a continental environment with mountains collecting snow that melts into channels and deposits sediments downstream.
4) Transitional environments like coastlines and beaches seen in a photo of the author at a beach town as tides change the coastline exposure.
Geo 1 field assignment
The document summarizes Juan Tiscareño's field assignment where he searched for and identified different types of rocks near Firebaugh, CA. He found igneous, sedimentary, and metamorphic rocks. He also observed examples of geological processes like the San Andreas Fault, chemical and mechanical weathering, mass wasting, and erosion. Juan notes two examples of geological uses - a skate park that provides exercise and power plants that generate energy from the geological resources in the area.

Francisco Rosas Manzo Field Lab Assingment
This document summarizes a geology student's field assignment collecting and identifying rock samples in Kings Canyon National Park. The student identified samples of granite, basalt, sandstone, conglomerate, and weathered sandstone. They also discussed faults, weathering, mass wasting, erosion, sedimentary environments including continental, marine, and transitional, and the practical uses of geology such as bridges. The student enjoyed the assignment but had difficulty with rock identification from photographs alone.
Geology lab field assignment
This geology lab assignment examines the geology around Lake Tahoe Community College. The student explored areas around Lake Tahoe like Fallen Leaf Lake, sand pits in South Lake, Twin Peaks, and Topaz Lake in Nevada. Through these observations and additional research, the student found that fault movements and volcanism created the basin and surrounding Sierra Nevada mountains. The assignment involved identifying local rocks, fossils, and lizards. Key findings included evidence of the law of superposition in rock layers and an angular unconformity.
Field study #2
Clayton Ahumada documented geological features observed during family road trips in California. Several photos were taken along Highway 198 near Coalinga and through the Parkfield area, showing examples of the San Andreas Fault, mechanical and chemical weathering, mass wasting, erosion, and continental sedimentary environments. Additional pictures near San Francisco displayed marine and transitional sedimentary environments at the shoreline. One final photo depicted a Parshall flume used to measure irrigation water distribution in the Central Valley.

Geology project part two
- 2. In this section…. In this part of the project we will be looking at a fault, a few weathering processes, mass wasting, erosional events, and different types of sedimentary environments. The last slide will show practical use of geology in the location that I am living in now. Enjoy!
- 3. What is a fault The definition of a fault is a break in a rock mass along which movement has occurred. The most famous or well known fault is the San Andreas Fault in California. Not all faults are as big as this one is though. I was not able to get my own pictures of the fault that I found interesting so the next slides are not my pictures, but it is still some very interesting pictures and information.
- 4. In 1952 there was a 7.7 magnitude earth quake near Bakersfield, Ca. It created the White Wolf fault which starts near Laval road exit on the I-5. It stretches about 34 miles long. This type of fault is a high angle reverse fault. The picture to the left is near bear mountain and is a vertical fracture along the fault. The second picture is of down town Bakersfield. This damage was due to an aftershock almost a month after the original earthquake.
- 5. Weathering Process Weathering is the physical breakdown and chemical alteration of rock at or near Earth’s surface. This is a very important process in Earth’s system. It is very important to us because a lot of the food we eat was freed by the weathering process. The next slide will show two different weathering processes. The first picture of the mountain side is the process of frost wedging. The second picture will be
- 6. The top picture is of mechanical weathering. The specific type is Frost Wedging. This picture was taken when I was traveling the grapevine last winter. The bottom picture is a picture of oxidation. Oxidation is a chemical reaction that occurs when electrons are lost from one element during the reaction.
- 7. Mass Wasting and Erosional Events Mass wasting is the transfer of rock and soil downslope under the influence of gravity. Erosion is the physical removal of material by mobile agents such as water, wind or ice. This is a picture of mass wasting again I got this picture on the grapevine. You can tell by the photo that pressure has made some downward slopes overtime on this hill side.
- 8. Sedimentary environments There are three different types of Sedimentary environments. Continental which are dominated by the erosion and deposition associated with streams. Marine which is divided into shallow marine and deep marine. Then there is Transitional which would be the shoreline.
- 9. This would be a This would be a This last picture transitional continental would be of a marine sedimentary sedimentary sedimentary environment. The environment. They environment. I location of this are mostly believe it would be a picture is the dominated by shallow marine shoreline of Santa streams, which is environment at that. Monica. In the what you are looking This picture was picture you see the at. taken at Morro Bay. Santa Monica Pier. Yes I do love the beach.
- 10. http://blog.photolalia.net/2008/06/east-of-oildale.html Practical use of Geology: Bakersfield This picture I didn’t take but it is of the abundant oil fields in Bakersfield. I took the picture at night because it is so beautiful then, but it didn’t come out very nice. This is a practical use of geology because oil fields are very important to how we live today. The equipment being used is taking oil from the earth so that we can use it in our everyday lives.
