Sedimentary rocks are formed by the deposition of material on the earth's surface or in bodies of water, and make up around 8% of the earth's crust by volume. Intrusive igneous rocks form underground from magma that cools and solidifies within the surrounding country rock, resulting in coarse-grained textures. Metamorphic rocks comprise a large part of the earth's crust and form under high temperatures and pressures, being classified by their textures and mineral assemblages.

Before, the Redwood National Forest was green and healthy with undisturbed trees. The Polar Ice Caps had large chunks of ice that rarely melted. Canaan Lake was a place where people could swim and skate.
After, changes from global warming caused increases in temperature that impacted plants, trees, and animals in the Redwood Forest. The Polar Ice Caps lost much of their ice, melting faster and causing sea levels to rise. Canaan Lake is now almost a swamp, too warm for swimming or skating, overgrown with weeds and pollution where only ducks and swans live. Global warming negatively changed these three environments.
Geology in the Macleay valley
The rocks in the Macleay Valley were formed 250 million years ago at the bottom of a sea during the Permian period. These sedimentary rocks, including mudstone, siltstone, sandstone, conglomerate and limestone can be seen in road cuttings and along the Macleay River. The folding of these layers during the formation of the Great Dividing Range causes them to be at various angles, resulting in frequent landslides during wet weather. Different rock types are also visible including slate, basalt, granite and limestone, which are used for various purposes by humans.

The document summarizes Mormon Rocks and Etiwanda Preserve. Mormon Rocks got their name from Mormon Pioneers who camped there. The rocks were formed by the San Andreas fault lifting sandstone, which was then shaped by wind and rain erosion. The San Andreas fault runs through the area and holes in the Mormon rocks were formed as wind and rain eroded boulders out of the sandstone structure over time. The Etiwanda Preserve was created to protect the local Riversidian Alluvial sage scrub habitat and contains various vegetation like white sage, but development has damaged much of the original habitat.

Eaton Canyon is located in the San Gabriel Mountains in Pasadena, California. The mountains were formed by earthquake activity along the San Gabriel fault. The canyon provides examples of various rock types common to the area, including metamorphic rocks like gneiss and mica schist as well as igneous granite pegmatite rocks. Layers of older metamorphic rocks can be seen below younger layers, following the law of superposition. Erosion from earthquakes and rainfall causes the exposed layers to show signs of nonconformities.

Coral reefs are sea structures made of living organisms called coral polyps that spawn eggs and help the reef gain a stable structure over time. The Great Barrier Reef off the coast of Australia can be seen from space and is home to brain coral, fire coral, fish, jellyfish, and the crown of thorns starfish. People use the Great Barrier Reef for fishing, snorkeling, and scuba diving but also threaten it through overfishing, littering, and illegal logging. Efforts are underway to preserve the reef by reducing threats like the crown of thorns starfish and cleaning up litter.
Soil Erosion along a creek bed
This document discusses soil erosion along creek banks. It provides an overview of the Purga Creek in Queensland, Australia as a case study. The main causes of soil erosion along creek banks are identified as natural processes like floods, as well as human activities like land clearing and cattle grazing. Allowing native plants to grow along creek banks can help mitigate erosion by holding soil with their roots. Planting trees and fencing off cattle are recommended actions to reduce erosion.
Coral reefs
Coral reefs are complex ecosystems located around the equator that are made up of coral skeletons inhabited by many living creatures like fish, crabs, and turtles. While most coral reefs exist in warm tropical waters, the UK has cold water coral reefs off the Rockall Islands that are similar to tropical reefs but contain different types of fish.

Geology of Lake Tahoe Basin - 2015
The Lake Tahoe Basin was formed 2-3 million years ago by geological faulting that uplifted the Carson Range and Sierra Nevada mountains on either side and dropped the land between them to form the basin. Faults beneath the lake are potential earthquake risks. The area was under a shallow sea 400 million years ago, and over 130 million years sedimentary rocks like mudstone, sandstone and limestone formed and were uplifted, forming metamorphic rocks. Today the basin contains forests and meadows home to birds, chipmunks and wildflowers. Glacial features like moraines formed lakes such as Fallen Leaf Lake.

Detailed Trip Report: First Part
7:45 a.m. We departed from Campus.
We drove north on Highway 101. As we continued north through the Highway, we passed through Yachats, a town that is approximately 75 miles. Just on the left past the Adobe Motel was the turn-off to Smelt Sands Beach which was our first stop. ( thatโs all copied)
Stop 1: Smelt Sands Beach.
Smooth and brown rocks are molded together by wet beach sand. The sand is, however, coarse with contents including, quartz, basalt, shell pieces, serpentine and agates. The rock forming the base rock formation is present in the sand signifying the rock is broken down by erosion.
Different rocks are also exposed and are believed to be from the Cenozoic Era. They are featured as part of the Yachats Basalt and are Late Eocene (36-40 million years) in age. These rocks were formed as a result of the cooling of magma from a series of eruptions ( this is all copied from that cheater essay.. not hard to tell see I told youโฆ KEEP This I will alter (Alt and Hyndman 1978).
There is the existence of a Pleistocene terrace where the town of Yachats is built. The terrace was probably formed when the sea level was lower, and its deposit is 10,000 to 1.8 million years old. It cuts into the Yachats basalt sequence (Snavely, 1980). Its present level, which is above, the present sea level, is attributed to either the rise of land due to tectonic activity or dropping of the sea level. It is, however, difficult to know where the uplift of the land is possible in such an active coastline. The Smelt Sands Beach is located to the South of the start of Yaquina formation. A basalt flow is found at this spot. It lies beneath the Pleistocene terrace. This basalt is about 40 million years old. The Pleistocene, on the other hand, is about 1.8 years old. What happened between the formation of the basalt and the Pleistocene is not known yet. However, some researchers speculate that land movement could have occurred which led to dropping of the sea level or rising of the land. The whole town of Yachats has been built on this beach terrace.
Information about the town of Yachats indicates that much is of it occurs in a zone that prone to tsunami if another Cascadia subduction occurs. The part of the town, which is not, in the tsunami zone is found on the hillside. However, this part also risks destruction from the tsunami-causing earthquake. Studies carried out by researchers indicate 50m of beach would retreat in this region should a cascadia subduction occur (Snavely, 1980). This means that the biggest part of the Yachats town would be destroyed considering that most of the premises in the town, which include shops, hotels and residential houses are within a distance of 50m from the water. Plants found in this region include bog anemones and gold-eyed grasses..
Geol3 part 1
David Pilcher collected various rock samples in California to fulfill a geology assignment. He traveled to San Luis Obispo County to study metamorphic rocks formed by the San Andreas Fault. He found hornfels along the coastal mountain ranges. Sedimentary rocks were found along the central coast, including sandstone and conglomerate collected from beaches. Igneous granite samples were easily accessible in the Sierra Nevada foothills near volcanic rock formations resulting from the subduction of tectonic plates millions of years ago. Through field observations and comparisons to online resources, David was able to identify the different rock types and understand how they relate to California's geological history.

4) A rhyolite rock sample found in the author's backyard described as light brown in color and located in a muddy area with cracks.
5) An amphibolite rock
Field Assignment 2
This document contains 6 summaries of geological concepts and locations:
1) The San Andreas Fault runs 810 miles through California and forms the boundary between the Pacific and North American tectonic plates.
2) Morro Rock shows an example of weathering, which is the breakdown of rock through contact with the atmosphere.
3) A photo from Pine Flat Dam shows erosion in the form of a river cliff and exposed tree roots.
4) A cliff seen from Pine Flat Dam is thought to be an example of past mass wasting.
Geog5 Photo J
Gabriel Heimberg documented photos from a geography field trip through California deserts and mountains. The photos showed various landforms like the California Aqueduct, Joshua trees in the desert, a solar power plant, and the SETI satellite dishes. Other photos documented Mormon Rocks by the San Andreas Fault, cinder cones at Cinder Hill, petroglyphs and house rings left by Native Americans, glaciated valleys, and Mono Lake with its receding shoreline and tufa formations. The photos were accompanied by explanations of the geographic features and processes that formed the landscapes.

The document summarizes the geology of the San Joaquin Valley in California. It describes how the valley formed 65 million years ago between two mountain ranges. Sediment from the Sierra Nevada filled the basin. The document also discusses the evolution of pill bugs from sea creatures with gills to land-dwelling crustaceans. Spider plants are described as having adapted from South African origins to survive drought conditions through a tuberous root system. Samples of igneous granite, metamorphic slate, and sedimentary shale rocks found in Fresno are presented along with their identifying characteristics.
Lab field assignment
The document describes a student's field and lab assignment where they identified and described various rocks and geological features they encountered. It includes descriptions of igneous, metamorphic, and sedimentary rocks the student found on hiking trips. The student also provides pictures showing examples of geological structures and processes like faults, mass wasting, weathering, sedimentary environments, erosion events, and how geology is applied in infrastructure.
Rocks geol 1
This document discusses several key topics in geology including metamorphic rocks like gneiss and quartz, sedimentary rocks like sandstone, igneous rocks like granite and basalt, the San Andreas Fault, weathering processes, mass wasting and erosion events, sedimentary environments, and practical uses of geology like bridges. It provides descriptions and examples of different rock types found in various locations and how they are formed through metamorphic, sedimentary, and igneous processes. Faults, weathering, erosion, and sedimentary environments are also summarized.
Field trip[1]
Mormon Rocks are sandstone rock formations named for Mormon pioneers who would camp near them after crossing the Mojave Desert. They were created by movements along the San Andreas Fault. The San Andreas Fault is a major fracture zone in California's crust that has caused many earthquakes as the tectonic plates move along it. Joshua Trees were probably named by Mormons during their 1851 trek from Utah to Southern California.
Field
The document describes 5 rock samples collected by the author. The first sample is granite found in Sequoia National Park estimated to be 20,000 years old. The second sample is also granite from Sequoia National Park, which is the author's favorite. The third sample is marble collected from Morro Bay, a metamorphic rock. The fourth sample is basalt from the author's yard. The fifth sample is a sedimentary rock found on Pismo Beach.
