Forces inside the Earth put stress on rocks, causing faults where rocks bend and break along surfaces. There are three main types of faults: normal faults where tension pulls rocks apart, reverse faults where rocks are forced up over other rocks, and strike-slip faults where rocks slide past each other horizontally. Earthquakes occur when built-up stress causes rocks along faults to break and release vibrations at the surface.

The document discusses different types of stresses that can occur in the Earth's crust, including tension, compression, and shearing. These stresses can cause rocks to break or bend. Compression occurs when rock is squeezed together, such as when tectonic plates push against each other. Tension pulls and stretches rock. Shearing pushes rock in opposite directions and can cause slipping or changes in shape. Different types of faults, such as reverse faults, strike-slip faults, and normal faults are formed by these stresses. Reverse faults occur when rock is pushed together in compression. Strike-slip faults are formed by shearing as plates slide past each other. Normal faults occur when tension pulls rock apart.

The document summarizes different types of faults and stresses that cause earthquakes. Tension and compression stresses can pull or squeeze rocks, causing faults. Normal faults involve blocks moving apart, while reverse faults involve blocks moving towards each other. Strike-slip faults involve blocks moving horizontally past one another. Folds like anticlines and synclines are caused by compression stresses bending rock layers upward or downward.
Alexus And Sierra Earthquakes
There are different types of stresses that can act on rock and cause it to change shape or volume, including tension, shearing, and compression. Faults occur along plate boundaries when the rock breaks, and can be normal faults when the rock pulls apart, reverse faults when the rock pushes together, or strike-slip faults when the blocks of rock move past each other sideways. The hanging wall is the block of rock above a fault, while the foot wall is below.

There are several types of stresses that can cause earthquakes, including tension, shearing, and compression. Tension occurs when rocks are pulled apart, shearing when rocks slip past each other, and compression when rocks are squeezed together. Normal faults are caused by tension in the earth's crust and form when the hanging wall above the fault is pulled away from the footwall below. Compression stress can squeeze and fold rocks, contributing to the formation of mountains.

Earthquake
A short discussion about faults and the earthquake. Senior High School k-12 Curriculum Guide Compliant. Grade 11 or 12
4.1
Earthquakes occur along faults in the Earth's crust. Stress builds up along faults as the blocks of rock are pushed against one another. When the stress becomes too great, the rocks break free causing the blocks to suddenly move, resulting in an earthquake. Most earthquakes happen along plate boundaries where faults are common due to the movement of tectonic plates. The strength of an earthquake depends on factors like how much stress accumulates before release and the distance the rock slides during the earthquake.
Types of Faults
This document provides information about earthquake terminology and fault lines in the Philippines. It defines key terms like epicenter, hypocenter, fault plane, and fault zone. It also lists the major fault lines in the country, including the Marikina Valley Fault, Western Philippine Fault, and Central Philippine Fault. Different types of faults are described based on the displacement of plates and the orientation of the fault, including dip-slip, strike-slip, and oblique-slip faults.
The earth and changes on it
Weathering breaks down rocks on Earth's surface through processes like sea waves striking cliffs and forming them or glaciers transporting rock particles when melting. Soil erosion removes and moves soil particles from one place to another, such as strong winds in deserts causing exposure and movement of soil.
Landslides (José Antonio Buzón)
This document discusses landslides as a type of natural disaster. It defines a landslide as a geological event where a large mass of land and debris slides down a slope. Landslides can be caused by both natural factors like earthquakes, heavy rainfall, and erosion, as well as human activities that make the ground unstable, such as building on steep slopes. The document describes different types of landslides and their potential consequences, which include buried buildings, cracked ground, and unfortunately sometimes death. It concludes with recommendations for landslide prevention through building design, evacuation planning, and drainage systems.

This document discusses different types of rock deformation including stress, strain, anticlines, synclines, monoclines, normal faults, reverse faults, thrust faults, and strike-slip faults. It also notes that rocks can deform through brittle deformation or ductile formation and that stresses like tensional, compressional, and shear can cause rocks to deform over long periods of time through processes like folding and faulting.
geology field trip
The document summarizes a geology field trip taken by students to study faults, folds, and other geological structures. Some key stops included:
1) Stop 1 featured a "weathering balance" rock formation shaped by a surrounding river.
2) Stop 2 showed examples of anticlines and synclines, as well as normal faults and open fractures.
3) Stop 3 contained many fractures, folds, and normal and reverse faults.
4) Stop 4 also featured normal faults, synclines, and anticlines.
5) Stop 5 observed bitumen seeping to the surface due to a lack of traps for lighter oil deposits. Photographs supported the observations at each location.
Earthquake Basics
Seismology is the study of earthquakes, which occur when stress causes rocks under the Earth's crust to elastically deform until they break, rebounding and snapping back into their original shape. This elastic rebound releases energy in the form of seismic waves, causing the shaking that defines an earthquake. Faults form from tectonic stresses and are breaks in the Earth's crust. The focus is the point within the earth where an earthquake originates, while the epicenter is the point on the surface directly above the focus.

Earthquakes are caused by the sudden release of built-up stress in the Earth's crust that generates seismic waves. There are three main types of faults that cause earthquakes: strike-slip, thrust, and normal. Tectonic plates pushing against each other cause stress that results in either plastic or elastic deformation of rocks; elastic deformation leads to a breaking point where stored energy is suddenly released as seismic waves. The focus is where the slip occurs underground, while the epicenter is on the surface directly above. Modern seismographs can detect and measure seismic waves to provide information about earthquakes.
Landslide
This document defines and describes different types of landslides. It explains that landslides refer to the downward movement of land along steep slopes that can occur suddenly or slowly due to gravity and other factors weakening the stability of the slope. The types of landslides include falls, topples, spreads, creeps, slides, and flows, which are differentiated based on their modes of movement. The document also provides warnings signs of potential landslides and advises evacuating the area if a landslide is deemed imminent.

LANDSLIDES
Landslides are the movement of rock, earth, or debris down a sloped section of land and can be caused by rain, earthquakes, volcanoes or other destabilizing events. They develop when the natural stability of a slope is disturbed and can result in mudslides when water rapidly accumulates in the ground. The impact of landslides can be extensive, including loss of life and destruction of infrastructure, and after Tropical Storm Stan in 2005, landslides caused watersheds in Guatemala to collapse.
Erosion & deposition
This document discusses erosion, deposition, and the agents that cause them. It defines erosion as the movement of rock material from one place to another by various agents like wind, water, waves, gravity, and glaciers. Deposition occurs when eroded sediments are dropped in a new location as the speed of the transporting agent decreases. The main agents of deposition are wind, water, and ice, which drop sediments when they slow down. The key difference is that weathering breaks down rocks, erosion transports materials, and deposition drops the materials in a new place.
Folding and faulting1
Folds and faults are formed by tectonic plate movement. There are six types of folds - anticline, syncline, tight fold, overfold, recumbent fold, and nappe fold. Folds occur when plates are compressed, causing the earth's crust to bend upwards or downwards. There are also five types of faults - normal, reverse, tear, rift valley, and horst faults. Faults happen when the pressure between plates is too great, fracturing the earth's crust. Folds and faults shape the earth's surface over time, creating geographic features like mountains and valleys.
Landslides
A landslide is the movement of rock, debris, or earth down a slope, which can be caused by geological, morphological, physical, or anthropogenic factors. Major types of landslides include debris flows, earth flows, debris avalanches, rock falls, and topples. Landslides frequently occur in Chittagong, Chittagong Hill Tracts, and northeastern Sylhet in Bangladesh due to the unstable soil structure. Mitigation approaches include restricting development in prone areas, monitoring systems, and engineering investigations to define hazard levels.

Rock under Stress Honey pearl.pptx
Rocks undergo deformation and change shape when under stress. There are three main types of stress: tensional stress pulls rocks apart, compressional stress pushes rocks together causing folding or fracturing, and shear stress causes sliding between masses of rock. Geologic structures like faults and folds form in response to these stresses. Faults occur when rocks crack under stress, forming normal, reverse, or strike-slip faults. Folds form when rocks experience compression and bend plastically into anticlines and synclines.
GEOHAZARDS03 - Earthquakes Causes and Measurements.pdf
This document discusses earthquakes, their causes, and how they are measured. It begins by explaining that most earthquakes occur along faults in the earth's crust where tectonic forces cause deformation. It then describes how rocks deform under stress, the different types of stresses that can occur, and how materials respond as either brittle or ductile. Evidence of past deformation is discussed, including how the orientation of inclined rock layers is defined and measured. The document concludes by describing the different types of faults like normal, reverse, strike-slip and transform faults, and explains that earthquakes are caused by a sudden release of elastic strain energy built up along fault zones.
Deformation of Crust
The document discusses the deformation of rock crust through various tectonic processes. It defines deformation as the process by which crust is deformed along plate margins, producing geologic structures like folds, faults, joints and foliation. It describes how different rock types deform under stress through either ductile or brittle deformation. The key types of deformation discussed are folding, where layers of rock are bent, and faulting, where connected blocks of rock are displaced along a fracture plane. Common fold types include anticlines, synclines and monoclines. Fault types include normal, reverse, strike-slip and oblique-slip faults.
Stress in the earth’s crust
This document discusses different types of stresses that cause rock deformation, including confining stress, compression stress, tension stress, and shear stress. It also describes different types of resulting rock features such as folds, fractures, faults, and mountains. Specifically, it compares three types of folds - monoclines, anticlines, and synclines. It also differentiates between three main types of plate boundaries: divergent boundaries which cause tension stress and normal faults, convergent boundaries which cause compression stress and reverse faults, and transform boundaries which cause shear stress and strike-slip faults. Mountains can form at convergent plate boundaries through folding and faulting of rocks.
Faults
Faults occur along planes of weakness in the Earth's crust where displacement has taken place due to tectonic forces. There are three main types of faults - normal faults caused by tension, reverse faults caused by compression, and strike-slip faults caused by horizontal shear. Faults lead to different types of mountain formation, such as folded mountains from crustal compression, fault-block mountains from vertical movement along fault planes, and volcanic mountains from magma erupting at divergent boundaries.
STRESSES, FOLDS AND FAULTS.pptx
This document defines key concepts in structural geology including stress, folds, and faults. It describes three main types of stress - tension, compression, and shear - and how they result in rock deformation. Folds form from compressional stresses and include anticlines, synclines, and monoclines. Faults are fractures in the crust where movement has occurred, and there are three main types - normal faults in areas of tension, reverse faults under compression, and strike-slip faults caused by shearing stresses.
STRESSES, FOLDS AND FAULTS.pptx
The results of stress are folding and faulting. When a rock has stress put on it and does not break it is called folding. Folds appear as wave-like structures in rock layers. Some folds are small and can be seen in individual rocks and some folds are huge and can only be seen from the air.
Impact of Tectonics on Landscapes
Tectonic activity shapes landscapes through various volcanic and non-volcanic processes. Volcanic landforms include extrusive features like volcanic cones and lava plateaus formed by eruptions, and intrusive features such as batholiths, stocks, and dikes formed by underground magma intrusions. Non-volcanic landforms are shaped by earthquakes, faulting, and folding which produce structures like rift valleys, faults, and fold belts that influence topography and coastal geography. The interplay between tectonic forces and erosion over time exposes and modifies these landforms at and below the Earth's surface.
Movement Of The Earths Crust
The document discusses various types of forces that cause stress and deformation in Earth's crust, including compression, tension, shearing, fracturing, and faulting. It describes how different types of faults like normal faults, reverse faults, thrust faults, and strike-slip faults lead to movement of crustal blocks and formation of landforms. It also explains how folding of rock layers contributes to mountain building and discusses how plate tectonics shapes Earth's surface over millions of years.

I hope you can get more ideas on my presentation. This my first report as a education student at HOLY CROSS COLLEGE
Movement Of The Earth’S Crust
The document discusses the movement and deformation of Earth's crust caused by stress from forces pushing and pulling on it. There are different types of stress including compression, tension, shearing, and fracture which cause the crust to break, tilt, fold, or move along faults. Over millions of years, the movement of faults and folding of rocks can build up mountains and other landforms as tectonic plates interact.
Earthquakes revised
Faults form when stresses in the Earth's crust cause rocks to break along fractures. There are three main types of faults: normal faults form when tension pulls rocks apart, reverse faults form when compression squeezes rocks together, and strike-slip faults form when shear forces cause rocks to slide past one another. Most earthquakes occur when built-up stresses are suddenly released as the rocks move along fault surfaces. Earthquake waves travel through the Earth, with P-waves and S-waves causing the ground to shake and damage structures. The resulting shaking can also trigger other hazardous events like tsunamis and liquefaction.
Types faults make earth quake
Normal faults occur when rocks pull apart, causing the rock on one side of the fault to move down relative to the other side. Reverse faults occur when rocks are pushed together, causing the rock on one side to move up. Transform faults cause horizontal movement between blocks of rock on either side. Oblique faults involve a combination of these movements. Faults represent zones of weakness where future earthquakes and surface rupturing are most likely to occur. Infrastructure like buildings and transportation corridors in fault zones faces damage during seismic activity.

Fault
The document discusses different types of faults including normal faults, thrust faults, strike-slip faults, transform faults, and oblique-slip faults. It provides examples of each type of fault and explains the forces and motions that cause each one. Faults form when stress in the earth's crust exceeds the strength of rocks, causing fractures. The movement of tectonic plates applies stress that can result in earthquakes at fault boundaries.
Earth Science 4.4 : Deforming the Earth's Crust
1) Rocks can deform through folding or faulting when subjected to compression or tension stress from tectonic plate movement. There are three main types of folds - anticlines, synclines, and monoclines - and three main types of faults - normal, reverse, and strike-slip.
2) Mountains form through various processes including folding of rock layers, faulting that drops crustal blocks, and volcanic eruption of magma at the surface.
3) Vertical movement of the crust involves either uplift, where areas rise to higher elevations, or subsidence, where areas sink to lower elevations. Uplift can occur through rebound as crust rebounds after being compressed. Subs
DEFORMATION OF THE CRUST.pptx
Deformation of the crust occurs along tectonic plate margins and produces geologic structures like folds and faults. Folds form as bent layers of rock in response to compressional forces, and the main types are anticlines, synclines, and monoclines. Faults form when stresses exceed a rock's strength, causing fractures. The main types of faults are normal, reverse, strike-slip, and oblique-slip faults. Evidence for seafloor spreading includes drilling samples from the ocean floor that show the oldest rocks farthest from mid-ocean ridges and the youngest rocks closest.

Biology 26.1
This document defines key terms related to the animal kingdom, including invertebrates, vertebrates, feedback inhibition, blastula, protostomes, deuterostomes, radial symmetry, bilateral symmetry, and more. It describes animals as multicellular, eukaryotic heterotrophs and outlines their essential functions of feeding, respiration, circulation, excretion, response, movement, and reproduction. Complex animals are noted to have high cell specialization, internal organization, bilateral symmetry, a head with sense organs, and a body cavity.
Biology 26.2
Sponges contain specialized cells like choanocytes that use flagella to move water through the sponge for feeding, respiration, circulation, and excretion. They have structures like spicules made of calcium carbonate or silica that form their skeleton, and archaeocytes that produce these spicules. Sponges reproduce through internal fertilization and larval stages, and some can form protective gemmules during unfavorable conditions.
Biology 22.5
Angiosperms are flowering plants that reproduce sexually through flowers. Flowers contain ovaries that surround and protect seeds. Angiosperms are divided into monocots and dicots based on whether their seeds have one cotyledon (monocot) or two cotyledons (dicot). Flowering plants can also be annuals, biennials, or perennials depending on whether their life cycle is one, two, or more than two years.

The document discusses Precambrian time from 4.56 billion years ago until the Cambrian period over 4 billion years later. It describes shields as flat expanses of ancient metamorphic rock within continental interiors. Stromatolites are layered mounds formed from algae trapping sediment and calcium carbonate. Earth's original atmosphere lacked oxygen but primitive organisms evolved photosynthesis which began releasing oxygen into the atmosphere around 2.5 billion years ago.
Earth science 13.4
The Cenozoic Era saw the rise of mammals as the dominant land animal, replacing reptiles. Flowering plants known as angiosperms also became the dominant land plant over gymnosperms. Major geological events like mountain building, volcanism, and earthquakes occurred in western regions due to plate tectonics during this era. Mammals were better adapted than reptiles for more active lifestyles through bearing live young and maintaining steady body temperatures.
Earth science 13.2
The Paleozoic Era saw an explosion of life, as the continents of Gondwana and Laurasia formed most of the southern and northern portions of the supercontinent Pangea. During the Cambrian, Ordovician, and Silurian periods, life was restricted to the seas surrounding Gondwana, which contained the continents of present-day South America, Africa, Australia, Antarctica, and parts of Asia. By the end of the Paleozoic Era, around 400 million years ago, all continents had fused into the single landmass of Pangea, and plants first began moving from waterside habitats onto land.
Earth science 13.3
The Mesozoic era was the Age of Reptiles, where reptiles like dinosaurs quickly became the dominant land animals due to developing shelled eggs. Gymnosperms also dominated as the prominent plant during this time. A major geological event was the breakup of the supercontinent Pangea. Many reptile groups went extinct at the end of the Mesozoic era.

Continental drift is the hypothesis that the continents were once joined together and have since drifted apart. Originally proposed by Wegener, it suggests the continents were part of a supercontinent called Pangaea approximately 200 million years ago that has since broken apart, moving the landmasses into their current positions. Fossil and rock evidence support this idea, including matching fossil organisms and mountain ranges found on separate continents today that indicate the continents were once joined.

This document discusses seismograms and the different types of seismic waves that are recorded, including P waves, S waves, and surface waves. It explains that seismograms amplify and electronically record ground motion from earthquakes, allowing scientists to determine the epicenter location using travel time graphs from multiple seismographs. The document also covers historical intensity and magnitude scales used to describe earthquake size and introduces moment magnitude as the most widely used scale today because it estimates the energy released.
Biology 28 2 groups of arthropods
This document defines and describes key anatomical terms used to classify groups of arthropods. It discusses the cephalothorax, thorax, and abdomen found in crustaceans, as well as specific structures like the carapace, mandibles, chelipeds, swimmerets, chelicerae, pedipalps, and spinnerets. It concludes with three key concepts: arthropods are classified by body segments and appendages, especially mouthparts; crustaceans typically have two antennae, two or three body sections, and mandibles; and chelicerates have chelicerae mouthparts and two body sections, with nearly all having four pairs of walking legs.
Biology 2.4
Chemical reactions involve reactants being converted into products through breaking and forming chemical bonds, requiring a minimum amount of energy called the activation energy. Catalysts like enzymes speed up reactions by lowering this activation energy, with enzymes being protein catalysts that facilitate substrate reactions within cells.

This document discusses radiometric dating and how it is used to determine the absolute ages of rocks and minerals. It explains key concepts such as radioactivity, half-life, and how comparing ratios of radioactive isotopes like carbon-14 and carbon-12 can be used to calculate radiocarbon dates for samples. Radiometric dating relies on the fact that radioactive isotopes decay at a constant rate and comparing the amounts of parent and daughter isotopes allows the age of a sample to be estimated.

Wind shapes landscapes through processes like deflation, desert pavement formation, and loess and dune deposition. Deflation is the lifting and removal of loose material by wind. Desert pavement is a layer of coarse pebbles created when wind removes finer material. Loess deposits are windblown silt deposits that form blanket-like layers, while dunes are ridges of wind-deposited sand that can vary in shape depending on wind and vegetation factors.
Earth science 7.2
Much of the weathered debris in deserts comes from mechanical weathering like alluvial fans formed where stream slopes abruptly decrease. While chemical weathering is less common, over long periods clays and thin soils can form. Desert streams are ephemeral, only flowing after rain, and often drying up before reaching oceans due to evaporation and soil infiltration. Most desert erosion comes from running water, though wind also erodes deserts, water does the most erosional work.
Earth science 7.1
Glaciers are large masses of ice that originate on land from compacted snow and move due to gravity. During an ice age, large ice sheets form on continents and flow outward, carving U-shaped valleys and depositing unsorted sediment called till. Valley glaciers are smaller glaciers confined to mountain valleys that flow due to plastic deformation and basal sliding between the ice and bedrock.
Earth science 6.3
Groundwater exists below the surface in the saturated zone where all spaces between rock and sediment are filled with water. The water table marks the top of this zone, and groundwater moves slowly through porous and permeable materials. Springs form where the water table intersects the surface, and overuse or contamination can threaten groundwater supplies in some areas. Karst regions have irregular terrain with sinkholes caused by erosion of soluble rock by groundwater in caverns below the water table.

This document defines key terms related to streams and their processes, including bed load, capacity, alluvium, delta, natural levee, floodplain, flood, drainage basin, divide. It also describes concepts such as how streams erode and deposit sediment according to flow velocities, and how flooding occurs and can be mitigated. The overall work of streams is to shape the landscape through erosion, transportation, and deposition of sediment within drainage basins.

The document discusses key concepts about running water and the water cycle. It defines terms like infiltration, transpiration, gradient, stream channel, discharge, tributary, base level, and meander. It explains that water constantly circulates among the oceans, atmosphere, geosphere, and biosphere in the water cycle. Balance in the cycle means annual precipitation equals evaporation globally. A stream's ability to erode and transport materials depends on its velocity, while gradient decreases and discharge increases from headwaters to the mouth.
