On a map ,they are concentrated along the edges of the Pacific Ocean where many volcanoes are also located . Earth's crust experiences a lot of stress because the plates are coliding seprating or grinding past each other. The movement and interactions of the plates cause the crust to break into different types of faults]]> 2017-04-06 13:16:51 UTC https://padlet.com/michael_culbertson/6kq95s2pekxs/wish/165127974 michael_culbertson https://padlet.com/michael_culbertson/6kq95s2pekxs/wish/165130192

Stress from the stretching makes the rock thinner. The tension creates faults. because the crust is thin near these boundaries , earthquakes tend to be shallow. A mid-ocean ridge is an example of a divergent boundaries where earthquakes occur. ]]> 2017-04-06 13:24:31 UTC https://padlet.com/michael_culbertson/6kq95s2pekxs/wish/165130556 michael_culbertson https://padlet.com/michael_culbertson/6kq95s2pekxs/wish/165132288 Two plates collide causing rock to be squeezed. This stress is called compression. These faults are called reverse faults. Rock are thrust over one another. Two things can happen at reverse faults. First the plates may crumble up to form mountains. Second one plate can sub duct or sink underneath the other into the mantle. Earthquakes on or near these faults are deep and tend to be very strong.]]> 2017-04-06 13:30:04 UTC https://padlet.com/michael_culbertson/6kq95s2pekxs/wish/165132288 michael_culbertson https://padlet.com/michael_culbertson/6kq95s2pekxs/wish/165134814 At these boundaries, plates slide past each other horizontally. Stress at these boundaries is caused by pushing different parts of the body in opposite directions (shear stress) As the rock move on both sides of the fault they get broken as they grind past one another. strike-slip faults are common at these boundaries. They are also shallow like divergent]]> 2017-04-06 13:38:06 UTC https://padlet.com/michael_culbertson/6kq95s2pekxs/wish/165134814 michael_culbertson https://padlet.com/michael_culbertson/6kq95s2pekxs/wish/165138077 Danger to people and structures
The seismic waves are released from the epicenter of the earthquake with the strongest being at the epicenter and the waves are weaker the further from the epicenter. Structures will move and may not be able to withstand the movement and collapse. Most injuries occur from these. Other factors are fires, gas leaks, floods, polluted water.
Tsunami
A tsunami occurs when there is an earthquake under the ocean.This causes a lot of water to be displaced creating extremely long waves that can across the ocean at speed of 800 km/hr. The waves travel outward like the seismic waves from a land earthquake. Waves increase as they reach the shore and can be as high as 30m. They can smash and destroy anything in their path and many living things are lost from drowning]]> 2017-04-06 13:46:50 UTC https://padlet.com/michael_culbertson/6kq95s2pekxs/wish/165138077 michael_culbertson https://padlet.com/michael_culbertson/6kq95s2pekxs/wish/165662806 Study Guide
1. Know how to spell all vocab words
2. explain the relationship between the earthquakes focus and epicenter the closer to you are to the epicenter, the stronger the effects are
A: the epicenter is right above the focus
3.explain the relationship between plate boundaries and earthquake locations.
A: Earthquakes are a result of plate tectonics. Hint pacific ocean
4.Divergent: pull apart, tension, reverse faults
Convergent: push together, compression, reverse faults, strong earthquakes
Transformant: slide horizontally strike-slip faults, shear stress
5. What is the relationship between an earthquake and a tsunami
A: Tsunamis occur from earthquakes that happen under the ocean floor]]> 2017-04-10 13:22:16 UTC https://padlet.com/michael_culbertson/6kq95s2pekxs/wish/165662806 michael_culbertson https://padlet.com/michael_culbertson/6kq95s2pekxs/wish/165670248
