How does stress in the crust change Earth's surface?
tension, compression, and shearing work over millions of years to change the shape and volume of rock. These types of stress cause the crust to bend, stretch, break, tilt, fold and slide.
Where are faults usually found and why do they form?
Most faults occur along plate boundaries and occur when the forces of plate motion push or pull the crust so much that the crust breaks.
What land features result from the forces of plate movement?
anticlines, synclines, folded mountains, fault block mountains and plateaus.
Name 5 kinds of landforms caused by plate movement
mountains, volcanos, valleys, ridges, and trenches
How does the energy of an earthquake travel through Earth
with seismic waves
what are the scales used to measure the strength of an earthquake?
richter scale, mercalli scale, and moment magnitude scale
How do scientists locate the epicenter of an earthquake?
They use seismic waves. Scientists measure the distance between the arrival times of the P waves and S waves. The farther away an earthquake is, the greater the time between the arrival of the P waves and the s waves. They draw circles of the seismographs. The radius of each circle is the distance from that seismogarph to the epicenter.
How do the different types of seismic waves travel through the interior and surface of the Earth?
P waves compress and expand the ground like an accordion.
S waves shake the ground back and forth. S waves can't travel through liquids.
Surface waves can make the ground roll like ocean waves and shake buildings from size to size.
