Earthquakes Section One and Two Key Terms

Section One:Seismology-The study of earthquakes.

Deformation-the bending, tilting, and breaking of the earth's crust;the change in the shape of rockin response to stress.

Elastic Rebound-the sudden return of elastically deformedrock to its undeformed shape.

Seismic Wave-a wave of energy that travels through the earth,away from an earthquake in all directions.

P Wave-a seismic wave that causes particles of rock to move in a back-and-forth direction.

S Wave-a seismic wave that causes particles of rock to move in a side-to-sidedirection.

Section Two:Seismograph-an instrument that records vibrations in the ground and determines the location and strength of an earthquake.

Seismogram-a tracing of an earthquake motion that is created by a seismograph.

Epicenter-the point on earth's surface directly above an earrhquake's starting point, or focus.

Focus-the point along a a fault at which the first motion of an earthuake occurs.

Section Three: Gap Hypothesis-a hypothesis that is based on the idea that a major earthquake is more likely to occur along the part of an active fault where no earthquakes have occurred for a certain period of time.

Seismic Gap-an area along a fault where relatively few earthquakes have occurred recently but where strong earthquakes have occurred in the past.

'''Where Do Earthquakes Occur? And What causes them.''' Most earthquakes occur near the edges of the tectonic platers are. ectonic plates are giant pieces of the earths outermost layer.These tectonic plates move in many different directions.Two plates can push or pull against each other.They can slow slip past each other. As a result of these movement, numerous features called faults exist in the earth's crust.A fault is a break in the earth's crust.

Figures On P.132 & 133 and Table one It explains the different types of movements an earthquake will make like how: transform motion occurs where two plates slip past each other. Convergent motion is where two plates push together Divergent motion occurs where to plates pull away from each other.

Table one:It tells what the plate motions are and what type of fault they create.

How do earthquake waves travel? They travel in two ways by P waves and S Waves.P waves: they move the earth's crust or rock back and forth which squeezes and stretches the rock as they travel.S waves:they shear side to side as it travels through the rock or the earth's crust.

How are the time and location of earthquakes determined? They use an instrument called a seismograph which is located near or at the surface of the earth to record seismic waves.A seismogram is a tracing of the information. Seismologists compare the data and noting the differences in the times the earthquakes come.Seismograms also figure out where the epicenter is which is a point located right above the earthquake's starting point.A focus is a point inside the earth where earthquakes begin.
