Which evidence has led to the inference that solid zones and liquid zones exist within the Earth?

• analysis of seismic wave data

• the Earth's rotational speed during different seasons

• direct temperature measurements of the Earth's interior

• gravitational measurements made at the Earth's surface

The focus is the place inside Earth's crust where an earthquake originates.

The point on the Earth's surface directly above the focus is the epicenter.

Where did the earthquake begin?

• Focus

• Epicenter

• Fault

The most destructive part of a submarine earthquake is the production of:

• offshore trenches

• longshore currents

• tsunamis

• rip tides

Useful information regarding the composition of the interior of the Earth can come from earthquakes because earthquake waves :

• release materials from the earth

• travel through the Earth at a constant velocity

• travel at different rates through different materials

• change radioactive decay rates of rocks

This graph indicates that P-waves generally travel faster through rock materials that

• have greater density

• have undergone metamorphism

• are unconsolidated sediments

• are formed from marine-derived sediments

The landscape shown in the picture is an area of frequent earthquakes.

This landscape provides evidence for:

• converging convection cells within the rocks of the mantle

• movement and displacement of the rocks of the crust

• density differences in the rocks of the mantle

• differential erosion of hard and soft rocks of the crust
