Which is true about the location of the asthenosphere?

• It is located just above the lithosphere.

• It is located in the lower part of the mantle.

• It is located in the upper part of the mantle.

• It is located in the inner core.

What is the point on the Earth's surface that lies directly above the site where an earthquake occurred?

• epicenter

• focus

• fault line

• seismic wave

At a dip-slip fault, pieces of land along the fault change position vertically when compared to one another. With this information, a student concludes that Earth's crust was uplifted years ago due to tectonic movements. If fossils provide evidence for Earth's history, which evidence would help the student justify this conclusion?

• fossils of marine animals found in ocean beds

• fossils of marine animals found in the mountains

• fossils of land animals found in deep oceanic trenches

• fossils of land animals found in recent igneous intrusions

• formation of an island

• destruction of a landform

• destruction of a forest

The movement of the tectonic plates is caused by

• the rotation of the Earth.

• convection currents in the Asthenosphere

• the gravity of the iron-nickel core.

• the Moho discontinuity.

In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?

• The strong ocean currents are undermining both areas causing earthquakes.

• Both areas are located near the edge of the Pacific Ocean, the unstable sand causes earthquakes.

• Both areas are subjected to strong ocean wind and waves that causes earthquakes.

• Both areas are on the boundary of active plates, the motion of the plates causes earthquakes.

Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that

• the oceanic crust is melting.

• the denser ceanic crust is subducting under the less dense oceanic crust

• volcanic islands are forming.

• the tectonic plates are moving away from each other.
