Earth's Interior

A break in a body of rock along which one block slides relative to another is a

• core

• fault

• mantle

• lithosphere

The process by which one lithospheric plate moves beneath another as a result of tectonic forces is known as

• transaction

• subduction

• collision

• evaporation

• sublimation

The solid, outer layer of Earth that consists of the crust and the rigid upper part of the mantle

• lithosphere

• crust

• mantle

• core

• inner mantle

The center part of Earth below the mantle

• crust

• mesosphere

• core

• mantle

• lithosphere

The thin and solid outermost layer of the Earth above the mantle.

• inner core

• outer core

• crust

• mantle

• lithosphere

The location within the earth along a fault at which the first motion of an earthquake occurs.

• stratosphere

• focus

• mesosphere

• radius

• sphere

A seismic wave that travels along the surface of a medium and has a stronger effect near the surface of the medium than it has in the interior

• p-waves

• s-waves

• surface waves

• longitudinal waves

• transverse waves

A scale that expresses the magnitude of an earthquake

• Magnetic scale

• Calibrated scale

• Moh's scale

• Richter's scale

• Equilibrium scale

The point on the earth’s surface directly above an earthquake’s starting point or focus

• Focus

• Epicenter

• Center

• End point

• Radius

In a shield volcano

• the lava thin and runny, and causes a gentle explosion

• the lava is thick and sticky and causes a violent explosion

• there is no lava

• magma is thick, sticky and comes out with an explosion

• both magma and lava are thick and sticky
