Earth Layers and Plate Tectonics

What are the two types of crust?

• continental and oceanic

• ocean and basin

• lower and upper

• thick and thin

The outer core is

• Layer of liquid metal.

• Outermost layer of the Earth.

• Made up of the lithosphere and asthenosphere.

• Innermost layer of solid metal.

The inner core is

• Layer of liquid metal.

• Outermost layer of the Earth.

• Made up of the lithosphere and asthenosphere.

• Innermost layer of solid metal.

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.
