asthenosphere

b)

convection current

c)

lithosphere

d)

tectonic plate

2.

What is the solid, almost flowing, layer of Earth below the lithosphere?

a)

asthenosphere

b)

lithosphere

c)

magma plume

d)

pangea

3.

What is a round, solid figure?

a)

convection current

b)

hot spot

c)

lava

d)

sphere

4.

What is a break caused by shearing (causes rock on either side of fault to move in opposite directions)?

a)

normal fault

b)

reverse fault

c)

strike-slip fault

5.

What is a break caused by tension (pulls rock apart)?

a)

normal fault

b)

reverse fault

c)

strike-slip fault

6.

What is a break caused by compression (pushes or squeezes rock together)

a)

normal fault

b)

reverse fault

c)

strike-slip fault

7.

What is the process where warm fluid in the Earth’s mantle becomes less dense and rises; the fluid then cools, becomes more dense, and sinks back down?

a)

convection current

b)

lava

c)

magma

d)

plate theory

8.

What is a process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced or sinks due to gravity into the mantle?

a)

convection current

b)

plate theory

c)

subduction

9.

What is a flow of unusually hot rock within the Earth's mantle?

a)

lava

b)

magma plume

c)

volcano

10.

What is a region of high volcanic and seismic activity that surrounds the majority of the Pacific Ocean Basin which is made up of converging plate boundaries?

a)

earthquake

b)

Pangea

c)

Ring of Fire

11.

What is a process when magma rises through the cracks in the Earth’s crust and erupts to form volcanoes? As the tectonic plates continue to move over a stationary hotspot, the volcanoes break away and move along with the plate allowing new volcanoes to form in their place.

a)

earthquake

b)

hot spot

c)

lava

d)

magma

12.

What is melted rock below the Earth's surface?

a)

lava

b)

magma

13.

a)

lava

b)

magma

c)

magma plume

d)

tectonic plates

15.

What is the supercontinent that was made up of all current continents fitting together?

a)

earthquake

b)

Pangea

c)

Ring of Fire

d)

tectonic plate
