Earth Systems Vocabulary Part 1

What is the brittle crust and uppermost part of the mantle?

• asthenosphere

• convection current

• lithosphere

• tectonic plate

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

• asthenosphere

• lithosphere

• magma plume

• pangea

What is a round, solid figure?

• convection current

• hot spot

• lava

• sphere

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

• normal fault

• reverse fault

• strike-slip fault

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

• normal fault

• reverse fault

• strike-slip fault

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

• normal fault

• reverse fault

• strike-slip fault

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?

• convection current

• lava
