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
magma
plate theory
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?
convection current
plate theory
subduction
What is a flow of unusually hot rock within the Earth's mantle?
lava
magma plume
volcano
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?
earthquake
Pangea
Ring of Fire
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.

What is melted rock above the Earth's surface?

magma
What are large, rigid pieces of rock that move below the surface of the Earth?
