Multiple Choice

In which layer of the Earth is convection happening?

• Crust

• Mantle

• Inner Core

• Outer Core

Multiple Choice

Hot materials tend to ____ and cold materials tend to ____.

• rise; sink

• sink; rise

• sink; sink

• rise; rise

Multiple Choice

Heat from the ____causes convection in the ____.

• mantle; crust

• crust; mantle

• core; mantle

• core; crust

Multiple Choice

Why do Earth's plates move?

• the wind and tides push the plates around

• earthquakes cause Earth's plates to move

• they sit on top of the mantle which is convecting and moving

• they do not move because they sit on a layer of solid rock

Multiple Choice

What is the best description of the mantle?

• Solid rock that never moves

• Solid rock that moves and flows because it is so hot

• Liquid rock that flows just like water

• A fiery pit of lava

Multiple Choice

What is the correct order of the layers of the Earth?

• crust, mantle, inner core, outer core

• crust, mantle, outer core, inner core

• mantle, crust, outer core, inner core

• outer core, inner core, mantle, crust

Multiple Choice

What is the hottest layer of the Earth?

• crust

• mantle

• outer core

• inner core

Multiple Choice

What is the coolest layer of the Earth?

• crust

• mantle

• outer core

• inner core

Multiple Choice

Which type of crust is thinner?

• continental

• oceanic

• they are the same

Multiple Choice

Which type of crust is more dense?

• continental

• oceanic

• they are the same

Multiple Choice

What happens when two continental plates move toward each other

• mountains are formed

• volcanoes are formed

• tornados happen

• tsunamis happen

Multiple Choice

What happens when a continental plate and an oceanic plate move toward each other?

• volcanoes are formed

• mountains are formed

• Tornados happen

• Hurricanes happen

Multiple Choice

True or false: mountains and volcanoes are still being formed today.

• True

• False

Multiple Choice

What happens when two oceanic plates move away from each other?

• volcanoes are formed

• mountains are formed

• a mid ocean ridge is formed

• it leaves a big hole in the crust of the Earth

Multiple Choice

What is the process that happens at a mid ocean ridge?

• subduction

• convection

• sea floor spreading

• hotspots

Multiple Choice

What plate motion is happening at point A?

• convergent boundary

• divergent boundary

• transform boundary

• not enough info

Multiple Choice

What plate motion is happening at point B?

• convergent boundary

• divergent boundary

• transform boundary

• not enough info

Multiple Choice

What do you call an unusually hot place in the mantle that creates volcanic island chains like Hawai'i?

• Volcanic Hot plate

• Volcanic Hotspot

• Island Arc

• Convection

Multiple Choice

At a subduction zone, oceanic crust sinks back into the mantle. Part of it melts into magma which rises through the crust to form a volcano. Why does magma rise through the crust?

• magma is less dense than the crust rock

• magma is more dense than the crust rock

• magma is liquid and gets pushed up because of pressure

• magma is a solid and doesn't have to rise to reach the surface
