An area where one convergent tectonic plate slides under another is called a ___________________ zone.

If subduction occurs between two oceanic plates, what type of geological formation is formed?

• coral reef

• mid-ocean ridge

When divergent plates in the ocean move away from each other, it is called sea-floor spreading. The process causes ___________ ________ to form.

Check boxes that are part of the inner earth.

• mantle

• asthenosphere

• geosphere

• inner core

The circular process of warm material rising and cooler material falling is called ____________

These things cause tectonic plates to move (check all that apply):

• heat on the inside of the earth

• convection in the mantle

• energy from the sun

• cosmic waves

Why do warm things (air, magma, etc.) want to rise?

• warm things are attracted to the sun

• warm things do not experience gravity
