Where will you find the oldest rocks within the oceanic crust?

• closest to the ridge
• in the middle of the ocean
• farthest from the ridge
• at divergent boundaries

When the Indian plate crashed into the Eurasian plate, it created the 

• Andes Mtn Range
• Himalayan Mountains
• Mauna Loa
• Pangaea

When two oceanic plates converge, this eventually forms.

• glaciers
• volcanic island arc
• mountain range
• divergent boundary

When an oceanic plate and a continental plate converge, what forms?

• volcanic mountain range

• volcanic island arc

• Himalayan mountains

• Mid-Ocean Ridge

When two continental plates converge, what forms?

• mid-ocean ridge
• oceanic trench
• volcanic mountains
• mountain range

What is responsible for moving tectonic plates?

• conduction
• ocean floor spread
• the lithosphere
• convection

Where in the Earth does the convection the drives plate tectonics occur?

• Crust
• ocean 
• mantle
• core

What powers convection in the mantle?

• heat from the core
• heat from the sun
• heat from a volcano
• heat from a geyser

The mid-ocean ridge forms at this type of boundary:

• divergent

• transform

• subduction

• convergent

When oceanic plate subducts, a ____ forms.
