What does heat do when convection currents are moving?

• Sinks

• Rises

• Stays in place

Colder, more dense magma near the crust...

• rises.

• sinks.

Hotter, less dense magma near the core...

• rises.

• sinks.

The plates of the crust move because...

• volcanoes erupt violently.

• of the weight of the oceans.

• of convection currents in the mantle.

• of the moon's gravity.

When molten  material is heated in the mantle the molecules

• expand (spread out)
• condense (shrink together) 
• stay the same
