All of the following are evidence that supports the theory of seafloor spreading EXCEPT:

matching coal fields on 2 continents.

A foliated metamorphic rock:

has mineral grains lined up in bands

As you go deeper into the Earth,

temperature and pressure both increase.

Why was Wegener's theory of continental drift rejected?

He couldn't explain what was causing the continents to move.

Tectonics plate move because:

the asthenosphere moves plates in the lithosphere.

Earthquakes occur when:

an 2 plates move horizontally past each other.

All of the following are evidence that support the theeoy of continental drift except:

molten material on the ocean floor.

An intrusive, granitic igneous rock would:

have large crystals and light color

Convection occurs in the mantle because:

rock heated by the core bcomes less dense and rises.
