Bc Plate Tectonics Topographic

Every few hundred thousand years the magnetic poles of Earth reverse. Rocks that contain iron provide a record of both normal and reversed magnetic poles. The pattern of normal and reversed magnetic poles as recorded in the rock on either side of the Mid-Atlantic Ridge provide evidence supporting Plate Tectonic Theory because -

• the bands of rock showing normal and reversed poles are not all the same width.

• the symmetric pattern shows where plates are moving away from each other.

• the composition of the rock changed every time the plates pushed against each other.

• deposits of iron in the rock were only made when the plates stopped moving.

Examining rocks that form on either side of the Mid-Atlantic Ridge provides evidence that supports the theory of Plate Tectonics. This is because we see evidence of plate movement in the fact that as we look at rocks farther and farther from the ridge, the rocks -

• have higher iron content.

• are made up of smaller particles.

• become thicker and thicker.

• are consistently older.

The most recently formed crust on Earth would be found where -

• plates are moving sideways past each other.

• one plate is sliding under another plate.

• two plates are pushing directly towards each other.

• two plates are moving apart from each other.
