What is the relationship between the outer layer and the mantle?

Back

The mantle is always below the outer layer and is not exposed to the surface.

Front

What evidence supports the theory of plate tectonics regarding the movement of continents?

Back

Fossil remains of Lystrosaurus found in India and South Africa indicate that these continents were once connected.

How do tectonic plates move apart?

Back

Tectonic plates slowly move apart as soft, solid rock from underneath gets added to the edges of the plates over millions of years.

Front

What happens when tectonic plates collide?

Back

When tectonic plates collide, one plate may go under the other into soft, solid rock, causing geological activity.

What is a cross section?

Back

A cross section is a cut through an object that shows its internal structure.

Front

What can scientists learn from studying cross sections?

Back

Scientists can better understand the internal structure and composition of objects.

Front

What causes plate motion?

Back

Plate motion is primarily caused by convection currents in the mantle, not just earthquakes.

What is the role of magma in plate tectonics?

Back

Magma rises from the mantle and can create new crust at divergent plate boundaries.
