Front

What are mid-ocean ridges?

Back

Mid-ocean ridges are underwater mountain ranges formed by plate tectonics, specifically at divergent plate boundaries where tectonic plates move apart.

Front

True or False: Mid-ocean ridges take a long period of time to form.

Back

True

Front

True or False: Earthquakes, volcanoes, and tsunamis all occur in areas far from plate boundaries.

Back

False

Front

Where do mid-ocean ridges form?

Back

Mid-ocean ridges form where there are divergent plate boundaries.

Front

Where do earthquakes occur?

Back

Earthquakes occur along plate boundaries.

Front

What causes certain objects to float in or above others?

Back

Density differences cause certain objects to float in or above others.

Front

Why does Earth's crust float on the mantle?

Back

Earth's crust floats on the mantle because it is less dense than the mantle.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move away from each other, often resulting in the formation of new crust.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often resulting in one plate being forced below the other.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally.
