How do folded mountains form?

Back

They form when plates collide or push against each other.

Front

What processes can result in the formation of high mountains with well-rounded peaks?

Back

Movement of tectonic plates and erosion.

A massive slab of Earth's lithosphere that moves and interacts with other plates.

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by natural processes.

Front

What is the difference between a dominant and recessive allele?

Front

What is the Geologic Time Scale?

Back

A system of chronological dating that relates geological strata to time.

Front

What is the role of tectonic plates in earthquakes?

Back

Earthquakes occur when tectonic plates shift and release energy.
