CLMS Earth Science Unit 6A Review

Front

What landform is formed by the collision of two tectonic plates at a convergent boundary?

Back

Marianas Trench

Front

What property of rocks remains unchanged when mountains are pushed higher due to tectonic plate collision?

Back

Total Mass is unchanged.

Front

What causes the volcanoes in the Hawaiian Islands?

Back

The tectonic plate moving over a hot spot where magma breaks through the crust.

Front

What evidence supports the theory that Earth's crust is made up of rocky plates that move over time?

Back

Magma wells up and forms a ridge down the middle of the Atlantic Ocean, creating new seafloor.

Front

What feature results when plates of different densities converge and one plate slips under the other?

Back

A trench.

Front

What is a tectonic plate?

Back

A large, rigid piece of the Earth's lithosphere that moves and interacts with other plates.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, often forming mountains or trenches.

Front

What is the process of subduction?

Back

The process where one tectonic plate slips under another, often leading to volcanic activity.

Front

What is a hot spot in geology?

Back

A location where magma from deep within the mantle rises to the surface, often creating volcanoes.

Front

What is the significance of the Mid-Atlantic Ridge?

Back

It is a divergent boundary where new oceanic crust is formed as tectonic plates move apart.
