Plate Motion Review

Front

What is a Mid-Ocean Ridge?

Back

A Mid-Ocean Ridge is an underwater mountain range formed by plate tectonics, where tectonic plates are moving apart, allowing magma to rise and create new oceanic crust.

Front

At which boundary do you find a trench?

Back

A trench is found at a Convergent boundary, where one tectonic plate is being forced under another.

Front

What does 'Rate' refer to in geological terms?

Back

Rate refers to how often or fast something happens, such as the speed of tectonic plate movement.

Front

What evidence suggests that two continents were once connected?

Back

Identical landforms and similar rock formations on both continents suggest they were once connected.

Front

What best describes Earth's mantle?

Back

The mantle is the soft, solid rock layer beneath the Earth's crust on which tectonic plates move.

Front

What is a tectonic plate?

Back

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

Front

What happens at a Divergent boundary?

Back

At a Divergent boundary, tectonic plates move apart, leading to the formation of new crust, often seen at mid-ocean ridges.

Front

What is a Convergent boundary?

Back

A Convergent boundary is where two tectonic plates collide, often resulting in one plate being forced beneath another, creating trenches or mountains.

Front

What is the significance of volcanic activity in plate tectonics?

Back

Volcanic activity often occurs at plate boundaries, especially at Divergent and Convergent boundaries, indicating the movement of tectonic plates.

Front

What is an earthquake?

Back

An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere.
