Unit 4, Chapter 10 Review (Plate Tectonics)

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 diverging and new oceanic crust is created.

Front

What is the rate of movement of lithospheric plates?

Back

Lithospheric plates move at a rate of about 5 cm/year.

Front

What does the Mercalli Scale measure?

Back

The Mercalli Scale measures the intensity of an earthquake based on observable impacts on people, buildings, and the land surface.

Front

What geologic feature is traced by a world map showing earthquake locations?

Back

A world map showing earthquake locations traces out tectonic plate boundaries.

Front

Where is oceanic lithosphere destroyed?

Back

Oceanic lithosphere is destroyed at convergent boundaries.

Front

What are tectonic plate boundaries?

Back

Tectonic plate boundaries are the edges where two tectonic plates meet, which can be divergent, convergent, or transform boundaries.

Front

What is a Rift Valley?

Back

A Rift Valley is a lowland region formed by the divergence of tectonic plates, often characterized by steep walls and a central block.

Front

What is a transform fault boundary?

Back

A transform fault boundary is a type of plate boundary where two plates slide past each other horizontally.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, leading to subduction or mountain building.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another and is forced into the mantle.
