Unit 4 Plate Tectonics Review

Front

What type of boundary is associated with the formation of ocean trenches?

Back

Convergent boundary.

Front

Why is the risk of earthquakes and volcanoes high along the Pacific coast of the United States?

Back

Because that's where the Pacific and North American plates meet.

Front

At which location are earthquakes least likely to occur in a tectonic plate context?

Back

Location 1 (typically away from plate boundaries).

Front

What is the term for the process when one lithospheric plate is pushed under another?

Back

Subduction.

Front

What is the term for the location where the edges of two tectonic plates meet?

Back

Plate boundary.

Front

What are the three main types of plate boundaries?

Back

Convergent, divergent, and transform boundaries.

Front

What geological features are commonly formed at divergent boundaries?

Back

Mid-ocean ridges and rift valleys.

Front

What is the primary cause of tectonic plate movement?

Back

Convection currents in the Earth's mantle.

Front

What type of boundary is characterized by plates sliding past each other?

Back

Transform boundary.

Front

What is the significance of the Ring of Fire?

Back

It is an area in the Pacific Ocean basin known for its high levels of seismic activity and volcanoes.
