How is the Earth Changing? Flashcard 2 Review 2022

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, leading to the formation of new crust, typically seen in oceanic regions.

Front

What feature is created at a divergent boundary in the ocean?

Back

Mid Ocean Ridge.

Front

What process occurs at a divergent oceanic boundary that creates new crust?

Back

Seafloor Spreading.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at a divergent boundary as magma rises from the mantle.

Front

What geologic feature is most likely found at a transform boundary?

Back

Earthquakes.

Front

What is a transform boundary?

Back

A transform boundary is a tectonic plate boundary where two plates slide past each other horizontally, often causing earthquakes.

Front

What is a deep ocean trench?

Back

A deep ocean trench is a steep, narrow depression in the ocean floor, typically formed at convergent boundaries where one plate subducts beneath another.

Front

What is the difference between a divergent boundary and a convergent boundary?

Back

A divergent boundary is where plates move apart, creating new crust, while a convergent boundary is where plates collide, often leading to subduction and mountain formation.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another and is forced into the mantle, often creating deep ocean trenches.

Front

What are rift valleys?

Back

Rift valleys are low-lying areas that form when tectonic plates move apart, often found at divergent boundaries on land.
