Unit 5 Topic 2M Flashcard

Front

What is a Divergent Boundary?

Back

A boundary where two tectonic plates move away from each other, allowing magma to rise and create new crust.

Front

What geological feature is commonly formed at a Divergent Boundary?

Back

Mid-Ocean Ridge.

Front

What occurs at a Convergent Boundary where oceanic crust and continental crust meet?

Back

Volcanoes are formed.

Front

What is a Convergent Boundary?

Back

A boundary where two tectonic plates move towards each other, often leading to subduction.

Front

What geological feature is formed due to subduction at a Convergent Boundary?

Back

Trenches.

Front

What is a Transform Boundary?

Back

A boundary where two tectonic plates slide past each other horizontally, causing earthquakes.

Front

What happens when plates at a Transform Boundary get stuck?

Back

They can cause earthquakes when they slip and release.

Front

What is sea-floor spreading?

Back

The process that occurs at Divergent Boundaries where new oceanic crust is formed as magma rises.

Front

What is subduction?

Back

The process where one tectonic plate moves under another, often occurring at Convergent Boundaries.

Front

What is the main cause of earthquakes at Transform Boundaries?

Back

The friction and stress that build up when plates get stuck.
