Convergent Boundaries

Front

What type of plate boundary occurs when plates move towards one another?

Back

Convergent boundary.

Front

What happens at a convergent boundary?

Back

Plates collide, leading to subduction or mountain formation.

Front

What is subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle.

Front

What type of crust is typically involved in subduction?

Back

Oceanic crust, which is denser than continental crust.

Front

What geological features can form at convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs.

Front

Why do oceanic plates subduct under continental plates?

Back

Because oceanic plates are more dense than continental plates.

Front

What is a volcanic arc?

Back

A chain of volcanoes formed above a subducting plate.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is thinner and denser, while continental crust is thicker and less dense.

Front

What is a transform fault?

Back

A boundary where plates slide past each other without creating or destroying crust.

Front

What is the Ring of Fire?

Back

A major area in the Pacific Ocean where many earthquakes and volcanic eruptions occur due to tectonic plate boundaries.
