Plate Boundaries Flashcard

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide or move towards each other.

Front

What type of boundary forms the Andes Mountains?

Back

The Andes Mountains are formed by an oceanic-continental convergent boundary.

Front

Where are the youngest rocks found on the ocean floor?

Back

The youngest rocks are found near the mid-ocean ridge.

Front

What happens at a divergent boundary?

Back

At a divergent boundary, tectonic plates move away from each other, creating new crust.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally.

Front

What type of plates collide at a convergent boundary?

Back

At a convergent boundary, two oceanic plates, an oceanic and a continental plate, or two continental plates can collide.

Front

What geological features are commonly formed at convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs are commonly formed at convergent boundaries.

Front

What is the process of subduction?

Back

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

Front

What is the mid-ocean ridge?

Back

The mid-ocean ridge is an underwater mountain range formed by divergent tectonic plates.

Front

What is the significance of the Ring of Fire?

Back

The Ring of Fire is a major area in the Pacific Ocean where many earthquakes and volcanic eruptions occur due to tectonic plate boundaries.
