Plate Boundaries

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move toward each other, often resulting in one plate being forced below the other, leading to geological features such as mountains or volcanoes.

Front

What geological feature is formed when convergent plates collide and both are pushed upward?

Back

Mountain Ranges.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move away from each other, often resulting in the formation of new crust, such as at mid-ocean ridges.

Front

What is the Mid-Ocean Ridge?

Back

The Mid-Ocean Ridge is a continuous mountain range that runs through the world's oceans, formed by the upwelling of magma at divergent plate boundaries.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, leading to earthquakes and fault lines.

Front

What is an example of a transform boundary?

Back

The San Andreas Fault in California is a well-known example of a transform boundary.

Front

What happens at a convergent boundary between an oceanic plate and a continental plate?

Back

The denser oceanic plate is subducted beneath the continental plate, often forming volcanic arcs and deep ocean trenches.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another and sinks into the mantle, often occurring at convergent boundaries.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, characterized by steep walls and a central block that has dropped down.

Front

What type of geological activity is common at divergent boundaries?

Back

Volcanic activity and the formation of new oceanic crust are common at divergent boundaries.
