Tectonic Plate Theory

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often resulting in geological features such as mountains, earthquakes, and volcanic activity.

Front

What happens at a convergent boundary between continental plates?

Back

At a convergent boundary between continental plates, the plates may collide, leading to the formation of mountain ranges and causing earthquakes.

Front

What is subduction?

Back

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

Front

What landform is typically created at an oceanic-oceanic convergent boundary?

Back

A deep trench is typically created at an oceanic-oceanic convergent boundary.

Front

Who proposed the theory of continental drift?

Back

Alfred Wegener proposed the theory of continental drift, suggesting that continents were once joined and have since drifted apart.

Front

What is a volcanic arc?

Back

A volcanic arc is a chain of volcanoes formed above a subducting plate, typically found at convergent plate boundaries.

Front

What geological feature is formed when an oceanic plate subducts under a continental plate?

Back

When an oceanic plate subducts under a continental plate, it can lead to the formation of mountain ranges and volcanic activity.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are denser and thinner than continental plates, which are thicker and less dense.

Front

What is the result of a collision between two continental plates?

Back

The collision of two continental plates can result in the formation of mountain ranges and significant seismic activity.

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.
