Plate Tectonics & Boundaries

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, rift valleys, and volcanic activity.

Front

What happens at a convergent plate boundary?

Back

At a convergent plate boundary, two tectonic plates collide, which can lead to the formation of mountains, earthquakes, and subduction zones.

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

Who proposed the Continental Drift Theory?

Back

Alfred Wegener proposed the Continental Drift Theory, suggesting that continents were once joined together and have since drifted apart.

Front

What are the four layers of the Earth?

Back

The four layers of the Earth are the crust, mantle, outer core, and inner core.

Front

How does convection affect the Earth's plates?

Back

Convection in the mantle causes the movement of tectonic plates, leading to geological activity such as earthquakes and volcanic eruptions.

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 geological features can form at divergent boundaries?

Back

Geological features such as rift valleys, mid-ocean ridges, and new oceanic crust can form at divergent boundaries.

Front

What is a transform plate boundary?

Back

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

Front

What is the role of tectonic plates in earthquakes?

Back

Tectonic plates can cause earthquakes when they move, collide, or slide past each other, releasing energy in the Earth's crust.
