Tectonic Boundaries

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often causing mountains, volcanoes, or earthquakes.

Front

What landforms can be created at a convergent boundary?

Back

Mountains, volcanoes, and ocean trenches.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, leading to the formation of new crust.

Front

What happens at a transform boundary?

Back

At a transform boundary, two tectonic plates slide past each other horizontally, causing earthquakes.

Front

What are the two types of crust?

Back

Continental crust and oceanic crust.

Front

What drives the movement of tectonic plates?

Back

The movement is driven by convection currents in the mantle, which are caused by heat from the Earth's core.

Front

What is the core of the Earth?

Back

The core is the innermost layer of the Earth, composed mainly of iron and nickel, and is extremely hot.

Front

What is the mantle?

Back

The mantle is the thick layer of rock between the Earth's crust and core, where convection currents occur.

Front

What is an example of a landform created by a divergent boundary?

Back

Mid-ocean ridges, such as the Mid-Atlantic Ridge.

Front

What is the difference between continental and oceanic crust?

Back

Continental crust is thicker and less dense than oceanic crust, which is thinner and denser.
