Layers of the Earth & Plate Boundaries

Front

What are Earth's plates?

Back

Earth's plates are constantly moving and changing the face of the earth.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often causing one plate to be forced below the other.

Front

What type of boundary is the Mid-Atlantic Ridge?

Back

The Mid-Atlantic Ridge is formed at a divergent boundary.

Front

What is the outermost solid layer of the Earth called?

Back

The outermost solid layer of the Earth is called the crust.

Front

Where does the heat that drives convection currents in the mantle come from?

Back

The heat that drives convection currents in the mantle comes from the core.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move apart from each other, creating new crust as magma rises to the surface.

Front

What is a transform boundary?

Back

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

Front

What is the mantle?

Back

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

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 divided into the outer core and inner core.

Front

What happens at a convergent boundary?

Back

At a convergent boundary, tectonic plates collide, which can lead to the formation of mountains, earthquakes, and volcanic activity.
