What is the crust?

Back

The crust is the outermost layer of the Earth where we live. It is solid and relatively thin compared to other layers.

The two types of crust are continental crust and oceanic crust.

Front

What is the mantle?

Back

The mantle is the thickest layer of the Earth, located between the crust and the outer core. It is semi-solid and allows for the movement of tectonic plates.

Front

What is the inner core?

Back

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

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.

Front

What is tectonic plate movement?

Back

Tectonic plate movement refers to the shifting of the Earth's plates that can cause earthquakes, volcanic activity, and the formation of mountains.

Front

What causes earthquakes?

Back

Earthquakes are caused by the sudden release of energy in the Earth's crust due to tectonic plate movements.

Front

What is a fault line?

Back

A fault line is a fracture or zone of fractures between two blocks of rock, which can lead to earthquakes.
