Layers of the Earth: Beat the Teacher

Front

What is the Earth's mantle?

Back

The Earth's mantle is the layer located between the crust and the core, composed of semi-solid rock that flows slowly.

Front

What is the composition of the inner core?

Back

The inner core is composed mostly of solid iron and nickel.

Front

What is the asthenosphere?

Back

The asthenosphere is a part of the upper mantle that is semi-fluid and allows tectonic plates to move.

Front

What layer of the Earth is between the crust and the outer core?

Back

The mantle is the layer located between the crust and the outer core.

Front

What is the outermost layer of the Earth?

Back

The crust is the outermost layer of the Earth.

Front

What is the outer core made of?

Back

The outer core is composed of liquid iron and nickel.

Front

How thick is the Earth's crust?

Back

The Earth's crust is about 5 to 70 kilometers thick, depending on whether it is oceanic or continental.

Front

What is the temperature of the inner core?

Back

The temperature of the inner core can reach up to 5,700 degrees Celsius (10,300 degrees Fahrenheit).

Front

What is the difference between the inner core and outer core?

Back

The inner core is solid, while the outer core is liquid.

Front

What role does the mantle play in plate tectonics?

Back

The mantle's semi-fluid nature allows tectonic plates to move and shift, causing earthquakes and volcanic activity.
