Back

The inner core is an extremely dense sphere of solid iron and nickel at the center of the Earth.

Front

Where does gravity pull the densest material in a sphere?

Back

Gravity pulls the densest material to the middle of the sphere.

Front

Which material is most likely found in the Earth's core?

Back

Nickel, with a density of 4.6 g/ml, is most likely found in the Earth's core.

Front

What is the outer core of the Earth?

Back

The outer core is a liquid layer of the Earth's core, very dense and made of heavy metals.

Front

What is the primary composition of the Earth's inner core?

Back

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

Front

How does the temperature change as you move towards the Earth's core?

Back

The temperature increases significantly as you move towards the Earth's core.

Front

What is the state of matter of the outer core?

Back

The outer core is in a liquid state.

Front

What role does the mantle play in plate tectonics?

Back

The mantle's flow allows for the movement of tectonic plates on the Earth's surface.

Front

What is the approximate thickness of the Earth's crust?

Back

The Earth's crust is approximately 5 to 70 kilometers thick.
