Earth's Interior

Front

What is the inner core of the Earth?

Back

The inner core is the solid, innermost layer of the Earth, composed mainly of iron and nickel, and has the greatest density.

Front

What is the mantle?

Back

The mantle is the thickest layer of the Earth, located between the crust and the outer core, and is made up of semi-solid rock that can flow.

Front

What is the outer core?

Back

The outer core is a liquid layer of the Earth located beneath the mantle and above the inner core, composed mainly of molten iron and nickel.

Front

What is the crust?

Back

The crust is the outermost layer of the Earth, consisting of solid rock and soil, and is the thinnest layer compared to the mantle and core.

Front

What is the asthenosphere?

Back

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

Front

What happens to less dense materials in the Earth's layers?

Back

Less dense materials rise to the top, while denser materials sink.

Front

Which layer of the Earth has the greatest density?

Back

The inner core has the greatest density of all Earth's layers.

Front

What is the relationship between the crust and the mantle?

Back

The crust is the outer layer that sits on top of the mantle, which is much thicker and denser.

Front

How does temperature change as you go deeper into the Earth?

Back

Temperature generally increases as you go deeper into the Earth due to the heat from the core.

Front

What materials primarily make up the Earth's inner core?

Back

The inner core is primarily made up of solid iron and nickel.
