Earth's Interior

Front

What is the asthenosphere?

Back

The asthenosphere is a layer of the Earth's mantle that can flow slowly, allowing tectonic plates to move.

Front

What is the outer core?

Back

The outer core is a layer of the Earth that is completely liquid and is located beneath the mantle and above the inner core.

Front

What is the inner core?

Back

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

Front

What is the crust?

Back

The crust is the outermost layer of the Earth, which is the least dense layer and includes the continents and ocean floors.

Front

What is the mantle?

Back

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

Front

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

Back

The outer core is liquid, while the inner core is solid due to the immense pressure at the Earth's center.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle.

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where life exists on Earth, but it is not a layer of the Earth.

Front

What is the magnetosphere?

Back

The magnetosphere is the region around the Earth dominated by its magnetic field, protecting the planet from solar wind.

Front

What is the relationship between density and Earth's layers?

Back

The density of Earth's layers increases as you move from the crust to the inner core, with the crust being the least dense.
