Earth's Interior

What is the asthenosphere?

Back

The asthenosphere is a layer of the Earth's mantle located below the lithosphere, characterized by its semi-fluid nature, allowing for the movement of tectonic plates.

Front

Which layer of the Earth is completely liquid?

Back

The outer core is the layer of the Earth that is completely liquid, composed mainly of molten iron and nickel.

Front

What is the structure of the Earth's core?

Back

The Earth's core has a solid inner part (inner core) and a liquid outer part (outer core).

Front

Where is heat and pressure the greatest in the Earth?

Back

Heat and pressure are greatest in the inner core, which is the innermost layer of the Earth.

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 mantle?

Back

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

Front

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

Back

The inner core is solid and composed mainly of iron and nickel, while the outer core is liquid and also made of iron and nickel.

Front

What role does the asthenosphere play in plate tectonics?

Back

The asthenosphere allows tectonic plates to move due to its semi-fluid nature, facilitating geological processes like earthquakes and volcanic activity.

What is the composition of the Earth's crust?

Back

The Earth's crust is composed of solid rock, including both continental crust (granite) and oceanic crust (basalt).

Front

How does temperature change with depth in the Earth?

Back

Temperature generally increases with depth in the Earth, reaching extremely high temperatures in the inner core.
