What is the thinnest layer of the Earth?

Back

The crust is the thinnest layer of the Earth.

Front

What is the range of density values for the outer core?

Back

The density of the outer core ranges from 9.9 - 12.2 g/cm³.

Front

How does the density and composition of continental crust compare to oceanic crust?

Back

Continental crust is less dense and more felsic compared to oceanic crust.

Front

What causes the inner core to be solid?

Back

The inner core is solid due to the very high pressure at the core.

Front

Which layer of the Earth is molten (liquid metal)?

Back

The outer core is the layer of the Earth that is molten.

Front

What are the main components of the Earth's crust?

Back

The Earth's crust is primarily composed of silicate rocks, including granite and basalt.

Front

What is the composition of the outer core?

Back

The outer core is composed mainly of liquid iron and nickel.

Front

What is the temperature range of the inner core?

Back

The temperature of the inner core can reach up to 5,700 degrees Celsius.

Front

How does pressure affect the state of materials in the Earth's interior?

Back

High pressure can cause materials to become solid, as seen in the inner core.

Front

What is the difference between the lithosphere and asthenosphere?

Back

The lithosphere is the rigid outer layer of the Earth, while the asthenosphere is a semi-fluid layer beneath it.
