Front

What is the outer core of the Earth?

Back

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

Front

Which type of crust is thicker, oceanic or continental?

Back

The continental crust is thicker than the oceanic crust.

Front

What happens to the density of rock as you move from the lithosphere to the inner core?

Back

The density of the rock increases as you move from the lithosphere to the inner core.

Front

What is the correct order of Earth's layers starting from the surface?

Back

The correct order is: Crust, Mantle, Outer Core, Inner Core.

Front

Why is the inner core solid despite being hotter than the outer core?

Back

The inner core is solid due to the immense pressure that prevents it from becoming liquid.

Front

What is the lithosphere?

Back

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

Front

What materials primarily make up the Earth's mantle?

Back

The mantle is primarily made up of silicate rocks that are rich in iron and magnesium.

Front

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

Back

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

Front

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

Back

In the Earth's interior, increased pressure can cause materials to remain solid even at high temperatures, as seen in the inner core.

Front

What is the composition of the Earth's crust?

Back

The Earth's crust is composed of a variety of rocks, primarily silicate minerals, and is divided into oceanic and continental crust.
