What are the layers of the Earth?

Back

The Earth has four main layers: the crust, mantle, outer core, and inner core.

Front

What is the outer core made of?

Back

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

Front

Why is the inner core solid?

Back

The inner core is solid due to the immense pressure that exists at the center of the Earth.

Front

What is foliation in rocks?

Back

Foliation is the process where rocks develop a layered or banded appearance due to pressure.

Front

What causes the Earth's crust to move?

Back

The movement of tectonic plates causes the Earth's crust to shift.

Front

What is the difference between the crust and the mantle?

Back

The crust is the outermost layer, while the mantle is beneath the crust and is made of semi-solid rock.

Front

What is the composition of the mantle?

Back

The mantle is composed of silicate rocks that are rich in magnesium and iron.

Front

How does pressure affect rocks?

Back

Increased pressure can cause rocks to deform, change structure, or become metamorphic.

Front

What is the significance of the Earth's layers?

Back

The layers of the Earth affect geological processes, including earthquakes, volcanic activity, and the formation of minerals.

Front

What is the role of the outer core in Earth's magnetic field?

Back

The movement of liquid iron in the outer core generates Earth's magnetic field.
