How thick is the lithosphere?

Correct option is C

The correct answer is (c) 10 to 200 kilometers.

• The lithosphere is the rigid outer layer of the Earth, which includes the crust and the uppermost mantle. Its thickness varies, typically ranging from 10 kilometers beneath oceanic regions to about 200 kilometers under continental regions. The lithosphere is the solid, outer part of Earth. The lithosphere is composed of rocks and minerals.

Interior of the Earth:

• Crust: The Earth's outermost layer, divided into oceanic (5-10 km) and continental crust (25-70 km).
• Mantle: Beneath the crust, extending to about 2,900 km depth, composed of semi-solid silicate minerals.
• Outer Core: A liquid layer of iron and nickel, extending from 2,900 km to 5,150 km.
• Inner Core: The solid innermost layer, composed primarily of iron and nickel, with a radius of about 1,220 km.
