Question

Which statement of the following about the lithosphere is correct?

• A. It is the only ocean floor.
• B. It is the solid crust of Earth.
• C. It includes only soil.
• D. It includes air layers.

Hint:

Lithosphere = Land + Rocks + Earth's Solid Outer Layer.

Answer 1

The Correct Option is B

Concept: The Earth is composed of different spheres such as the lithosphere, hydrosphere, atmosphere, and biosphere. Each sphere has unique characteristics and functions.

Step 1: Understand lithosphere. The lithosphere refers to the Earth's solid outer layer consisting of:

• Crust.

• Uppermost part of the mantle.
It forms the rigid outer shell of the Earth.

Step 2: Features of the lithosphere. The lithosphere includes:

• Continents.

• Mountains.

• Plateaus.

• Ocean basins.
It is not limited to soil alone.

Step 3: Evaluate the alternatives. Ocean floor is only a part of the lithosphere. Soil forms only a thin layer. Air layers belong to the atmosphere. The most accurate description is that it is the Earth's solid crustal region.

Step 4: Conclusion. Hence, the lithosphere is the solid outer crust of the Earth. Therefore, option (B) is correct.
