Question

the ______________ is the crust, which covers the earth.
○ hydrosphere
○ lithosphere
○ atmosphere
○ biosphere

Explanation:

To solve this, we analyze each option:

• Hydrosphere: Relates to water bodies (oceans, lakes, etc.), not the crust.
• Lithosphere: Defined as the rigid outer layer of the Earth, including the crust and upper mantle. This matches the description of the crust covering the Earth.
• Atmosphere: Is the gaseous layer surrounding the Earth, not the crust.
• Biosphere: Encompasses all living organisms and their environments, not the crust.

Answer:

B. lithosphere
