What does lithosphere refer to?

  1. Water

  2. The land

  3. Air

  4. Sky

The correct answer is: The land

The lithosphere refers specifically to the rigid outer layer of the Earth, which encompasses the crust and the uppermost part of the mantle. It includes all the landforms and geological features present on the Earth's surface, such as mountains, valleys, and plains. This definition aligns directly with the concept of "the land," as it represents the solid, terrestrial aspects of our planet, distinguishing it from elements like water, air, or the sky, which are part of other spheres of the Earth's system. Thus, identifying the lithosphere as "the land" accurately reflects its geological significance and structure.
