Questions and Answers

What is the geosphere?

  • The outermost layer of the Earth, including the crust and upper mantle.
  • The solid part of the Earth, including the lithosphere, mantle, and core. (correct)
  • The liquid outer core of the Earth.
  • The part of the Earth's crust that makes up the continents.

What is the lithosphere?

  • The layer of the Earth between the crust and the core.
  • The rigid outer layer of the Earth, including the crust and upper mantle. (correct)
  • The innermost layer of the Earth, consisting of a solid inner core and a liquid outer core.
