Learning Objective
I can describe the structure and composition of Earth's geosphere.
- 1
The Earth is the largest of the terrestrial planets and has liquid water on its surface, which is essential for supporting life.
- 2
The Earth's interior consists of a solid inner core, a liquid outer core, a thick mantle, and a thin crust divided into plates.
- 3
The Earth's magnetic field, generated by the liquid outer core, protects the atmosphere from the solar wind, preventing it from being stripped away.
