How Does Earth Work?

Earth is made up of several interconnected systems that work together to support life.

Main Earth Systems

• Geosphere: The solid part of Earth, including rocks and soil.
• Hydrosphere: All the water on Earth, like oceans, lakes, and rivers.
• Atmosphere: The layer of gases that surrounds the planet.
• Biosphere: All living things on Earth.

System Interactions

These systems interact constantly. Rain falls from the atmosphere, eroding rocks in the geosphere and providing water for plants in the biosphere.

Real-World Connections

Understanding Earth’s systems helps us predict weather, find resources, and protect the environment.
