Earth Systems

In this unit, students explore how different parts of the Earth work together and affect each other. They learn that Earth is made up of four main systems that are always interacting.

The Four Earth Systems:

Geosphere – The solid parts of Earth

(rocks, mountains, land, etc.)

Hydrosphere – All the water on Earth 

(oceans, rivers, lakes, rain)

Atmosphere – The air and gases around Earth 

(weather, clouds, wind)

Biosphere – All living things

(plants, animals, people)

What Students Will Learn:

• How these systems interact (Example: How rain from the atmosphere affects the land)

• How natural events (like earthquakes or hurricanes) change Earth’s systems

• How human activities can affect the Earth, like pollution or farming

• How to use models and data to show how the Earth systems work together

Why This Unit Is Important:

This unit helps students understand how Earth works as a system. It also encourages them to think about how people affect the planet and how we can take care of it.
