Spheres Mind Map

​

Atmosphere

• Layer of gases around Earth

• Mostly made up of nitrogen and oxygen

• Includes weather, clouds, and the air we breathe

• Reaches from the Earth's surface to about 10,000km high

Hydrosphere

• All of Earth's water, including oceans, lakes, rivers, ice, groundwater, snow, etc. Clouds are also a part of the hydrosphere

• Covers about 71% of the Earth's surface

• Solid, liquid, and gas

Biosphere

• All living things, i.e. animals, plants, bacteria, and fungi

Lithosphere

• The solid outer part of Earth: rocks, soil, and crust

You don't need to write this part but note that it does note include all the solid parts of Earth - like down to the core. Think skin of an apple versus the whole apple.

Global Event Activity

At each event station, read the clues carefully and figure out what happened. Then, analyse how the event affected each of the four spheres.

In your books, for each station, complete:

• What do you think the event is?

• Describe the impact on each sphere.

• How do the spheres interact?
