Earth's Systems Vocabulary

Explore the interconnected systems of the Earth:

• Geosphere - the Earth

• Hydrosphere - water on Earth

• Atmosphere - the air surrounding Earth

• Biosphere - all living organisms

• Lithosphere- solid part of Earth made up of rocks, minerals, and other elements, not including the oceans.

• Cryosphere- includes all of Earth's frozen water including glaciers, permafrost and sea ice.

​Use the following slides to refresh your memory on the meaning of the vocabulary words.
