2. The Lithosphere
The crust and the rigid part of the mantle make up what is called the Lithosphere
Pangaea is a theory that made the continents into one supercontinent
Continental drift is when Pangaea drifted apart into the continents that we have today
Plate tectonics explain how continents and the ocean floor could move
Volcanism is when it brings materials from the inside of the Earth to the outside.
Lithosphere is always moving, but very slowly.

3. The Hydrosphere Part of the Earth that contains water
This includes lakes, rivers, hail, rain, sleet, snow, oceans, fog, ice, and clouds
Covers about 75% of the Earth’s surface
Home to many plants and animals
Water cycle includes evaporation, condensation, precipitation, and runoff
Precipitation is water that falls from clouds to the ground in the form of rain, sleet, hail, or snow.
Aquifers are an underground body of water

4. The Atmosphere Layers of gases that surround the Earth
Earth’s atmosphere is made up of 79% nitrogen, 20% oxygen, and 1% other gases.
The relationship between air pressure and height is that the higher you go the less air pressure or the lower your height is the more air pressure there is.
If you are on a mountain, it is harder to breathe, than if you were at sea level. The height, or altitude, determines how much air pressure there is.

5. The Atmosphere
The layers of the atmosphere include the thermosphere, mesosphere, stratosphere, and the troposphere
The troposphere, the lowest layer, is where all the weather takes place.
Ozone layer is part of the stratosphere that prevents nearly 99% of the sun’s ultraviolet rays from reaching the Earth.

6. The Biosphere Layer of the planet Earth where life exists
There has been no existence of life elsewhere in the universe besides the biosphere
Its components include between 3 to 30 million species of plants, animals, fungi, and bacteria

7. The Biosphere
Ecosystems are living and nonliving things that work together some types include: forest, desert, and tundra
Food chain is a model of the path that the energy in food takes as it moves from one organism to the next in an ecosystem
The biosphere is the one place where all of the other spheres interact.

8. The Sphere’s Interaction
The atmosphere provides oxygen for the living things in the biosphere.
The hydrosphere provides water for the soil (lithosphere) which allows plants to grow.
The hydrosphere provides water for animals, humans, and plants to drink in order to survive.
The remains of animals, humans, and plants (biosphere) put nutrients back into the soil (lithosphere).
The components of the biosphere affect all the other spheres by what we do. (pollution, construction, poor use of resources, etc.)
The atmosphere protects the biosphere from the sun’s radiation.
