The Big Picture: “4 spheres”

Planet Earth:

The Earth’s Spheres: Atmosphere:

The Earth’s Spheres: Atmosphere: A mass of gas

surrounding a planet or other celestial body and held in place by gravity.

The Earth’s Spheres: Atmosphere: A mass of gas

surrounding a planet or other celestial body and held in place by gravity. Mostly Nitrogen (N) and Oxygen (O)

Composition of Atmosphere Nitrogen - 78% Oxygen - 21% Water Vapor – 0 to 4% Carbon Dioxide - .037% Other gases make up the rest

The Earth’s Spheres: Atmosphere: A mass of gas surrounding a planet or other

celestial body and held in place by gravity. Mostly Nitrogen (N) and Oxygen (O)

Hydrosphere:

The Earth’s Spheres: Atmosphere: A mass of gas surrounding a planet or other

celestial body and held in place by gravity. Mostly Nitrogen (N) and Oxygen (O)

Hydrosphere: All water located on the Earth, in the Earth, and in the Earth’s atmosphere.

The Earth’s Spheres: Atmosphere: A mass of gas surrounding a planet or other

celestial body and held in place by gravity. Mostly Nitrogen (N) and Oxygen (O)

Hydrosphere: All water located on the Earth, in the Earth, and in the Earth’s atmosphere. The water cycle.

The Earth’s Spheres: Lithosphere:

The Earth’s Spheres: Lithosphere: The land on Earth.

The upper layer of solid Earth.

The Earth’s Spheres: Lithosphere: The land on Earth.

The upper layer of solid Earth. Includes ocean bedrock and lake and

river beds.

The Earth’s Spheres: Lithosphere: The land on Earth. The upper layer of solid

Earth. Includes ocean bedrock and lake and river beds.

Biosphere:

The Earth’s Spheres: Lithosphere: The land on Earth. The upper layer of solid Earth.

Includes ocean bedrock, lake and river beds.

Biosphere: All forms of life on our planet.

Biosphere: What makes up the biosphere?

Look Familiar?

Biosphere: Where would you find the

biosphere? In the lithosphere. (worms, plant

roots, etc) In the atmosphere. (birds, trees, etc) In the hydrosphere. (fish, water

plants, etc)

Hydrosphere: Where would you find the hydrosphere?

Oceans Marshes Freshwater (lakes, rivers, springs, ponds,

puddles, etc.) Glaciers and polar caps as frozen

hydrosphere Ground water (under part of the lithosphere) Atmospheric water (clouds, water vapor, all

precipitation)

Hydrosphere: How does water move on our

planet? The water cycle

Layers of the Atmosphere Troposphere

The troposphere starts at the Earth's surface and extends to about 9 miles high. Almost all weather is in this region. Temperature decreases with height.

Stratosphere Air temperature increases with height

due to the sunlight absorption from the Ozone Layer. (average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the

top of the stratosphere.)

Atmosphere Mesosphere

Air thin, pressure low, very cold near top of layer. (the gases in the mesosphere are still thick enough to slow down meteors hurtling into the atmosphere, where they burn up, leaving fiery trails in the night sky. )

Thermosphere “Hot Layer” – oxygen molecules absorb

energy from solar Rays warming the air. Very few atoms and molecules in this region.

Atmosphere Exosphere

Very high up, the Earth's atmosphere becomes very thin. The region where atoms and molecules escape into space.

Excellent!
