Atmosphere: Gaseous mass Surrounding a celestial body

Important because: To breathe and to maintain temperature. Layers MesosphereStratosphereTroposphere

Biosphere:

Hydrosphere: Aqueous vapor of the atmosphereIncluding bodies of water

Important because:Water is lifeLifeBiodiversityBeauty, religion, culture and experience

Lithosphere: the rigid outer layers of Earths surface; is composed of (form outer to inner) the continental crust, the oceanic crust, and the upper most mantle, all floating on the semi-molten rock of the mantle.

How is new rock made? Where does the material for new rock come from?VolcanoesEarthquakes

Magma (when its inside the volcano) Lava (when it comes out) Then when it dries out it become hard, it become a rock

Connections:

Lithosphere and hydrosphere:Helps create the worlds water supply.

Atmosphere and lithosphere:

Biosphere and lithosphere:-Most plants on earth require soil to grow-All other life on Earth depends on

Biosphere and hydrosphere:All life on earth requires water to survive.

Diversity: variety

How many different species exist on Earth? Scientists have identified 2 million speciesTen million remain unknown

3 components of biodiversity: 1. Diversity of genes

Why is genetic diversity important?

2. Diversity of species:

3. Variety of ecosystems:

Biodiversity has intrinsic value and Utilitarian value

Intrinsic value: Something that has value in and of itself

Utilitarian value: the value something has as a means to another end.

Utilitarian values include: Goods Services Information
