2. Activity: For each Earth system, identify 2 examples you may find in each
Biosphere: global system integrating all living things and their relationships
Geosphere: the solid portion of the Earth
Hydrosphere: all waters on the Earth’s surface

3. Fossil Fuels

4. Fossil Fuels
What?: buried, combustible geologic deposit of organic material formed from decayed plants and animals exposed to heat and pressure over millions of years
Where?: concentrated where ancient swamps and oceans once were
Why?: decayed plants and organisms sank to the bottom of the water and over millions of years fossil fuels formed
Examples: petroleum (crude oil), natural gas, & coal

5. Minerals- Diamonds

6. Minerals- Diamonds
What?: pieces of solid carbon formed under intense heat and pressure
Where?: diamonds can be mined in igneous rock near volcano sites
Why?: diamonds can be found in the Earth’s mantle and come to the surface during volcanic eruptions

7. Minerals- Gold

8. Mineral- Gold
What?: a heavy element formed during a supernova (the end of a star’s life)
Where?: randomly dispersed on Earth and mined to extract
Why?: natural gold found in space after a supernova was incorporated into Earth’s layers during Earth’s formation

9. Soil

10. Soil What?: small pieces of rock and decomposed animal matter
Where?: soil can be found all over the Earth, but fertile soil can readily be found in river beds
Why?: running water breaks down rock and decomposed animal matter gets distributed with this rock pieces

11. Ground Water

12. Ground Water
What?: water found in tiny gaps between rock, soil, and sediments under the Earth’s surface
Where?: large aquifers can be found all over the Earth
Why?: aquifers are formed by rain and surface water seeping into the water table underground
