What are fossil fuels used for
heating homes, fuel cars/ planes and cook on stove
How is coal formed
1: Plants and tropical swamps die and mix with peat
2: Minerals covers the dead plants
3: Heat and pressure compress
4: Millions of years past and coal is formed
What are some problems with burining and mining coal
1: Miners can get black lung disease and chronic bronchitis
2: Air pollution can lead to sickness and global warming
3: Leaves scars on the land and tunnels can collapse leading to the death of workers
How is oil and natural gas formed
1: the remains of marine organisms that dies and sink to the bottom of the ocean
2: Sediment is placed on top
3: Heat and pressure are present
4: Water cements the rock and eventually forms oil and natural gas
What are some uses of oil and natural gas
heat homes, cooking, power cars, and lipstick
What are some problems with using oi and natural gas
Exposions, oil spills, pollution which can lead to climate change
Why do we have aquifiers
filter and store water
Aquifier def
An underground layer of rock, sand, or gravel that contains water
How does soil help us
It helps us grow food, home to worms, insects, and moles /animals
Defintion of fossil fuel
a substance containing energy that was formed hundreds of millions of years ago from te remains of ancient organisms
Distilliation definition
The action of purifying a liquid by the process of heating and cooling
Groundwater definition
Water stores below Earths surface in soil and rock
Is groundwater a renewable or nonrenewable resource
Renewable because people can use up groundwater faster than the Earth (natural process) can replenish it
