Fossil Fuels are

• pieces of rock that have been compacted many times

• rock that contains 50% plant and animal remains

• metamorphic rock

• fuels that form from the remains of plant and other organisms that were buried and altered over million of years

This fossil fuel has been created by the remains of plants and must be mined from deep within the Earth.

• oil

• coal

• natural gas

• solar

This Fossil Fuel is highly flammable (catches on fire easily) and a leak could cause a violent explosion or fire.

• petroleum

• wood

• natural gas

This fossil fuel is formed from the remains of small organisms that lived in the ocean AND is a thick, black liquid

• natural gas

• coal

• oil

Some DISADVANTAGES of Fossil Fuels are (Select ALL that apply)

• air pollution

• acid rain

• climate change

• a lot of energy

How does coal form?

• Pressure builds in wetlands
• Pressure builds in trees
• Pressure builds in peat bogs
• Forms at the North Pole

How does petroleum form

• build up of layers of trees and leaves
• build up of once-living aquatic organisms underneath pressure and heat. 
• Build up of different rocks
• It's formed from gasses in the air
