DO NOW
  • 1. What is the layer beneath the Earth’s crust called?
  • 2. Which type of rocks are formed when layers of sediments and animal remains are cemented and compacted in water?
  • 3. Which type of rocks are formed from great heat and pressure deep within the Earth?

GOAL
  • To be able to distinguish between renewable and nonrenewable resources
fossil fuels1
What are fossil fuels?

1. Formed millions of years ago

2. Made from dead, compressed plant and animal remains

Fossil Fuels

What are fossil fuels?

3. Heat and pressure combines the remains with mud, sand and clay

4. Provide 90% of light and heat used to run homes and cars

Fossil Fuels

Why are fossil fuels useful?

1. Made of hydrocarbons that burn well

Wood doesn’t produce as much heat and energy when burned

Fossil Fuels

Why are fossil fuels useful?

2. Easy to store, transport and use

Problems with fossil fuels

1. When burned, release dangerous pollutants into the air

2. Nonrenewable- once used up they are gone (take millions of years to replenish)

  • Work with a partner and fill in the missing information on your fossil fuel summary chart

Coal

Solid form

Found buried in the Earth

Fossil Fuels

Coal

Four Types

1. Peat (soft, smokes, doesn’t burn well)

Fossil Fuels

Coal

Four Types

2. Lignite- brown, woody, not much energy

Fossil Fuels

Coal

Four Types

3. Bituminous- dark brown, common, found deep in Earth

Fossil Fuels

Coal

Four Types

4. Anthracite- black, hard, brittle, uncommon

Fossil Fuels

Oil

Liquid form

AKA Petroleum

Found in areas once covered with oceans

Fossil Fuels
fossil fuels15
Oil

Found where animal and plant remains layered, and were changed into oil by heat and pressure

Fossil Fuels
fossil fuels16
Oil

Found by drilling wells into rock deposits

Drill where oil seeps to surface or where top rocks test positive for carbon

Fossil Fuels
fossil fuels17
Natural Gas

Liquid form

Found near oil- rises to top of oil because its less dense

Fossil Fuels
fossil fuel uses
Uses for coal

Generates electricity

4. By 2080 we will have used up almost all fossil fuels

That have taken 500 million years for the earth to create

Drilling Paradise Dry
  • For homework, write a response to the “Drilling Paradise Dry” article- Do you agree or disagree with drilling for oil in Alaska- support your statement with several facts from the article.
  • Use the article response sheet
