Fossils and Fuels SOL

What are fossil fuels?

• complex hydrocarbon compounds
• mixtures of gaseous hydrocarbons located under the surface of the Earth
• a nonrenewable energy resource formed the remains of organisms that lived long ago

Fossil fuels are classified as nonrenewable because they.......

• require expensive equipment
• take millions of years to replace
• can be found all over 
• provide all the energy we use

This is the cleanest burning of the fossil fuels:

• Natural Gas

• Coal

• Petroleum

• Shale

Crude oil is also called what?

• biomass
• fossils
• coal
• petroleum

As pressure and heat are added, this fossil fuel goes from Peat to lignite, then Bituminous and finally to Anthracite. 

• Coal
• Oil/ Petroleum
• Natural Gas

A consequence of mining for coal is

• Coal dust causes respiratory problems
• Coal mines can collapse
• Strip mining gets rid of all the soil that plants can use to grow on
• All of these

A consequence of drilling for petroleum is

• Oil spills can damage ecosystems
• It can cause acid precipitation
• It can cause respiratory issues
• All of the above

A consequence of burning coal is

• It releases sulfur dioxide, which combines with water in the air to form acid precipitation
• It contaminates water sources
• It causes withering away of trees
• All of these

In what kind of rock can fossils be found?

• Sedimentary Rocks
• Igneous Rocks
• Metamorphic Rocks
• Granite

How are fossils created?

• Traces of organisms get turned into stone.
• Dead organisms are quickly buried for millions of years.
• Animals get trapped.
• All of the above
