Formation of Fossil Fuels

Nonrenewable energy resource, such as oil and coal, formed over millions of years from the remains of dead plants and other organisms

• Natural Gas
• Oil
• Pressure
• Fossil Fuel

Rock made of layers of compressed organic and inorganic sediments

• Natural Gas
• Oil
• Pressure
• Sedimentary Rock

A flammable material, without a definte form, produced from organic materials(remains of marine organisms) buried under layers of sediment found near oil deposits

• Pressure
• Oil
• Natural Gas
• Fossil Fuel

A flammable liquid fossil fuel formed from marine organisms and buried under layers of sediments for millions of years.

• Natural Gas
• Fossil Fuel
• Pressure
• Oil

All of these are related to the formation of oil or natural gas EXCEPT -

• decomposed animals
• decayed plants
• sedimentary rocks
• active volcanoes

I am a solid energy source formed in swampy areas over millions of years.

• petroleum
• oil
• natural gas
• coal

I am a pocket of air released from the formation of oil and coal that becomes an energy source.

• oil
• oxygen
• natural gas
• coal

I am the process of organic materials breaking down over time.

• decay
• weathering
• delta
• erosion

Why are coal, oil and natural gas called fossil fuels?

• All of these sources of energy tap the power of long dead plants and animals.
• Rock like fossils are high in sulfur and other energy producing substances.
• Because they are old-fashioned power sources.
• Because they are generally found in the oldest parts of the Earth.

Which event began the formation of oil?

• the mixing of sea water with minerals

• the buildup of sea shells

• the eruption of a volcano

• the death of anciet marine (ocean) animals
