Emerging - Fossil Fuels

After millions of years, layers of dead plants in a swamp are buried under mud and water. Over time, heat and pressure transform this material. What type of fossil fuel forms in this process?

• Natural gas

• Coal

• Oil

• Peat

In a large sea millions of years ago, tiny plants and animals die and sink to the bottom. Over time, sediment covers them, and heat and pressure transform them. What is formed as a result of this process?

• Wood

• Oil and natural gas

• Coal

• Peat

After oil forms deep underground, where does it go?

• It evaporates into the air.

• It rises through porous rocks.

• It sinks further into the Earth.

• It turns into coal.

What happens to buried organic material when heat and pressure increase over millions of years?

• It grows into new plants.

• It becomes fossil fuels like oil and gas.

• It turns into rocks.

• It stays the same.

A student claims that coal forms from ocean organisms. Which explanation would correct this misunderstanding?

• Coal forms from swamps, not oceans, using plants buried under pressure.

• Coal forms from volcanic rocks and hot lava underground.

• Coal forms in deserts where sand and sunlight break down plants.

• Coal forms from frozen water and glaciers trapping organic matter.

Why are layers of sediment important for fossil fuel formation?

• They provide oxygen for decay.

• They trap heat and pressure.

• They wash organic material away.

• They prevent fossil fuel formation.

Ethan is studying how natural gas forms and learns that oil and natural gas often form together. He wonders how they end up in the same location. Why do oil and natural gas often form in the same location?

• Both are made from the same type of rock.

• Both come from ancient marine organisms.

• Both form when oxygen mixes with plant material.

• Both are created by volcanic activity.

A swamp has been covered by a layer of mud for millions of years. What process is most likely happening below the surface?

• Plants are growing rapidly.

• Peat is forming under pressure.

• Oil is bubbling to the surface.

• Heat is evaporating water from the swamp.
