Fosseil Fuels

What are the three main types of fossil fuels?

• Solar, wind, and hydro

• Coal, oil, and natural gas

• Wood, peat, and biomass

• Uranium, plutonium, and thorium

How are fossil fuels formed?

• From volcanic eruptions and lava flows

• Through the rapid decomposition of minerals in the earth's crust

• From the decayed remains of ancient plants and animals buried under pressure for millions of years

• By synthetic processes in underground laboratories

Which type of coal is the most common and is 100 to 300 million years old?

• Anthracite

• Bituminous

• Subbituminous

• Lignite

What are some of the reasons people are trying to move away from coal as a main source of energy?

• It is too expensive to mine

• It is dirty, pollutes the air and water, and mining it can be dangerous and harmful to the earth

• It is not efficient enough to produce electricity

• It is only found in a few remote locations

Where are most oil deposits formed?

• Near the surface of deserts

• At the bottom of ancient oceans

• In volcanic rock formations

• Within mountain ranges

Which of the following products can be made from crude oil after it is refined?

What is a significant environmental problem associated with burning fossil fuels like oil and natural gas?

• Increased biodiversity

• Reduced air pollution

• Greenhouse gas emissions

• Enhanced water quality

Why is mercaptan added to natural gas before it is distributed for use?

• To increase its heating efficiency

• To give it a distinctive smell for leak detection

• To change its color for identification

• To make it less flammable
