What are fossil fuels, and how are they formed?
Fossil fuels are natural energy sources like coal, oil, and natural gas, formed over millions of years from
the remains of dead plants and animals under heat and pressure.
What are the three main types of fossil fuels?
Coal, oil, and natural gas.
How does coal form differently compared to oil and natural gas?
Coal forms mainly from plant material in swampy areas, while oil and natural gas form from microscopic
marine organisms buried under sediments.
Why are fossil fuels considered non-renewable resources?
They take millions of years to form and cannot be replenished within a human lifetime.
What is the primary use of fossil fuels in modern society?
Fossil fuels are primarily used for energy production, such as generating electricity, powering vehicles,
and heating homes.
What environmental issues are caused by burning fossil fuels?
Burning fossil fuels releases carbon dioxide, contributing to climate change, as well as pollutants like
sulfur dioxide, which causes acid rain.
How does the use of fossil fuels contribute to global warming?
Fossil fuel combustion emits greenhouse gases like carbon dioxide, trapping heat in the atmosphere and
leading to a rise in global temperatures.
What are the main pollutants released during the burning of coal?
Coal combustion releases carbon dioxide, sulfur dioxide, nitrogen oxides, and particulate matter.
What is the role of fossil fuels in the production of electricity?
Fossil fuels are burned to produce steam, which drives turbines connected to generators, creating
electricity.
How does oil extraction affect the environment?
Oil extraction can lead to habitat destruction, oil spills, and water contamination, harming ecosystems
and wildlife.
What are some examples of products made from crude oil besides fuels?
Crude oil is used to make plastics, synthetic fibers, lubricants, and chemicals.
Why is natural gas considered cleaner than coal or oil?
Natural gas produces less carbon dioxide and fewer pollutants when burned compared to coal and oil.
What is "fracking," and how does it relate to fossil fuel extraction?
Fracking, or hydraulic fracturing, is a method of extracting oil and natural gas by injecting high-pressure
fluid into rock formations to release trapped resources.
