Презентация, доклад на тему Fossil fuel

disadvantages of fossil fuel usage, its role in human’s life and impact on the environment
Our tasks are:
to find out how fossil fuels formed
to define users and producers
to ascertain some problems concerning fossil fuel usage
Method of research is:
analysis

energy to make them run. About 90% of that energy comes from burning fossil fuels.
Fossil fuels include petroleum (oil), coal, and natural gas. These materials are called fossil fuels because, like fossils, they are remains of organisms (plants, animals, and other living things) that lived long ago.

millions years ago. Dead organisms sank into mud and rock. Over time many layers of rock built up. The remains of the organisms slowly changed in form to become different kinds of fossil fuels. Coal came from plants. Petroleum and natural gas came mainly from microscopic organisms such as algae.

plants use fossil fuels to produce electricity. People heat their homes and other buildings by burning fossil fuels. Gasoline, a product made from petroleum, fuels cars and other kinds of motorized equipment.

is Saudi Arabia. Russia has the largest reserves of natural gas. Major coal-producing countries include the USA and China.

fossil fuels at a faster rate than ever before. But the planet’s supply of fossil fuels is limited. Fossil fuels are called nonrenewable resources. Once they are used up, they will be gone forever.

petroleum and coal burn, they release harmful gases.







These gases react with moisture to create acid rain, a dangerous form of pollution.

This warming, called the greenhouse effect, may be harmful to living things.

generate power without using fossil fuels. For example, some cars are now powered by electricity instead of gasoline.






Homes can be heated by sunlight. Some electric power plants run on nuclear energy, water power or wind power.

the industrial society as these fuels are widely used in electricity generation, transportation and industry.
On the other hand the use of fossil fuel harms the environment causing acid rain, greenhouse effect.
That is why conservation measures for fossil fuels involve reduced usage and new ways to generate power.
