Fossils A fossil is the prehistoric remains of a plant or an animal. Fossils are usually are kept at their best when they are buried under many layers of sand and mud. Under the great pressure from the ground‚ the sand and the mud become sedimentary rock. The minerals combine forming a mould of the plant or animal under the ground. A fossil can be a trace fossil or a body fossil. A body fossil is what actual organic material from a creature or plant (like a bone). Trace fossils are signs of

How can alternative sources of energy be harnessed effectively? In modern society‚ an increasing number of people pay more attention to how to make use of alternative sources of energy effectively.With the development of economy and society‚ existing energy sources have been hard to meet the increasing market demands. Therefore‚ alternative energies become more and more important because they are directly related to the future economic and social development. Therefore‚ this essay will discuss

can alternative sources of energy be harnessed effectively? Finding Alternative energy sources is a significant issue from all over the world. In contemporary society‚ due to the lack of fossil fuels and environmental problems like air pollution‚ alternative sources of energy have being utilized widely for different domestic and industrial applications. Biogas is one of the alternative energy which instead of fossil fuels. This

FURTHER USES OF PETROLEUM Gasoline fuels our cars and natural gas heats our homes‚ but have you ever wondered what life would be like without the countless products derived from natural gas and oil? In our modern world‚ we have come to enjoy and expect a certain quality of life that is sustained by everyday things made from these natural resources. Think about a typical weekday. You brush your teeth‚ shower‚ put on makeup or shave before heading off to work. Without petroleum-based products‚

Although they only span 6% of the surface of the Earth‚ rainforests contain more than half of the world’s plant and animal species. The amount of species that live in the rainforest is greater than 30 million plants and animals. In addition to plants and animals‚ nearly 50‚000‚000 tribal people live in the world’s rainforests. They depend on the rainforests to provide them with food and shelter. The rainforest

1st Draft Nowadays‚ There are many alternative sources of energy for people to use. In the past people make fire by cracking two pieces of flint causing sparks against dry tinder or fleece. But now people use technology for their needed. People have used more than 90% of fuels‚ such as oil‚ coal and natural gas to produce electricity. These things are non-renewable. The more we use these fuel it will decreases everyday. So we have to find another

by burning fossil fuel it will release CO2: in the case of coal fuel 295 kg/t; in the case of natural gas fuel 206 kg/t. The electric power consumption of an efficient plant is around 20 kWh per tonne of lime. This additional input is the equivalent of around 20 kg CO2 per ton if the electricity is coal-generated. Thus‚ total emission may be around 1 tonne of CO2 for every tonne of lime even in efficient industrial plants‚ but is typically 1.3 t/t.However‚ if the source of heat energy used in its

and wood as a natural resource to produce energy. Around the beginning of the twenty-first century‚ those same energy resources are routine today as they were a hundred years ago. The U.S. has refined our ability to use new sources of energy that we have discovered over the last hundred years. However‚ “Annual consumption of petroleum and natural gas exceeded that of coal in 1947 and then quadrupled in a single generation. Neither before nor since has any source of energy become so dominant so quickly”
