2. Geothermal energy is thermal energy generated and stored in the Earth

3. Maga (molten) : heat solid rock surrounding the magma chamber. Then :water in porous rock above the hated solid turns to steam. can be tapped and used to rin power plants to produce electricity. For example, the Geysers in Yellowstone National Park. http://www.tudou.com/programs/vie w/w8xfHzdyLss/ It’s avaliable in onl a few spots around the world.

7. Snow monkeys living life in a geothermal hot spring.

8. 1. clean and sustainable 2. the best renewable source of energy 3.Using geothermal energy reduces acid rain by 97%. 4.help mitigate global warming if widely deployed in place of fossil fuelsglobal warming 5.heat buildings through district heating systems.

9. 1.the initial costs are too high for many nations 2. leading to closure of the electricity plant and financial losses. 3. abundance of greenhouse gases below the surface of the Earth. There can also be traces of heavy metals such as mercury, arsenic and boron. 4. requires a wide area and a massive area to lay the pipes and to build the power plant itself. 5.A well can be dug only where the layer of rocks is sitting above the hot rocks and is easy to drill through-------use of geothermal energy is hampered.

10. No.1 Fossil fuel is a hydrocarbon or its derivatives. No.2 can make large-scale industrial development and replacement of water. No.3 The source of greenhouse effect. No.4 So far, the fuel used by countries around the world almost all fossil fuels, namely oil, natural gas and coal. No.5 Looking for nature of the fossil fuels, No.6 According to the research shows that, today in the underground has no coal and oil in the formation of.

11. Fossil fuel

12. Geothermal energy Fossil fuels For environment cost effective, reliable, sustainable, and environmentally friendly Combustion of fossil fuels generates sulfuric, carbonic, and nitric acids, which fall to Earth as acid rain, impacting both natural areas and the built environment. For prices is a renewable energy source, costs effectively non-renewable, hydrocarbon supplies diminish causes high prices

13. Geothermal energy Fossil fuels applications such as home heating, opening a potential for widespread exploitation. Fuels of cars,aircrafts Raw material for industry is limited to areas near tectonic plate boundaries initial costs on it are too high for many nations Are limited to amount, because they take millions of years to form, and reserves are being depleted much faster than new ones are being made For applications Limits

14. we can think about our vacations. When we want to go to somewhere, there must have a stereotype: we'll think about if the place which chosen has a hot spot, that will be excited. So, look at this, we may suddenly realize that our mind has been contained by the hot spot. Of course, hot spot is just one part of the subterranean heat. But it has pushed the world economy as quickly as possible. Because they promote to open up someplace which used to be impoverished.
