Earth Science Name: Course: Date: Earth Science Describing the rock cycle The rock cycle is the process describing how rocks are formed. It describes the transition though geologic time within the three type’s of rock, igneous, sedimentary and metamorphic. Each of the three types goes through different forms within time and through different forces. The rocks are forced to change as they go through different forces that alter their equilibrium conditions. For instance, igneous rocks could weather or break down when faced with different atmospheric pressure. Thus, the cycle represents a group of changes through which rocks go through in […]

            Have youever wondered what the rocks in your back yard are made of? How about the leadin your pencil? There is a scientific field devoted to answering these types ofquestions called mineralogy. Mineralogy is the study of minerals, how they areformed, and what they are made of. There are over 4,000 different types ofminerals according to the International Mineralogical Association.  For a substance to be called a mineral it musthave five basic characteristics: The substance must be a solidIt must have a definite internal atomicstructureIt must be non-living (inorganic)It must have a chemical composition that changeswithin specified limitsIt must be […]

1-IntroductionThe atmosphere of Venus is always a difficult subject for science. The surface of Venus is the most hostile operating environment of any of the planets in  our solar system. Exploring planet Venus has been always an interesting subject for mankind. Improving understanding of Venus and its greenhouse effect atmosphere and geology has relevance to a better understanding of the Earth and solar system formation. The big problem is the high surface temperature of Venus that is approximately 452 ?C (850 F). Venus is very similar to Earth in size, initial composition, and solar radioactive influences. However, its present planetary […]

The Geographical and Geological features of Yosemite National ParkAs one of the most famous national park in the USA, The Yosemite NationalPark attracts millions of tourists every year. The reasons why Yosemite has becomethe spotlight of the world are very simple. The water, the rocks, the stunning viewand the climate of Yosemite National Valley are unique enough to attract touristsfrom all around the world. But in this paper, the main emphasis will be on the naturallandscape. Tons of tourists are visiting here just for its own unique naturallandscape. Yosemite’s natural landscape can basically be classified into twocategories and they are […]

1-IntroductionThe exploration of Venus is an important subject of study for the scientists. The Venus planet has one of the harsh environments in our solar system. Exploring planet Venus has always been an interesting subject for mankind. Improving understanding of Venus and its greenhouse effect atmosphere and geology has relevance to a better understanding of the Earth and solar system formation. The main problem is the high surface temperature of Venus that is approximately 452 ?C (850 F). Venus is very similar to Earth in size, initial composition, and solar radioactive influences. However, its present planetary conditions contrast drastically from […]

Introduction of eutrophication          Eutrophicationis the immoderate growth of aquatic plant life due to the increase of inorganicions. Plant growth is usually stimulated when the environment is rich withinorganic ions that may come from the accidental pollution by untreated sewage,run-offs containing animal waste from farmlands into lakes, river or pond andleaching of inorganic fertiliser. Apart from human and animals activities,eutrophication can occur through natural process.Causes of eutrophication          Eutrophication is mainlycaused by the immoderate use of inorganic fertiliser. These fertilisersused containing nitrate and phosphate from agricultural land will not all beabsorbed by the crops causing leaching of the fertilisers by rainwater into […]
