Answer to Exam Review Questions

Tycho Brahe is a Danish scientist and astronomer who became a primary contributor of the development of the modern astronomy . He used his own scientific methods and analysis to be able to create a basis for setting the new standard tables of astronomy . He is also the scientist who made that great discovery about the supernova lying at the Cassiopeia constellation . This leads to the start of the idea about the construction of central observatory for astronomy (Nick Greene . 2008 About .com : Space /Astronomy Sun produces

heat and light energy that are very important to us and to different organisms on earth . The sun provides light that are needed by plants to promote photosynthesis . Sun drying of different agricultural products requires the heat from the sun to remove the undesirable moisture from these products . These are only some of the examples of positive applications of sun 's energy . On the other hand , sun can also provide a great threat to humanity and other organisms due to global warming . The trapped short wave radiation of the sun can cause too much heat that can cause great climatic disturbances . Examples of these are the occurrence of hurricanes , tornados , massive heat waves and too much breakage of our polar caps in the arctic It is more likely that a solar eclipse will occur in a certain region if this is a usual path of the eclipse as predicted by the astronomers

Astronomers can determine the movement of stars whether it is moving towards or away the Earth by predicting the path or revolution of the Earth around it

One of the three theories is the Big Bang Theory which relates the beginning of the universe as a state of extreme high density that eventually expands and forms the space or the universe

It is impossible for the Jovian planets to support life since are mainly composed of gas and liquid masses . On the other hand Terrestrial planets like Earth and Mars are solids and presence of life can be more possible

Although Earth experiences more meteorite impacts than the moon . Unlike on the moon , craters on Earth made by these impacts continuously vanish due to natural processes like erosion and volcanic eruptions . Other contributors can the deposition of the soil surfaces and some tectonic activities like earthquakes (Hamilton , C .J . 2001 . Terrestrial Impact Craters .

The apparent magnitude refers to the amount of brightness of a star that is received by the Earth while the absolute magnitude describes the apparent magnitude of the star having a constant distance of 10 parsecs from the Earth . The absolute magnitude is the intrinsic property of a star (Johnson , H .L Morgan , W .W . 1953 : Astrophysical Journal , 117 313

The atmosphere is responsible for supporting human life on Earth . The atmosphere provides the oxygen for breathing and the source of carbon dioxide for plant growth . It also...
