8. The three abiotic spheres are the Atmosphere, Hydrosphere and the Lithosphere. Each one of these spheres interacts with each other and the biosphere in unique and different ways. The atmosphere works with the biosphere in that it uses the gases released from living things to form itself. It also receives gases from the Lithosphere, or the earths crust to help form itself. The atmosphere helps all living things survive by keeping an oxygen rich environment and keeping out harmful rays from the sun. The lithosphere helps control the movement of heat from within the earths crust to help make it possible for life to survive. It also is part of the soil layer which is essential to plant life. The Hydrosphere is very important because it has all the water on earth. This is in the form of ice sheets, liquid or vapor, and they are all essential to the survival of living things.
12. Latitudes are the angular distance of a point on the earth that are north and south of the equator and run east and west. Parallels are the lines that connect this points running east and west and divide up the earth into equal parts. These lines help show the different climate regions of the earth. The further away from the equator you get, north and south, the colder the climate. Longitude is the angular distance of a point on the earth that is east or west from the prime meridian and runs north and south. A meridian is the line running north and south and the go from the North Pole to the South Pole. These lines converge on the poles.
13. A great circle is a circle around the whole earths circumference and it goes through the middle of the earth. There are an infinite amount of great circles that could be drawn around the earth. Great circle routes are the shortest distance between two points on earth. Meridians are only half of a great
