Geography Homework Assignment The three main abiotic spheres that make up the Earth system are atmosphere, hydrosphere and lithosphere. 2. A. The various latitudinal geographical zones that roughly subdivide Earth’s surface are five climatic zones: the Arctic Circle (North Frigid Zone), the Tropic of Cancer (North Temperate Zone), the Equator (Torrid Zone), the Tropic of Capricorn (South Temperate Zone), the Antarctic Circle (South Frigid Zone).B. Sault Ste. Marie, Ontario is located in the North Temperature Zone (Tropic of Cancer).3. Prime Meridian (or Greenwich) is the meridian which serves as the beginning for all longitudes’ account.

It passes the Royal Observatory Greenwich, London and defines the Earth on Eastern and Western Hemispheres. Prime Meridian was accepted by 41 delegates from 25 countries in October 1884 in Washington, U.S. where the International Meridian Conference was held. 4. As a city is located at latitude 500 N and the Equator is latitude 00, and one degree of latitude is 111km, a city is 5550km far from the Equator.5. As city A is located at latitude 580 N and city B is located at latitude 100 S, city A is (58+10)*111=7548 (km) far from city B.6. As a search and rescue team based at latitude 250 N was called to an emergency at latitude 550 N, it should cover (55-25)*111=3330 (km) to reach the emergency site. 7. As a search and rescue team from the longitude 350 W was called to an emergency occurred at longitude 250 E, it needs to travel 600 to reach the emergency site.8. The time at longitude 800 E should be ahead of the time at longitude 200 E because from the Prime Meridian’s time longitude 00 goes ahead on East.

Meridians conventionally define the Earth’s 24 different time zones (one zone per hour) according to number of hours which the Earth needs to go around its axis, so while the Earth is already fully insolated at longitude 800, at longitude 200 E is still morning.
