Summary: Factors Affecting Climate

Geography is the study of persons, places, and patterns on the Earth’s surface.

My name is Musallam; I am in the 9th grade. My interests are playing golf, watching tv, and playing video games. I am looking forward to learning about the persons, places and patterns on the Earth.

As the Earth goes through its annual revolution around the sun, the suns rays fall upon the planet in a regular pattern. This pattern can be changed with zones of latitude to describe climate regions. Between 30 degrees south and 30 degrees north is a zone known as the low latitudes. This zone includes the equator, Tropic of Capricorn, and Tropic of Cancer. They receive the direct rays of the sun year-round. The Earths polar areas are called the high latitudes. When the northern or southern hemisphere is tilted towards the sun, its polar regions receive continuous sunlight. From March 21 to September 23 the Artic circle experiences continuous daylight or twilight, but the Antarctic Circle experiences daylight or twilight for the other six months. The most variable weather on Earth is found in the midlatitudes, this area has a temperate climate.

Winds occur because sunlight heats the Earths atmosphere and surface unevenly. Winds blow because of temperature differences on the Earths surface, such as the tropical air moves towards the Poles and the polar air moves towards the equator. Global winds blow in fairly constant patterns called prevailing winds. They are determined by latitude and moved by the Earths movement. The Coriolis effect causes prevailing winds to blow diagonally rather than north, south, east or west directions. At the equator global winds are diverted north and south, leaving a narrow, windless band called the doldrums. Just as wind moves, streams of water called currents move through the ocean. Climate is also affected by recurring events that alter weather patterns. The most famous of these is called El Niño. It is a periodic change in the pattern of ocean currents, water temperatures and weather in the mid-pacific region.
