Ch-3, Factors That Affect Our Climate Q.1. What do you mean by Meteorology? Ans. The study of weather conditions is known as Meteorology. Q.2. How does climate varies from place to place? Ans. a) A place is said to have a dry climate if it gets very little rain over a long period of time. b) A place is said to have wet climate if it gets heavy rainfall for many years. Q.3. Describe the factors that affect/influence the climate of a place? Ans. The factors that influence the climate of a place are: a) Distance from equator - The places near the equator are hotter because of the direct rays of the sun. Places far away from the equator are less hot because the sun rays become slanting and spread over a large area. b) Altitude or elevation Places at higher altitude have colder climate than places at lower altitude. Temperature generally decreases at 1 degree for every 100 m in altitude. c) Distance from the sea Places near the sea have a moderate climate while places far away from the sea have extreme climate. For e.g In India, Chennai is neither very hot in summer and nor very cold in winter. d) Direction of the wind The wind blowing from sea to land is cold. It is warm and dry if it blows from a warm area. e) Humidity Humidity means amount of water vapour in air. Increase in humidity causes rainfall in coastal areas and snowfall in cold areas. Q.4. Describe briefly the three climatic zones of the world. Ans. a) Torrid Zone This zone lies between Tropic of Cancer and the Tropic of Capricorn. The climate here is hot and humid. b) Temperate Zone This zone lies Tropic of Cancer to Arctic Circle and Tropic of Capricorn to Antarctic Circle. It is neither too hot nor very cold in this zone. c) Frizid Zone This zone lies between Arctic Circle and North Pole and Antarctic Circle and South Pole. The climate here is extremely cold. Q.5. Mt. Kilimanjaro in Tanzania lies near the equator but is still covered with snow. Why? Ans. It is because of its height above the sea level. Q.6. How do satellites help the meteorologists? Ans. Satellites send back pictures which tell the meteorologists about the weather all around the globe.
