Weather changes, every day. Climate is the weather conditions that prevail over a large, area and for a long period. The climate of a place remains more or less, the same, year after year., , b) Moderate climate and extreme climate : Places that are neither, very hot in summers nor very cold in winters have moderate climate,, Ex : Chennai, Mumbai, Cochin., , Places that are extremely hot in summers and extremely cold in winters, are said to have an extreme climate., , Why does Chennai have a moderate climate?, Chennai is near the sea coast and has a moderate climate. This is due to, the effect of sea freezes. In summer, the sea is cooler than the land., , pe, , , , , , , , Hence, air over the sea is cooler than that over the, called sea breeze, blows from sea to land, making the, winter the opposite happens and the land becomes warmer., , , , , , How do winds influence the climate of a place?, Winds have a major influence on the climate of a place. Winds, from hot regions increase the temperature, while those coming fi, cold regions decrease the temperature of the place. Sometimes, bring clouds with them and cause rainfall., , , , , , , Describe the climatic conditions of each heat zone., * The Torrid zone is hot and humid throughout the year., * The Temperate zone is neither very hot nor very cold., * The Frigid zone remains cold throughout the year., , , , , , , , How does rain occur?, , 1) The water from water bodies evaporates due to the heat of the, , 2) The water drops combine with dust particles to form clouds., , 3) The drops of water combine and become heavy and fall down as, rain., , Draw the globe and mark the heat zones., , , , , , , , North Pole, , , , North Frigid Zone, , , , , North Temperate, , , , , Torrid Zone, , , , , , , , , , , , South Pole
