42 00:04:32,050 --> 00:04:36,889 Higher temperatures result in higher amount of evaporation of water from the Earth's 43 00:04:36,889 --> 00:04:40,009 surface, which causes a lot of rain. 44 00:04:40,009 --> 00:04:44,410 OK, now let's move on to the Temperate Zone. 45 00:04:44,410 --> 00:04:50,790 There are two temperate zones, one in Northern Hemisphere and one in Southern Hemisphere. 46 00:04:50,790 --> 00:04:54,670 It is the largest among all climate zones. 47 00:04:54,670 --> 00:05:00,610 The weather over here is moderate as the sun rays do not directly fall in the temperate 48 00:05:00,610 --> 00:05:02,069 zone. 49 00:05:02,069 --> 00:05:05,990 Moderate means it's neither very cold nor very hot. 50 00:05:05,990 --> 00:05:11,269 Yes, and in a few of these areas, there is year round rainfall. 51 00:05:11,269 --> 00:05:16,870 Oh, now our friend the polar bear wants to see his home, the polar zone. 52 00:05:16,870 --> 00:05:22,089 This zone is known as the polar zone as it lies close to the poles. 53 00:05:22,089 --> 00:05:27,709 There are two polar zones, one near the North Pole, above the Arctic Circle, and another 54 00:05:27,709 --> 00:05:30,050 one surrounding the South Pole. 55 00:05:30,050 --> 00:05:32,610 It is above the Antarctic Circle. 56 00:05:32,610 --> 00:05:39,209 And like our guest the polar bear told us, it is very cold over here throughout the year. 57 00:05:39,209 --> 00:05:46,189 Yes, this is because near the polar regions, the rays of sun are very slanted.
