1 00:00:07,900 --> 00:00:10,980 I see a cloud! I bet that means it's about to rain. 2 00:00:11,000 --> 00:00:11,980 Whoa, whoa, whoa! 3 00:00:11,980 --> 00:00:17,980 That's a common mistake. Clouds don't just produce precipitation like rain, snow, hail, and sleet. 4 00:00:17,980 --> 00:00:21,760 We play a major role in balancing temperature and protecting life on Earth. 5 00:00:21,760 --> 00:00:27,040 I'm a cumulus cloud, a large puffy cloud that produces little to no precipitation at all. 6 00:00:27,040 --> 00:00:29,020 How do clouds balance temperature? 7 00:00:29,020 --> 00:00:34,120 During the day Earth is heated by the Sun. If skies are clear, more energy reaches the Earth's surface and 8 00:00:34,200 --> 00:00:38,740 it leads to warmer temperatures. However, if skies are cloudy some of the 9 00:00:38,750 --> 00:00:42,680 Sun's rays are reflected off the cloud droplets back into space. 10 00:00:42,680 --> 00:00:46,940 Less of the Sun's energy is able to reach the surface leading to cooler temperatures. 11 00:00:46,940 --> 00:00:49,560 Does the same thing happen at night? 12 00:00:49,820 --> 00:00:52,178 At night the opposite is true. 13 00:00:52,178 --> 00:00:58,120 The clouds are like a blanket, trapping the heat already absorbed by the surface and keeping temperatures warmer. 14 00:00:58,120 --> 00:01:03,760 But, if the sky is clear at night, heat from the surface quickly escapes into space, making temperatures cooler. 15 00:01:03,760 --> 00:01:06,180 Are all clouds the same? 16 00:01:06,180 --> 00:01:08,740 Just like people, clouds are different too. 17 00:01:08,740 --> 00:01:11,300 Clouds are classified by their appearance and by their height in the sky. 18 00:01:11,480 --> 00:01:14,820 Here are some of my friends, Cirrus and Stratus. 19 00:01:14,820 --> 00:01:15,980 Thanks, Cloudy! 20 00:01:15,980 --> 00:01:17,900 There's more to clouds than I knew. 21 00:01:17,960 --> 00:01:21,980 Clouds are so important that NASA has missions to study us. 22 00:01:21,980 --> 00:01:26,740 If you want to learn more about clouds, visit www.nasa.gov. 23 00:01:27,120 --> 00:01:27,620 Bye guys!
