Cloud Cover by Rachel Benoualid [STUDENT] https://padlet.com/rachel_308114/uw352nm26bpw Made with wonder en-us 2017-11-09 22:54:33 UTC 2017-12-08 22:42:23 UTC hello@padlet.com Cloud Cover- rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/205535774 (Yep, you guessed it) Cloud cover is  when clouds cover a section/fraction of the sky.]]> 2017-11-09 22:59:00 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/205535774 The clouds help reduce the amount of sun we get. Without cloud cover we could end up like the planet Venus. rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/205537150 2017-11-09 23:08:47 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/205537150 CLOUD COVER IS VERY IMPORTANT! rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/205537703 2017-11-09 23:12:37 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/205537703 If you think that clouds aren't needed, you have no idea what you are talking about. Without them, we couldn't survive. rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/205538126 2017-11-09 23:15:31 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/205538126 Think of clouds as a shield or a blanket. rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/206543465 2017-11-14 01:30:24 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/206543465 Clouds shield or drape over us so that some of the sun's harmful rays don't reach us. rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/206545305 2017-11-14 01:40:54 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/206545305 When there isn't any cloud cover, it is called a clear sky. This is when 0 to 1/10 of the sky has clouds. rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/207019012 2017-11-15 01:05:38 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/207019012 The sun's rays bounce off of the clouds. rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/207020180 2017-11-15 01:11:01 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/207020180 Some heat passes through the clouds, warming the ground. rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/207020358 2017-11-15 01:12:06 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/207020358 Other rays get trapped beneath the clouds, and continue bouncing between the clouds and the ground. This creates the greenhouse effect. The rays insulate (heat) the ground. rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/207020382 2017-11-15 01:12:16 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/207020382 Why are clouds white? As "light passes through a cloud it interacts with larger water droplets which scatter all colors of the spectrum of light almost equally. This means that the sunlight continues to remain white making the clouds appear white"(Met Office). rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/207483808 2017-11-16 00:30:07 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/207483808 Why can clouds block the sun/radiation? rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/207484937 Clouds reflect radiation. If a cloud will heat or cool a surface depends on its altitude, size, and the particles that form the cloud. The cloud reflects more short-wave radiation back to space than the surface would if the cloud wasn't there. In turn, it leaves less solar radiation to heat the atmosphere and surface. Clouds have the ability to absorb some of the heat.]]> 2017-11-16 00:36:36 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/207484937 Why do I need sunscreen on a cloudy day? rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/207485414 Even though the sky may appear to be cloudy, some of the sun's rays are able to pass through the "cloud barrier". Make sure you still wear sunscreen on a cloudy day!]]> 2017-11-16 00:38:59 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/207485414 rachel_308114 https://padlet.com/rachel_308114/uw352nm26bpw/wish/207487508 2017-11-16 00:51:39 UTC https://padlet.com/rachel_308114/uw352nm26bpw/wish/207487508
