Document Summary
When a cloud forms, it heats the air around it. The water molecules form into droplets to create clouds of condensation. Input of energy from the sun to the earth: Insolation: energy we get from the sun (uv-vis. ) Albedo 30% (0. 30) which gives 240 #* into the earth and out of the earth. During the winter, the artic circle (66 degrees north) is in the dark all day. The equator has most of the sun"s energy on average. The antarctic circle in the winter is in the sun all day. In a graph that shows the sun"s energy on the earth, there is a bump on the equator due to clouds forming. Air is heavier because it is made up of mostly nitrogen which is heavier (28) than water (18). For the water vapor, the water molecules make the vapor moist and buoyant so that it starts to rise when in warm air.
