EARTH 4 Lecture Notes - Lecture 10: Cool Air, Radiant Energy, Vacuole
Document Summary
Cocolithophores harvest sunlight, coat themselves in shields made out of calcium. Oxygen goes back up in concentration in the deep ocean. Respiration going on that is driving decline, anything that dies gets eaten as it falls. Water vapor is component of atmosphere that is generally excluded. When you warm air it expands and its molecules spread, less dense, wants to go up. Cool air, wants to compress, more molecules for the same volume, higher density, goes down. Water vapor in air is a gas, displacing gas molecules, parcel with water vapor will want to go up because the molecules of water are lighter than o2 + n2 in air molecules, less mass per volume. Humid air wants to go up, moist are likes to go up. Make calcium carbonate shell and live in the surface ocean or. Equators get 12 hours of light and dark every day, not the case at the poles.
