E&S SCI 15 Lecture Notes - Lecture 5: Effects Of High Altitude On Humans, Thermosphere, Water Cycle
Document Summary
Liquid water has high heat capacity, allows for storage and transfer of heat. Movement of heat by a water cycle that is driven by solar heating; important for climate. How energy gets here from sun; how heat lamps keep our food warm. Transfer of energy via electromagnetic radiation heats the earth"s atmosphere land, and oceans. Various substances on earth (dirt rocks water, concrete, sand, etc. ) Transfer of heat energy from one substance to another through the collision of atoms or molecules; from regions of high temperatures to low temperature. Movement of heat energy by currents (i. e. , in a fluid) Temp increases with height as radiation is increasingly abosorbed by oxygen molecules. Air pressure weight of air above an object; relates to number of molecules in a given volume and speed of the molecules. Equator absorbs more heat from the sun that it radiates away. Polar regions radiate much more heat than they absorb from the sun.
