ERS103H5 Midterm: ERS TT1 Study Guide
Document Summary
Uneven heat distribution result in heat moving polewards via winds. Warm moist air rises at the equator due to evaporation, causing a low pressure system. Water vapor forms clouds, clouds move polewards, air cools and turns to precipitation. Cold, dry air causes high pressure systems as it descends. Ocean circulation driven, in part, by atmospheric circulation. Ocean holds far more heat than the atmosphere. A proposed global circulation driven by sinking of cold, salty water in the. Whatever cause is changing a situation, it creates a positive response, an increased response. A regulatory mechanism in which a "stimulus" causes an opposite "output" in order to maintain an ideal level of whatever is being regulated. Sedimentary layers are deposited in a time sequence, with the oldest on the bottom and the youngest on the top. Layers of sediment are originally deposited horizontally under the action of gravity.
