Document Summary

Heat from the sun and wind patterns change with latitude. Atmosphere: layers of air around the earth. Troposphere: the layer you know, where all the weather happens. Highest = hurricane (>118 km/hr or mi/h) Jetstream - narrow, fast moving, west to east, follows wavy, unstable path. Sea breezes - wind moves from water to land, land heats up fast, air above heats up fast, now there"s low pressure, and the water that"s warming slowly. Land breezes - moves from the land, to the ocean, opposite of sea breezes. Hurricane = storm, disruptive of local atmosphere from the beaufort scale. The power of hurricanes come from hot water. As climate gets hotter, its predicted they"ll be more dangerous and more frequent. Saffir-simpson scale - category 1, 2, 3, 4, 5. Alfred wegener noticed weird patterns (like glaciers in hot places and marsupials being found here and australia) Wegener concluded that large pieces of earth"s surface moved - continental drift.
