Document Summary
Differs from other physical and natural sciences cuz of water and salt (geology, chemistry, biology, evolution, physics all in ocean) In indonesia, research marine life with boxes to see beneath waves. Published on coral reefs, theory about atolls form. Challenger expedition systemically sampled water column used new tools to study diversity. Steel ball on cable going down into ocean. Important cuz people believed no life below where no light. Aqualung = first self-contained under water breathing apparatus. 70% earth is ocean (97. 5% water of earth) Structure of planet is critical to understanding the oceans. Egg shells 3x thicker than crust in ratio. Dense sinks> mantle heats so rise> cools and falls but in a circle cuz under cooling mantle is warmer mantle (that"s rising) Creating a convection cell (a warmer fluid floats and sinks when cool) Convection cell creates friction under plates so plates move. Plates move apart and magma goes up cooling into new crust.
