ASTR 1101 Study Guide - Midterm Guide: Boiling Point, Venera 13, Supercontinent
Document Summary
Hurricanes, monsoons, water spouts, dust storms, everything. Sometimes clouds, sometimes not: movements of the water. The tides rise and fall: geologically active. Recovering the surface, adding land, mountain ranges forming, etc: energy sources. Solid iron core, surrounded by liquid iron core, rocky mantle and then crust. Think about pressure and temperature of each layer to decide which state it will be. Hot air rises and cold air falls. The mantle, even though it is rock, is plastic (not the petroleum product but as something that is malleable and can basically move- not a liquid though: this produces a convection cell but rock moves really slowly. Subduction zone: an oceanic plate slides under the continental plate. When satellites became useful, they realized that the continents are moving and apparently the shift is about 3 cm a year. Theoretically, we will all meet in the back of the planet.
