GEOG 2050 Chapter : Chapter 5
Document Summary
Global temperatures have risen . 17* celsius every decade. We"re warming up faster than we used to, measured through a proxy. Proxy example is an ice core with air bubbles. Heat= transfer of energy from warm objects to cool objects. Sensible heat= the heat we can feel . Thermistor uses a semi conductive material senses temperature based on. High latitudes has lower annual average: altitude. 1 evaporation- consumes more of the energy arriving to earth at ocean"s. Moderates temperatures- cooler days, warmer nights: land-water heating differences surface than over land, simply because there"s water available. 84% of all evaporation on earth is from the oceans (know most all of earth"s evaporation happens over oceans) Heat energy release is the transfer from water vapor, to liquid water, to solid water. Heat energy absorbed is the transfer from solid to liquid to vapor land. Light striking soil does not penetrate the surface, but is absorbed.
