Document Summary

The compact, granular substance that is transition b/w snow and glacial ice. Wind lifts fine, loose sediment from the desert floor. Group that assesses and disseminates science with climate change. Today is the same as it was throughout history so we can use relative dating and numerical dating to put order to earth"s life. Form in areas where more snow is added than melts. Snowflakes become smaller, thicker and more spherical. Air is forced out of pore spaces-compaction. Snowflakes recrystallize into denser masses of small grains called firn. Under pressure, firn fuses into solid mass of interlocking ice crystals (glacial ice) Carbon moves into and out of reservoirs over both long and short time scales. When we burn fossil fuels, we combust them. Fuel reacts with oxygen to produce heat/energy. This releases trapped organic material and produces co2. How much of earth"s surface was covered by glaciers during the pleistocene. 30% - 1. 8 mya - 11,700 (ice age)
