Document Summary
An oceanic circulation pattern that drives the mixing of surface water and deep water. As it flows north, it cools and density increases so it sinks. Part of earth in which life exists including land, water, and air or atmosphere. Ice covers about 9% of land surface. Most land surfaces albedo is around 15-25% Phytoplankton draw co2 into biosphere, die & shrink to bottom of ocean (hydrosphere), forms layers of rock (lithosphere) Interaction of biosphere, atmosphere, hydrosphere, and lithosphere. Large continents have more deserts since water has to travel so far inland in dissipates before reaching middle. Rocks piles up to create mountains with rain shadows. Narrow stretch of land connecting two large land masses. Mountains prevent the other side from getting rain. Seattle gets rain but land after is dry. Instrument & historical records only go back so far. Air trapped in glacier ice (pic on canvas) Ice cores from greenland & antarctica > 2 miles (3300 m)
