34. Put the following in order (1,2,3,4) starting with what happened first.__4__ oceans were created__2__ planets surface cooled and solidified__1__ the rain of meteors and rock bodies from space ended__3__ water vapor in the atmosphere condensed and fell as rainhttp://www.hardydrew.com/motion-graphics/9184-videohive-item-ocean-storm-150981.html#.UhQYF4zD8eE2

Match the following terms to correct phase that describes each.

Atmosphere water bodiesHydrosphere the solid part of the EarthLithosphere layer of gases around the Earthhttp://gfl.usgs.gov/AtmosphericProcesses.shtml3


The Earths geochemical cycle is the flow of chemical substances between:

a. Atmosphere b. Hydrosphere c. lithosphere http://commons.wikimedia.org/wiki/File:Ocean_Beach,_Northland,_New_Zealand.jpg537. During the development of the Earths atmosphere, the temperatures remained within a moderate range because the carbon cycle includes a natural sink - a process that removes excess carbon from the atmosphere.

Describe each stage. rainfall scrubs CO2 out of the air, producing carbonic acid (H2CO3), a weak acid. this solution reacts on contact with silicate rocks to release calcium and other cations and leave behind carbonate and bicarbonate ions dissolved in the water. This solution is washed into the oceans by rivers, and then calcium carbonate (CaCO3), also known as limestone, is precipitated in sediments. Over long time scales, oceanic crust containing limestone sediments is forced downward into Earth's mantle. Eventually, the limestone heats up and turns the limestone back into CO2, which travels back up to the surface with magma. Volcanic activity then returns CO2 to the atmosphere.739. A balance between _______________________________________________ and ____________________________________________ has kept the Earths climate stable through most of its history. 840. Why is Venus a runaway greenhouse while the Earth has fluctuated but has adjusted? 910
