5. the earth's surface is approximately 71% water and 29% land. a. following the approach shown in class from the energy balance over land and oceans: an assessment based on direct observations and cmip5 climate models," estimate the fraction of the water vapor in the atmosphere (land +ocean) that originates from land surfaces vs oceans seas b. land surfaces receive on average 0.72 m of precipitation per year. estimate the fraction of the 0.72 m of precipitation on land that originates in the seas. can you think of any other hydrologic components that should be approximately equal to this estimate?

explanation:

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
