By far most of the world's water water, respectively, constitute the third and fourth largest accumulations of water on earth. Together is im the oceins. The second largest amount is stored in ice sheets and glaciers. Ground water and soil ground water and soil water make up subsurface water. Water enters the subsurface realm through a process called infiltratiom, which is basically soaking into the ground. Subsurface water is held in and often travels slowly through cracks in rocks and in voids (spaces) between soil particles. Ground water I water does. In the ground water zone, all the available voids, cracks, and spaces are filled with water. The top of the ground water zone is known as the water table Table 7-1 97.200% 21500% 0.620% 0.005% 0002% 0.001% 0.0001% oceans ice sheets and glaciers ground water soil water fresh and salt lakes the atmosphere streams Above the water table, in the soil water zone, voids and cracks almost always contain some air as well as some water. It is in the soil water zone where most plants use their roots to take up the water that they need. After a series of storms, the voids in the soil water zone may be totally filled with water. Some of this water, however, soon drains down to the ground water zone by gravity, leaving an ideal mix of water and air for plant growth, a condition known as field capacity. Water that does not percolate down to the ground water zone will stay in the soil water zone for a while as storage from this stored soil water that plants can draw their water even if it hasn't precipitated for some time. When precipitation again allows the soil water to exceed field c (ST). It is apacity the excess amount over field drains down to the water table. This excess over field capacity is called the soil water surplus 61 GEO 121 D-G-Spring 2018Explanation / Answer
It is clearly evident from the table A and B that there is a rise in temperature from 3 to 6 degrees of farenheit during the year in lucasville in 2060 relative to current scenario.
Also it can be observed that there is loss in rainfall over the years which can be seen from precipitation values(in inches) mentioned in the Tables A and B.
Obeserving the PET values it is clearly seen that there is rise in potential evapotranspiration from the current scenerIo as compared to 2060.
