Question
9. One of the "primary" reasons why the south-westem United States still receive a cheap and abundant supply of water from distant places to irrigate crops is ? a. it is the only region in the United States where some specific types of crops will grow b. some old interstate water supply contracts from the early 1900's are still in effect c. there are no other available planting areas for crops except the south-west d. the south west has the best climate in the U.S. for growing crops e. the south western farmers are the most efficient farmers in the U.S. 10. The largest source of "accessible" freshwater for everyday human use is a. Polar ice caps (glaciers) b. reservoirs c. rivers and lakes d. groundwater e. precipitation 11. Which of the following terms below moves in a different direction from the others? a. percolation b transpiration c infiltration d. precipitation e. gravitational water 12. Read the information below and then explain the Adiabatic Process? All things being normal ! The sun heats the surface of the earth! A parcel of air near the surface will: a. rise upward, decrease in volume and increase in temperature b. creep along the ground so that the heat is evenly distributed in that area c. pretty much stay in its present location d. rise upward, expand in volume and decrease in temperature e. push downward, compress and heat the ground to make it even hotter 13. The amount of water vapor in the air, given as a percentage, at a given temperature is called a. evaporation b. relative humidity ?.condensation d, transpiration e. dew point 14 Rain Shadow areas will generally occur a. on the windward side of mountains b near active volcanic areas which release tremendous amounts of smoke, heat and water vapor c. on the leeward side of mountains d. only at the equator e. only on areas of the earth where the "Coriolis effect takes place 15 In Africa, hot humid air masses rise at the equator. Eventually these air masses fall about 25-30 degrees north and south of the equator. These areas where the air falls can be described as a. deserts b. tropical rainforests c. cold fronts d . tundra e. temperate forests 16 A Hadley Cell basically is a. a type of Fuel Cell b. a Convection Cell that moves air currents around c. a description of a Humid Area above the earth d. is a new efficient type mechanism that is currently used for the Desalinization of Water e. is afso known as a Coriolis Cell 17 A perched water-table will be found above the main water table on a layer of some material such as a clay b. sandstone c. Jones Beach type sand d. a highly fractured granite e loose grave 18. An aquifer with water that comes up to the surface under its own pressure is caliled a an unconfined aquifer because water can come up b a pressurized aquifer c a glacial aquifer d an artesian aquifer e anti-gravitational aquiferExplanation / Answer
9.A. it is the only region in the United States where some specific types of crops will grow like hay due its arid and dry conditions.
10.d. Groundwater. It is the largest potential source for accessible fresh water.
11.b. Transpiration. It is process of water evaporation from plants that means goes up. But percolation, infiltration, precipitation and gravitational water is downward movement of water.
12.d. Rise upward, expand in volume and decrease in temperature. Adiabatic process associated with orographic uplift of air parcel as it goes up and volume increases and temperature decreases due to decrease in internal energy of air parcel.
13.b.relative humidity.
14.c.on the leeward side of the mountains.
15.a. Deserts
16.a convection cell that moves air currents around.
17.a.clay.due to its weak permeability.
