Chapter 17: ● The majority of Earth's water is found in the ○ Ocean ● Several processes are involved in generating rainfall or snow. First, water is ______ from oceans and moves into the atmosphere. Next, the moisture condenses into clouds which cool and release rain or snow as ______. ○ evaporated; precipitation ● Rank the top four uses of freshwater in the U.S. from highest use to the least use. ○ Thermoelectric power ○ Irrigation ○ Public and domestic use ○ Industrial use ● Reservoirs used to produce electricity, canals used for transportation, and lakes used for recreation are examples of water with _____ uses. ○ Multiple ● If an acre of land was irrigated with 1 acre-foot of water, the water would cover the acre ______ inches deep before it soaked in. ○ 12 ● About ______ of Earth's water is found in oceans. ○ 96.5% ● Groundwater exists beneath Earth's surface as a(n) _______ rather than being chemically bonded in minerals. ○ Liquid ● Match the hydrologic cycle process with its description. ○ Evaporation ■ Water molecules rise into the atmosphere. ○ Condensation ■ Water molecules join together as they rise in the atmosphere and form clouds. ○ Precipitation ■ Clouds cool and water molecules bond together, eventually falling toward Earth. ○ Infiltration ■ Precipitation seeps into the ground surface. ● Select the two common ways in which groundwater originates and accumulates. ○ Groundwater originates from precipitation seeping into the surface where it accumulates. ● ● ● ● ● ● ● ● ● ● ● ● ● ○ Groundwater originates from snowmelt seeping into the surface where it accumulates. The three important controls of how quickly water flows through rocks are porosity of the materials, permeability of the materials, and the ______ of the water table. ○ Steepness Which of the following is not an example of a surface water application with multiple uses? ○ Water tower The water table has ______. ○ a shape similar to that of the land surface lying above ita shape similar to that of the land surface lying above it Liters, gallons, and acre-feet are three ways in which we measure the _____ of water. ○ Volume The slope of a water table is also called the ______. ○ hydraulic gradient A large body of permeable, saturated material through which groundwater can flow well enough to yield sufficient volumes of water to wells and springs is a(n) _______. ○ Aquifer The water level in a well drilled into an unconfined aquifer will be _______ the aquifer. ○ at the same level as in Surface water can soak into the subsurface and become part of the groundwater if ______. ○ the surface material is permeable ○ the water table is deep enough so there is an unsaturated zone into which the water can seep A place where water flows naturally out from rock onto the land surface is a _____. ○ Spring If you were looking for a steady supply of groundwater, you'd be looking for a(n) ______. ○ Aquifer A perched lake is above the water table. If a perched lake is to remain permanent, then the ______. ○ amount of inflow of water must be equal to or greater than the amount of outflow and losses to evaporation A well should ______ the water table in order to effectively be able to draw water to the surface. ○ intersect or be below
