percentage of people who do not have enough water correct answer: 10% percentage of people who don't have safe water correct answer: 40% is a limited resource correct answer: freshwater linkage of marine and freshwater aquatic environments correct answer: hydrological cycle (water cycle) The continuous process by which water moves from Earth's surface to the atmosphere and back correct answer: water cycle An ecosystem where all water runoff drains into a single body of wate...

Important soil millipedes that increase aeration of top soil c. Symbiotic fungi that increase soil nutrient uptake in plant roots d. Common in soils that lack a functional humus Feedback Your answer is correct. The correct answer is: Symbiotic fungi that increase soil nutrient uptake in plant r...

Chapter 9 - APESWhere is groundwater found? within impermeable layers of rock called aquifers What is the difference between unconfined aquifers and confined aquifers? Unconfined aquifers have water flowing in and out while confined aquifers have permeable rock or clay making it hard for water to exit or enter Brainpower Read More What is a water table? the uppermost level where water in a given area fully saturates rock or soil What happens during a groundwater recharge? ...

First Law of Thermodynamics - Energy is neither created nor destroyed, but may be converted from one form to another. El Niño (ENSO) - prevailing winds in the Pacific weaken and change direction every few years which results in above average warming of eastern Pacific waters, which changes distribution of plant nutrients and alters earth's weather for 2-3 years Reason for seasons on Earth - Tilt of the axis ~23.5° Second Law of Thermodynamics - When energy is changed from one form to an...

The porosity and permeability of an aquifer define its ability to yield water to wells in productive amounts. CORRECT ANSWER-true For some wells along the coastline that are drilled into porous aquifers, pumps are turned off twice a day (during periods of high tides), since tides temporarily raise saline groundwater levels, causing saltwater intrusion into freshwater aquifers. CORRECT ANSWER-false Most wells are shallow because a significant amount of water cannot be obtained from wells wh...

APES Unit 4Where is most of Earth's freshwater found? - correct answer glaciers and icecaps Define aquifers - correct answer permeable layers of rock and sediment What is the difference between confined and unconfined aquifer? - correct answer A confined aquifer is an aquifer below the land surface that is saturated with water. Layers of impermeable material are both above and below the aquifer, causing it to be under pressure so that when the aquifer is penetrated by a well, the water wi...

APES Chapter 9Dams and Salmon on the Klamath River - correct answer hydroelectric dams, in conjunction with the drainage of two large lakes at the river's source for agriculture, impeded the flow of water and prevented the natural migration of salmon to their breeding grounds; conflict over water use between farmers, fisherman, Native Americans, industry, etc. led to overuse and exploitation of this resource and massive fish kills (increased temperatures, disease, toxic algae); the dams are sch...

Chapter 9 Questions Explain the difference between a confined and an unconfined aquifer - correct answer An unconfined aquifer is an aquifer where water can easily flow in and out. A confined aquifer has an impermeable, or confining, layer which impedes water flow to or from the aquifer What is saltwater intrusion and what causes this problem? - correct answer Saltwater intrusion occurs when saltwater mixes with freshwater and contaminates well water. It is common in coastal areas. This happ...
