Groundwater
What is a cone-shaped dip in the water table that is deepest at the pipe of a well?
Cone of depression
What is a natural way to clean polluted water?
The water cycle
Which is better for fast soil formation, moist rock layers or dry rock layers?
Moist
What is the area in which the water table meets the ground's surface?
Spring
Very slowly
Give an example of a chemical pollutant.
Motor oil, gasoline, etc.
What is formed when part of a cave ceiling is left, but nothing else.
Natural bridge
What zone lies just below the water table?
Zone of saturation
What is soft water?
Water that is low in calcium and magnesium compounds
What types of pollutants occurs when warmer water around power plants can cause reduce oxygen levels in the water?
Thermal pollutants
Which rock would most likely have a cave?
Limestone
Describe the hot acid theory of cave formation.
Hot acid from deep within the earth's surface moved upward to form caves. This would make it easier for water to escape.
How much of the earth's liquid surface water is found in groundwater?
96%
What is pollution?
What happens as we add something to any resource that makes the resource no longer usable for a particular purpose and can even make it poisonous.
Describe the young-earth view on the formation of caves.
The flood had good conditions for sulfuric acid formation and for acidic water to move up through rocks.
Rainwater absorbs carbon dioxide to form weak carbonic acid. Limestone in the ground is easily dissolved by this carbonic acid. This would slowly carb out a cave. But, the water would need to go somewhere.
What are three ways to soften water?
Boiling and removing minerals in the water
Demineralization
Adding certain chemicals to the water
Where are coliform bacteria often found?
In water where manure or sewage has been dumped
How do old-earth scientists view the formation of caves?
Cave formation has always been slow
Mostly believes in the carbonic acid theory
Give three examples of landforms found in karst topography.
Sinkhole
Natural bridge
Disappearing stream
