Questions and Answers

1.

How much freshwater is available today for people to use?
- A.
  
  97%
- B.
  
  3%
- C.
  
  2.2%
- D.
  
  0.6%
Correct Answer
D. 0.6%

Explanation
Only 0.6% of freshwater is available today for people to use. This means that the majority of the Earth's water is not readily accessible for human consumption. The remaining freshwater is either locked in ice caps, glaciers, or underground sources, making it difficult to access and use. This limited availability highlights the importance of conserving and managing freshwater resources to ensure a sustainable supply for future generations.

River basins and water sheds are _____.
- A.
  
  Land that drains into a river,stream, or lake
- B.
  
  Underground water resources
- C.
  
  Aquifers
- D.
  
  Another name for lakes and ponds
Correct Answer
A. Land that drains into a river,stream, or lake

Explanation
River basins and watersheds refer to the land area that is drained by a river, stream, or lake. This includes all the land, hills, and mountains that contribute water to a particular water body. The water from rainfall or snowmelt flows downhill and collects in rivers or lakes, forming a basin or watershed. This land acts as a natural drainage system, collecting and channeling water towards a common outlet. It is important to understand river basins and watersheds to manage water resources, protect water quality, and prevent flooding or droughts in a specific region.

- A.
  
  1
- B.
  
  2
- C.
  
  15
- D.
  
  17
Correct Answer

Explanation
North Carolina is known for its diverse geography and abundant water resources. The state is blessed with 17 river basins, making it rich in freshwater ecosystems. These river basins, including the Cape Fear, Neuse, and Yadkin, provide water for drinking, agriculture, and recreational activities. The large number of river basins in North Carolina highlights the importance of water management and conservation efforts in the state.

What is the definition of eutrophication?
- A.
  
  Rising and sinking of cold and warm water layers in a lake
- B.
  
  A decrease of nutrients in a lake or a pond that eventually cause the formation of a field
- C.
  
  An increase of nutrients in a lake or a pond that eventually cause the formation of a field
- D.
  
  The amount of energy it takes to raise the temperature of water
Correct Answer
C. An increase of nutrients in a lake or a pond that eventually cause the formation of a field

Explanation
Eutrophication is the process of excessive nutrient enrichment in a body of water, such as a lake or pond, which leads to an overgrowth of algae and other aquatic plants. This excessive growth can eventually cause the formation of a field, as the plants die and decompose, depleting oxygen levels in the water. This process is often caused by human activities, such as the release of agricultural or industrial runoff containing high levels of nutrients like nitrogen and phosphorus.
