Dams have a limited effect on rivers and streams. What characteristic sets streams and rivers apart? Streams have a detectable current, while rivers do not. Currents shape rivers over long periods of time.
How does current affect biodiversity in rivers and streams? It prevents bacteria and algae from living in rivers and streams. It causes a decrease in biodiversity by preventing organisms from remaining in rivers and streams. It mixes the nutrients for plant and animal use and determines location of organisms.

How do wetlands improve water quality in an ecosystem?
Wetlands can improve water quality by removing pollutants from surface waters. Three pollutant removal processes provided by wetlands are particularly important: sediment trapping, nutrient removal and chemical detoxification.

Where does the water in rivers come from what causes rivers to flow quizlet?
In the case of rivers, the water comes from precipitation that falls over mountains or hills. It flows downhill and forms tiny streams called tributaries.
How has the removal of wetlands impacted?
Wetlands destruction has increased flood and drought damage, nutrient runoff and water pollution, and shoreline erosion, and triggered a decline in wildlife populations.
What factors affect biodiversity Why do wetlands have a high level of biodiversity?
Wetlands have a high level of biodiversity because of the amount of resources available. The high levels of accessible water, nutrient levels, and primary productivity allow for a large number and variety of organisms at the base of the food web.
How does current affect biodiversity in rivers and streams A It prevents bacteria and algae from living in rivers and streams?
How does current affect biodiversity in rivers and streams? It prevents bacteria and algae from living in rivers and streams. It causes a decrease in biodiversity by preventing organisms from remaining in rivers and streams. It mixes the nutrients for plant and animal use and determines location of organisms.
How can buffer strips have a positive impact on waterways quizlet?
How can buffer strips have a positive impact on waterways? Buffer strips can decrease erosion rates, as vegetation acts as an anchor to soil. They can also decrease the amount of pollutants entering waterways by slowing runoff from agriculture and soaking up some pollutants before they enter waterways.
What is the main difference between stream pools and ponds?
Stream pools are a part of a river or creek where the movement of water is slower and there is a greater water depth. They have an easily observed current, unlike lakes and ponds.
What is the difference between a river and a stream?
Rivers are flowing water bodies that have downhill water flow and usually contain huge quantity of water. Streams are small water bodies that originate from the melting of ice on mountaintops.
Are rivers considered streams?
A stream is a body of water that flows on Earth’s surface. The word stream is often used interchangeably with river, though rivers usually describe larger streams.
What is the difference between a river and a creek?
1. A river is usually bigger than a creek although there are instances that the word creek is used for a larger body of water, depending on the place or country where it is located. 2. Rivers flow in channels and have branches or tributaries while creeks do not.
How do wetlands help reduce the damage caused by hurricanes?
Answer and Explanation: Wetlands can help reduce the damage caused by hurricanes by protecting coasts from storm surges. Storm surges are an effect from hurricanes.
How do wetlands reduce flooding and erosion?
Trees, root mats and other wetland vegetation also slow the speed of flood waters and distribute them more slowly over the floodplain. This combined water storage an braking action lowers flood heights and reduces erosion.
How do wetlands reduce flooding and erosion site 1?
Wetlands prevent flooding by temporarily storing and slowly releasing stormwater. Wetlands also reduce water flow, thus allowing sediments and associated pollutants to settle out.
How can groundwater depletion affect streams and water quality?
Some of the negative effects of ground-water depletion include increased pumping costs, deterioration of water quality, reduction of water in streams and lakes, or land subsidence. Such effects, while variable, happen to some degree with any ground-water use.
How does groundwater become polluted?
Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use. Materials from the land’s surface can move through the soil and end up in the groundwater.
Why is groundwater an important source of freshwater?
Groundwater is an important source of freshwater, partly because it accounts for approximately 30% of the Earth’s freshwater. Groundwater is an important source of freshwater for areas that do not have access to other sources of freshwater, such as areas that are experiencing droughts.
Why is wetland delineation important?
Wetland delineations must be conducted during the growing season in order to obtain accurate identification of plant species. After field work for a wetland delineation is complete, a report is then submitted to regulatory agencies.
Why are wetlands important to water quality?
Water Quality: Wetlands act as natural water purifiers, filtering sediment and absorbing many pollutants in surface waters. In some wetland systems, this cleansing function also enhances the quality of groundwater supplies.
How is wetland ecosystem important for biodiversity?
Wetlands are an important part of the ecosystem that regulate water and have a unique role in maintaining the food chain. Wetlands are also habitats for several species of wildlife, from aquatic animals to migratory birds, which lie within various ecosystems of the high mountains and lowland plains.
How do wetlands contribute to the health of the environment quizlet?
Wetlands play a vital role in the health of the environment. In addition to supporting a variety of organisms, they also reduce water erosion by trapping sediments. Wetlands help clean water by absorbing nutrients that are added to the water supply through agriculture and industry.
What characteristic is important for plants?
Plants need temperatures above freezing while they are actively growing and photosynthesizing. They also need sunlight, carbon dioxide, and water for photosynthesis. Like most other organisms, plants need oxygen for cellular respiration and minerals to buildproteins and other organic molecules.
Which of the following best describes how levees impact wetlands?
Which of the following best describes how levees impact wetlands? a. Levees protect wetlands from destructive river floods.
What is wetland farming?
Wetland agriculture is a type of farming done in the presence of a water land or near a water body. Areas as farmland. They use lands next to the water systems and to build raised farm beds. This is an intensive form of farming which requires constant care and systematic treatments.

How is water introduced into rivers and streams quizlet?
Water can be introduced into rivers and streams through surface runoff, springs, groundwater discharge, melting ice and snow, and precipitation.
