A rain garden is a garden planted in a low-lying area where water tends to collect.
What benefit would rain gardens most likely provide for a community?
A. Rain gardens slow down and filter runoff water for communities that have a lot of rain.
B. Rain gardens store rainfall so it can be used later in the year in communities with seasonal rain.
C. Rain gardens increase evaporation so there is more rain in communities with drought conditions.
D. Rain gardens remove moisture from the air so it can be used in communities with limited rainfall.
A. Rain gardens slow down and filter runoff water for communities that have a lot of rain.
The most likely benefit that rain gardens provide for a community is:
A. Rain gardens slow down and filter runoff water for communities that have a lot of rain.
Rain gardens are designed to capture and absorb rainwater, slowing down the flow of water and filtering out pollutants. This helps to prevent flooding and reduce the amount of runoff water that enters the stormwater system. By doing so, rain gardens help to improve water quality and prevent erosion in communities that experience heavy rainfall.
In order to determine the correct answer, we need to analyze the purpose and function of a rain garden. A rain garden is specifically designed to manage and control rainwater runoff in areas where water tends to collect. The primary goal of a rain garden is to slow down the flow of stormwater and allow it to be absorbed into the ground rather than being carried away by drainage systems.
Answer A states that rain gardens slow down and filter runoff water for communities that have a lot of rain. This is an accurate statement and aligns with the purpose of a rain garden. By slowing down the flow of runoff water, rain gardens help to reduce erosion, filter out pollutants, and recharge groundwater, providing numerous environmental benefits for communities that receive heavy rainfall. This answer is the most likely benefit that rain gardens provide for a community.
Answer B suggests that rain gardens store rainfall for later use in communities with seasonal rain. While it is true that rain gardens can temporarily hold and retain water after rain events, their primary function is not to store water for later use. Their main purpose is to manage rainwater runoff and prevent it from causing issues such as flooding or erosion.
Answer C states that rain gardens increase evaporation, leading to more rain in communities with drought conditions. This statement is not accurate. Rain gardens do not have the ability to increase evaporation or generate more rain. They are designed to manage existing rainwater, not create additional rainfall.
Answer D implies that rain gardens remove moisture from the air for use in communities with limited rainfall. Again, this statement is not accurate. Rain gardens do not remove moisture from the air or provide an additional water source for communities with limited rainfall.
Based on the analysis, the correct answer is A. Rain gardens slow down and filter runoff water for communities that have a lot of rain.
