Which of the following describes why wetlands are important to the water cycle?
a) dense vegetation filter out pollutants in the water
b) open meadows to filter out pollutants in the water
c) dense vegetation allows for biological magnification in the water
d) open meadows allow for biological magnification in the water

A) dense vegetation helps filter out pollutants in the water

Explanation:

The wetlands are areas that are covered with shallow waters and usually have very dense vegetation. The dense vegetation is very important as it is an excellent natural filter for the water, and the incoming polluted waters are usually easily purified in the wetlands. This is very important for the water cycle because if the water is polluted and it continues it cycle like that, then it will result in pollution on all levels in all spheres, making big environmental problems in all of the Earth's spheres.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
