Students want to determine the impact of soil erosion from the development of new housing. They plan to measure the density of a species of algae growing along the bottom of a river that flows through their town. The town is built in a heavily forested area, but a large area of trees along the river was recently clear-cut to allow for the construction of a new housing development, which has caused exposed soil to wash into the river. The river flows north to south through the town and is still forested both up- and downstream of the town. Which of the following would be the best control sample for the study?

a. A sample of water collected just downstream of the northern forest
b. A sample of water collected just downstream of the southern forest
c. A sample of distilled water
d. A sample of water collected just downstream of the housing development

Answers

Answer 1

Considering the situation described above, the statement that would be the best control sample for the study is "a sample of water collected just downstream of the northern forest."

The students want to measure the density of algae growing along the bottom of a river that flows through their town.

And given that the river flows north to south through the town, it is ideal for controlling the sample for the study through a sample of water collected just downstream of the northern forest.

Hence, in this case, it is concluded that the correct answer is option A.

It’s D! Land formations cause linear valleys, small ponds, stream beds split in half, deep trenches, and scarps and ridges. The destructive grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.

Why is there a water shortage if two-thirds of the earth is covered my water.

Answers

Answer:

Water shortages are caused by climate change, such as altered weather patterns including droughts or floods, increased pollution, and increased human demand and overuse of water. A water crisis is a situation where the available potable, unpolluted water within a region is less than that region's demand.

Explanation:

Some places may not have access to water either. For example Nigeria don't have access to drinking water or a sanitation system for the water that is their water shortage crisis. A place may have also had a river or stream that dried up, so it's not so much of the whole world has a shortage it's more of that one or more places seperate have a water shortage.
