Answer:
Dust bowl resulted from extreme drying and loosening of the soil that resulted in soil erosion by wind. Thus, it can be related that poor agricultural practices like over plowing , over grazing and leaving the land barren are human activities that must have contributed to the dust bowl.
Explanation:
- Dust bowl is referred to a period in early twentieth century when the the American and Canadian prairies faced severe dust storms.
- These dust storms resulted from severe drought and failure of practices to prevent soil erosion.
- Several people and livestock died as a result of choking.
- Over plowing, removal of top soil and small grasses exposed the soil to eroding winds and caused the dust storms.
Answer:
The correct option is C. Building a well between the two wells that goes deeper into the earth would not stop the water from being polluted .
Explanation:
Even if a well was constructed between the wells B and C, it wouldn't have stopped the contamination of the water. As the oil would still be leaking and it would contaminate the wells.
All of the other options can be used to stop the contamination.
Option A suggests building an impermeable membrane that would stop the oil flow. Hence, the water in the wells will not be contaminated.
Option B suggests not using the water from the wells and using an alternate water supply. The alternate water supply wouldn't be contaminated with oil.
Option D suggests chemically purifying the contaminated water. This can be an effective technique to clean the contaminated water.
Answer:
Helper.
Explanation:
I will take the position of helper that work for the betterment of environment by reducing such activities that can increase the carbondioxide concentration in the atmosphere. The main reason for this position is the destruction and damages that occurs in the environment and to organisms that are present all around the world. This global warming leads to the extinction of these species so in order to protect them I choose this position.
The answer is decomposers.
After the death of producers and consumers, decomposers (such as Actinobacteria, or other bacteria which are prokaryotes) eat that dead organisms and carbon, nitrogen, and other elements are released into the environment. It should be taken into consideration that eukaryotes (such as fungi) can be decomposers as well.
