Answer:
Human activities cause erosion in a number of ways across the globe. Research has shown that humans are responsible for more erosion than natural processes.
1. Deforestation - it drastically causes an increase in the erosion rates as plant roots hold soil tightly that prevent erosion due to wind and water but cutting trees increases it. Plantation reduces erosions.
2. Agricultural practices have an impact on erosion rate. This promotes the likelihood of erosion, as the soil can be transported more easily due to wind and water.
3. Growing monocultures - one type of crop leads to an increase in erosion as nutrition and components of soil are drastically reduced. r
4. chemical fertilizers in agriculture can also increase soil erosion, as these chemicals damage, the flora, and fauna that live in the soil.
5. Mining/walking or biking and other practices can also contribute to erosion gradually over time. Mining exposed soil during this process.
What time period are we talking about here?
Answer:
b. difference threshold
Explanation:
In psychology, the difference threshold, also known as<em> just noticeable difference</em>, refers to the slightest difference between two stimulations that an individual is able to detect. These stimuli could be, for example, a small difference in the weight or size of two objects, a slight difference in sounds, etc.
In this case, a person is asked to listen to a series of tones presented in pairs, and asked to say whether the tones in each pair are the same or different in pitch. Therefore, the researcher is most likely measuring the individual's <u>difference threshold</u>.
B. Calculating the cost of time, energy, and sacrifice.
Answer: Equity.
Explanation: The Theory of Equity is the belief that rewards should be proportionate to the effort and equal for all, demonstrating harmony and balance. Usually attributed to J. Stacy Adams, there are major types of references that people always compare their efforts and rewards with.
