1. Irrigation maintains moisture in the soil. Moisture is necessary for the germination of seeds. Seeds do not grow in dry soil. That is why irrigation is done before tilling.

2. Irrigation is essential for the growth of the roots of the crop plants. Roots of the plants do not grow well in dry soil.

3. Irrigation is necessary for the absorption of mineral nutrients by the plants from the soil. Thus, irrigation is essential for the general growth of the plants.

What are some theories around why the decline in violent crime rates
andreev551 [17]

Answer:

Some of the most accurate theories regarding the decline in the number of violent crimes that has taken place in recent years are the following:

-A greater presence of the government in prevention tasks, be it through the police, intelligence services or the National Security Agency itself, coordinating preventive measures to avoid this type of situation.

-An economic stability on the part of citizens, which means that they do not have to resort to crime as a means of survival, given the abundance of jobs and, therefore, the lack of economic needs on the part of individuals.

Answer:

Building B; it is around 33.29 feet taller than building A

Explanation:

Given that when things are nearer they appear bigger, hence, if the buildings have the same angular elevation from the same spot, the taller building is further away.

This is based on the fact that the hypotenuse touches the top of building A and keeps ongoing at the same angle to building B, further away.

Therefore, we have =>

tan A = ht / 40

ht A = 40 tan 59 = 66.57 ft

tan B =ht / 60

ht B = 60 tan 59 = 99.86 ft.

Therefore, 99.86ft - 66.57ft = 33.29fr

Hence, Building B is taller by 33.29
