B, provide systematic irrigation.
The correct answer is - (1) rising expanding cooling condensation.
At first there's the evaporation of water, since the water vapor is less dense than the air it rises up and starts to expend as it goes further upwards in the atmosphere. Once it reaches the upper layers of the troposphere than the cooling process starts because the temperature is decreasing with the altitude. Because of the cooling the process of condensation will start taking place and thus the formation of clouds were the water vapor returns to liquid form and creates rain. The cycle repeats its self all the time.
Answer: 4
Explanation:
Assuming the formula was meant to be:
7x + 3 = 3x + 20
X will be:
7x + 3 = 3x + 20
7x - 3x = 20 - 3
4x = 17
x = 17/4
x = 4.25
x = 4
I believe it is fall in the north and spring in the south
