Answer 2

Answer:

B. I, III, and IV only

Explanation:

It is very common to have confusion between what is weather and what is climate. However, these are two different phenomena, even if they are interrelated and are influenced by the same phenomena as:

1. the cycling of water in and out of the atmosphere
2. uneven heating of the Earth by the Sun's energy
3. global patterns of atmospheric movement

On a daily basis, the weather forecast is the estimate of what is expected to occur in terms of temperature and rainfall in a short period. In this sense, the weather is constantly changing: on a certain day it can be sunny in the morning, but it can rain at night, or we can have a rainy week and a sunny week. The succession of the types of weather recorded for a given period is the climate. Thus, to define the climate more accurately, it is necessary to consider the average of the climatic variables over a long period.
