What factors are most significant in describing the climate of a region?
a. latitude and longitude
b. temperature and precipitation
c. elevation and amount of greenhouse gases
d. changes in solar radiation and milankovitch cycles

Option (B)

Explanation:

The climate refers to the long term changes that occur in terms of weather conditions. The climate of an area is mainly controlled by factors such as temperature, precipitation, atmospheric pressure, latitudinal location, the topography of the area and the elevation.

The two most significant factor that is essential in describing the climate of a particular region are the temperature and precipitation. It is important to mark the average yearly temperature as well as the temperature range that occurs in a particular area. There occurs variation in this temperature range, showing the highest and lowest temperature, in comparison to other areas.

Similarly, the average precipitation, as well as the variation in the yearly rainfall, also is equally important in order to determine the climate of an area.

Thus, the correct answer is option (B).
