The difference between the hottest and coldest months of a place is the

The question is asking you to identify the term that describes the difference between the hottest and coldest months of a place. The correct answer is the annual range temperature.

The annual range of temperature is a term used in climatology, and it refers to the difference between the highest temperature and the lowest temperature observed in a particular place over the course of a year. This is a key parameter in understanding the climate of a location, as it gives us insight into the extent of seasonal variation in the weather.

Option A, the length of the hot season, does not accurately describe the difference between the hottest and coldest months as it refers more to the duration of high temperatures rather than the difference in temperatures.

Option B, the mean annual temperature, refers to the average temperature over a year, but it doesn't indicate the difference between the hottest and coldest temperatures.

Option D, the total monthly temperature, is also incorrect as this concept does not exist in climatology. It could potentially refer to the sum of daily temperatures in a month, but this is not related to the difference between the hottest and coldest months.
