Explanations:The question asks about the term that should be used to describe the condition of the atmosphere when it is hot and humid, as experienced by Rohan in Rajasthan. To understand the correct answer, it is essential to distinguish between the terms "weather" and "climate."
Weather refers to the short-term atmospheric conditions in a specific place and time. It includes various elements such as temperature, humidity, wind, precipitation, and cloud cover. Weather can change rapidly and is often described in terms of the current conditions, such as "hot and humid" or "cold and dry." In the context of the question, the immediate conditions of being hot and humid in Rajasthan are best described by the term "weather."
Climate, on the other hand, refers to the long-term average weather patterns in a region. It is a statistical description of the weather conditions over a period of time, typically 30 years or more. Climate provides a broader picture of the typical weather conditions in a place, including seasonal variations and extremes. For example, Rajasthan is known for its hot and dry climate, but this does not describe the immediate conditions experienced by Rohan.
Temperature is another term mentioned in the options, but it is only one component of weather. While temperature is an important factor in describing the atmosphere, it does not encompass the full range of atmospheric conditions, such as humidity, which are also relevant in this context.
Therefore, the correct term to describe the immediate atmospheric conditions of being hot and humid in Rajasthan is "weather." This term accurately captures the short-term and immediate nature of the atmospheric conditions described in the question.
