Which climatic control affects the amount of solar heat received at a place?

Correct answer: Latitude

The direct answer is A, Latitude. Latitude means the angular position of a place north or south of the Equator. It affects the angle at which the Sun’s rays reach Earth. Step by step: near the Equator, rays are generally more direct and their energy is concentrated over a smaller area; toward the poles, rays are more slanting and spread over a larger area, so heating is generally weaker. Thus latitude helps explain differences in solar heat and temperature. Option A is correct because it controls the angle and concentration of incoming sunlight. Option B, language, is a human cultural feature and cannot change the amount of solar energy received. Option C, market, is an economic institution and has no direct role in the Sun’s angle. Option D, currency, is a system of money and also cannot affect solar heating. Other factors such as altitude, clouds and season may influence actual temperature, but among these options latitude is the relevant climatic control. Exam cue: latitude means distance north or south of the Equator; it is closely linked with solar heating.
