Which statement describes the influence of latitude on temperature
The Correct Answer and Explanation is:
Correct Answer:
Latitude affects temperature because places closer to the equator receive more direct sunlight year-round, resulting in warmer temperatures, while areas farther from the equator receive less direct sunlight, leading to cooler temperatures.
Explanation
Latitude plays a critical role in determining the temperature of a region. Latitude is the distance north or south of the equator, measured in degrees. The equator is located at 0° latitude, while the poles are at 90° north and 90° south. The amount of solar energy a location receives depends largely on its latitude because of the angle at which sunlight hits the Earth.
Near the equator, sunlight strikes the Earth more directly, meaning it is more concentrated over a smaller area. As a result, these regions receive more intense solar radiation and remain warm throughout the year. This is why tropical areas near the equator, such as those in Africa, Southeast Asia, and South America, have consistently high temperatures.
In contrast, at higher latitudes—closer to the poles—the sun’s rays strike the Earth at a more slanted angle. This causes the solar energy to spread over a larger surface area and pass through more of the atmosphere, reducing its intensity. Consequently, these areas receive less heat and tend to have much cooler climates. For example, the Arctic and Antarctic regions remain cold year-round due to their high latitudes.
Moreover, latitude influences seasonal variations in temperature. Mid-latitude regions (between 30° and 60°) experience distinct seasons—summer and winter—because of the tilt of the Earth’s axis. During summer, a hemisphere is tilted toward the sun, increasing solar intensity. During winter, it is tilted away, decreasing solar input.
In summary, the farther a location is from the equator, the less direct sunlight it receives, and the cooler its average temperature tends to be. This consistent relationship makes latitude one of the most important factors in determining a region’s climate and temperature.
