How does latitude affect global climate?

• A. Latitudes have no effect on climate.
• B. The temperatures get cooler as you move farther from the equator because the Earth's surface is curved.
• C. Elevation is the sole determinant of climate.
• D. The Sun's energy varies with latitude.

Answer: (B)

Latitude controls how directly sunlight reaches a place, which sets the amount of solar energy that region receives. Near the equator, the Sun stays high in the sky most days, so sunlight is intense and it’s spread over a smaller area, producing warmer climates. Farther from the equator, the Sun’s rays strike at a more oblique angle, spreading the same energy over a larger surface and passing through more of the atmosphere, which weakens the heating. Combined with longer or shorter days depending on the season, this reduces the average energy input and leads to cooler temperatures. The curved shape of the Earth makes this difference in solar angle across latitudes inevitable, creating the global pattern of warmer tropics and cooler poles. Other factors like elevation and ocean currents can tweak local temperatures, but latitude sets the baseline by controlling how much solar energy different regions receive.
