What is the primary cause of cooler temperatures at higher latitudes?

• A. Increased air pressure
• B. Slanted sunlight
• C. Higher elevation
• D. Ocean currents

Answer: (B)

The primary cause of cooler temperatures at higher latitudes is slanted sunlight. As one moves away from the equator toward the poles, the angle at which sunlight hits the Earth decreases, resulting in less direct sunlight and consequently less solar energy per unit area. This phenomenon causes areas at higher latitudes to receive less heat and light compared to regions closer to the equator, where sunlight strikes more directly and evenly throughout the year. The impact of slanted sunlight is significant in shaping the temperature distribution across the globe, which is why regions further north or south tend to experience cooler climates.
