Answer

The Earth's spherical shape makes equatorial regions receive more concentrated radiation, while poles get weaker radiation. Seasonal changes occur because Earth's tilt alternates regions between direct, high-angle rays (summer) and indirect, low-angle rays (winter). Explanation 1. Earth's shape and radiation distribution Earth is spherical, causing uneven solar radiation: areas near the equator get direct rays (more concentrated, higher energy), while poles get slanted rays (spread over larger area, less energy). 2. Direct vs indirect rays and seasons Direct rays hit at high angles, producing more heat; indirect rays hit at low angles, producing less heat. Earth's tilt causes different regions to receive direct rays at different times of year, creating seasons.
