Detailed explanation-1: -Earth’s tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun’s most direct rays. So, when the North Pole tilts toward the Sun, it’s summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it’s winter in the Northern Hemisphere.
Detailed explanation-2: -It’s warmer in summer than in the winter because of Earth’s consistent tilt. When the North Pole tilts toward the Sun (position 1 in Earth’s orbit), the entire Northern Hemisphere receives more direct sunlight (solar radiation), and that hemisphere experiences warmer temperatures (summer).
Detailed explanation-3: -Due to Earth’s rotation and tilted axis, the Sun’s rays strike the Earth at different angles throughout the day. This leads to the weather of different locations on Earth to be different.
