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: -Answer is (d) the axis of rotation of the earth is tilted with respect to the plane of its orbit. Explanation: Axis of rotation of the earth is not perpendicular to the plane of its orbit. The tilt is responsible for the change of seasons on earth.
Detailed explanation-3: -Some people think that the seasons occur because of Earth’s distance from the Sun. However, Earth is closer to the Sun in December and January and farther away from the Sun in July and August.
Detailed explanation-4: -They are spring, summer, fall, and winter. The weather is different during each season. As the weather changes, plants change, too, and animals change their behavior to suit the weather.
