Midway between these two times, in spring and autumn, the spin axis of the earth points 90 degrees away from the sun.
What are the two main causes of changing seasons?
Remind students that the two reasons seasons occur are the tilt of a planet’s axis and its orbit around the sun . Ask: A planet’s axis might have a smaller or larger tilt than Earth’s.
What are the causes of seasonal change?
The Short Answer:
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.

- Earth’s rotation and inclination of its axis.
What causes change in seasons for kids?
Seasons are caused because of the Earth’s changing relationship to the Sun . The Earth travels around the Sun, called an orbit, once a year or every 365 days. As the Earth orbits the Sun, the amount of sunlight each location on the planet gets every day changes slightly. This change causes the seasons.

How does the tilt of Earth affect sunlight?
The tilt of the Earth’s axis also defines the length of daylight . Daylight hours are shortest in each hemisphere’s winter. Between summer and winter solstice, the number of daylight hours decreases, and the rate of decrease is larger the higher the latitude. The fewer sunlight hours the colder the nights.
How do seasons change on Earth?
The Short Answer:
Earth has seasons because its axis is tilted . Earth’s axis is always pointed in the same direction, so different parts of Earth get the Sun’s direct rays throughout the year. For example, in summer, the Sun’s rays hit that region more directly than at any other time of the year.
What would happen if seasons don’t change?
season changes on earth due to revolution of earth around the sun and due the tilted axis. Explanation: If the seasons didn’t changed this will result in the axis being not tilted . This will result in extremely cold climate near the poles and extremely hot climate near the equator.
