<h3>What about earth's axis?</h3>
- Every 365 days, the Earth revolves once around the sun, and every 24 hours, it rotates around its axis.
- Instead of the Earth orbiting the sun, day and night are caused by the planet rotating on its axis.
- One day encompasses both daytime and nighttime and is measured by how long it takes the Earth to complete one rotation around its axis.
- The Earth rotates on its axis more slowly than it does in relation to the Sun.
- Day and darkness are caused by the Earth's rotation, while the seasons are caused by its revolution.
- The tilt of the Earth's axis is what causes the seasons.
- The Northern Hemisphere is inclined toward the sun during the summer, allowing it to receive more direct sunlight.
