Rotation is the spinning of the Earth on its axis, which takes about 24 hours to complete one full turn.

Front

What is revolution?

Back

Revolution is the movement of the Earth around the Sun, taking approximately 365 days to complete one full orbit.

Front

Why do we have seasons?

Back

Seasons are caused by the tilt of the Earth's axis and its revolution around the Sun.

Front

What is the tilt of the Earth?

Back

The tilt of the Earth is approximately 23.5 degrees from vertical, which affects how sunlight is distributed across the planet.

Front

What happens during summer in the Northern Hemisphere?

Back

During summer in the Northern Hemisphere, the North Pole is tilted towards the Sun, resulting in longer days and more direct sunlight.

Front

What happens during winter in the Northern Hemisphere?

Back

During winter in the Northern Hemisphere, the North Pole is tilted away from the Sun, leading to shorter days and less direct sunlight.

Front

What is the Southern Hemisphere?

Back

The Southern Hemisphere is the half of the Earth that is south of the equator, experiencing opposite seasons to the Northern Hemisphere.

Front

What is the equator?

Back

The equator is an imaginary line that divides the Earth into the Northern and Southern Hemispheres, located at 0 degrees latitude.

Front

How does Earth's rotation affect day and night?

Back

Earth's rotation causes different parts of the planet to face the Sun or be in shadow, creating day and night.

Front

What is the significance of the solstices?

Back

Solstices mark the points in the year when the Sun reaches its highest or lowest point in the sky at noon, indicating the start of summer or winter.
