Front

What is Earth's rotation?

Back

Earth's rotation is the spinning of the Earth on its axis, which takes approximately 24 hours to complete, resulting in day and night.

Front

What is Earth's revolution?

Back

Earth's revolution is the movement of the Earth around the Sun, which takes about 365.25 days to complete, resulting in the changing seasons.

Back

During the winter solstice, the Northern Hemisphere is tilted farthest from the Sun, resulting in the shortest day of the year.

Front

What is the significance of the poles?

Back

The North and South Poles are the points where Earth's axis of rotation meets its surface, experiencing extreme variations in daylight throughout the year.
