Earth Rotation and Revolution Review

Front

What is Earth Rotation?

Back

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

Front

What is Earth Revolution?

Back

Earth revolution is the movement of the Earth around the Sun, which takes about 365.25 days to complete one full orbit.

Front

What causes day and night?

Back

Day and night are caused by the rotation of the Earth on its axis. When one side faces the Sun, it experiences day, while the other side experiences night.

Front

What is the tilt of the Earth?

Back

The tilt of the Earth is approximately 23.5 degrees from vertical, which affects the seasons.

Front

How does the tilt of the Earth affect the seasons?

Back

The tilt of the Earth causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the four seasons: spring, summer, autumn, and winter.

Front

What season occurs when the Northern Hemisphere is tilted away from the Sun?

Back

Winter occurs in the Northern Hemisphere when it is tilted away from the Sun.

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

What happens during the summer solstice?

Back

During the summer solstice, the Northern Hemisphere is tilted closest to the Sun, resulting in the longest day of the year.

Front

What happens during the winter solstice?

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 Earth's axis?

Back

The Earth's axis is the imaginary line around which the Earth rotates, and its tilt is responsible for the changing seasons.
