Unit 8: Rotation and Revolution

Front

What motion of the Earth takes 365 days?

Back

Revolution: The movement of the Earth around the Sun, which takes approximately 365 days to complete.

Front

What degree is the earth tilted?

Back

23.5 degrees: The angle at which the Earth's axis is tilted relative to its orbit around the Sun.

Front

What causes day and night?

Back

Rotation of Earth: The spinning of the Earth on its axis, which causes different parts of the Earth to face the Sun or be in shadow.

Front

What is the name of the imaginary line running through the North Pole to the South Pole?

Back

Axis: An imaginary line that the Earth rotates around, extending from the North Pole to the South Pole.

Front

What is the difference between rotation and revolution?

Back

Rotation is the spinning of the Earth on its axis, while revolution is the movement of the Earth around the Sun.

Front

How long does it take for the Earth to complete one rotation?

Back

24 hours: The time it takes for the Earth to spin once on its axis.

Front

What is the effect of the Earth's tilt on 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.

Front

What is an orbit?

Back

Orbit: The path that an object takes as it moves around another object in space, such as the Earth's path around the Sun.

Front

What is the equator?

Back

Equator: An imaginary line that divides the Earth into the Northern and Southern Hemispheres, located equidistant from the poles.

Front

What is the significance of the North Star?

Back

North Star (Polaris): A star located nearly directly above the North Pole, used for navigation as it remains in a fixed position in the sky.
