Earth's rotation and revolution

What is the difference between rotation and revolution?

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

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

• Rotation refers to the tilt of the Earth, while revolution refers to the orbit of the Moon around the Earth.

• Rotation is the circular motion of the Earth, while revolution is the linear motion of the Earth.

What causes day and night on Earth?

• Earth's rotation on its axis causes day and night.

• The distance of Earth from the Sun causes day and night.

• The tilt of Earth's axis causes day and night.

• The phases of the Moon cause day and night.

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

• 12 hours

• 24 hours

• 36 hours

• 48 hours

How long does it take for Earth to revolve around the Sun?

• Approximately 365 days

• Approximately 365 1/4 days

• Approximately 360 days

• Approximately 366 days

What is the term for the path Earth takes around the Sun?

• Orbit

• Revolution

• Rotation

• Trajectory

Why do we have leap years?

• Leap years are added to keep our calendar in alignment with Earth's revolutions around the Sun, accounting for the extra 1/4 day each year.

• Leap years are necessary to celebrate New Year's Day every four years.

• Leap years are introduced to make up for the lost time due to daylight saving changes.

• Leap years are used to synchronize the lunar calendar with the solar calendar.

What is the effect of Earth's tilt on seasons?

• Earth's tilt causes the changing seasons as different parts of the Earth receive varying amounts of sunlight throughout the year.

• Earth's tilt has no effect on the seasons.

• Earth's tilt only affects the temperature, not the seasons.

• Earth's tilt causes the same amount of sunlight to reach all parts of the Earth throughout the year.

What are the two main effects of Earth's rotation?

• The occurrence of day and night and the apparent movement of the Sun across the sky.

• The changing of seasons and the formation of tides.

• The creation of weather patterns and the shifting of tectonic plates.

• The increase in temperature and the reduction of atmospheric pressure.

What is high tide caused by?

• The gravitational pull of the Moon and the Sun on Earth's oceans.

• The rotation of the Earth on its axis.

• The wind patterns over the ocean surface.

• The melting of polar ice caps.

What is the significance of the Earth's tilt?

• It determines the shape of the Earth.

• It affects the intensity and duration of sunlight received at different latitudes, influencing climate and seasons.

• It controls the rotation speed of the Earth.

• It has no significant impact on the environment.
