Earth's Rotation & Revolution

What is the difference between Earth's rotation and revolution?

• Earth's rotation causes the Earth's orbit around the Sun, while Earth's revolution causes the Earth's spin on its axis.

• Earth's rotation causes the change of seasons, while Earth's revolution causes day and night.

• Earth's rotation causes day and night, while Earth's revolution causes seasons.

• Earth's rotation causes the tilt of the Earth's axis, while Earth's revolution causes the length of a day.

What is the significance of the tilt of Earth's axis?

• The tilt of Earth's axis has no impact on the planet

• The tilt of Earth's axis affects the rotation speed of the Earth

• The tilt of Earth's axis causes earthquakes

• The tilt of Earth's axis causes the change of seasons and influences the distribution of sunlight on Earth's surface.

Explain how the tilt of Earth's axis causes the change of seasons.

• The tilt of Earth's axis causes the change of seasons by affecting the angle at which sunlight reaches different parts of the Earth.

• The tilt of Earth's axis causes the change of seasons by impacting the ocean currents.

• The tilt of Earth's axis causes the change of seasons by influencing the strength of Earth's magnetic field.

• The tilt of Earth's axis causes the change of seasons by altering the speed of Earth's rotation.

What is the equinox and when does it occur?

• The equinox is a rare astronomical event that happens every 100 years.

• The equinox is when the sun crosses the celestial equator, making day and night approximately equal in length. It occurs around March 20th and September 22nd.

• The equinox is a mythological concept with no scientific basis.

• The equinox is when the moon is closest to the Earth, occurring in July and December.
