Exploring Earth's Rotation and Revolution

The video explains the two main motions of Earth: rotation and revolution. Earth's rotation is the spinning on its axis, taking approximately 24 hours, resulting in day and night. The rotation direction is counterclockwise, causing the Sun to rise in the east and set in the west. Evidence for rotation includes star trails and Foucault's pendulum. Earth's revolution is its orbit around the Sun, taking about 365.25 days, defining a year. The revolution is also counterclockwise. The video concludes with a summary of these concepts.

What is the term used to describe the spinning of the Earth on its axis?

• Precession

• Revolution

• Rotation

• Orbit

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

• 12 hours

• 48 hours

• 24 hours

• 72 hours

In which direction does the Earth rotate?

• South to North

• North to South

• West to East

• East to West

Why does the Sun appear to rise in the east and set in the west?

• Because the Earth rotates from east to west

• Because the Earth rotates from west to east

• Because the Sun rotates around its axis

• Because the Sun moves around the Earth
