The video explains the two main motions of Earth: rotation and revolution. Rotation is the spinning of Earth on its axis, causing day and night, while revolution is Earth's orbit around the Sun. The axis is tilted, affecting the circle of illumination, which divides day and night. The video also discusses the consequences if Earth did not rotate, leading to extreme conditions unsuitable for life.

What angle does the Earth's axis make with its orbital plane?

• 45 degrees

• 60 degrees

• 90 degrees

• 66 and 1/12 degrees

What is the circle that divides day from night on the globe called?

• Circle of Light

• Circle of Darkness

Why does only half of the Earth receive light from the Sun at a time?

• Because of the Earth's elliptical shape

• Because of the Earth's spherical shape

• Because of the Earth's triangular shape

• Because of the Earth's flat shape

What would happen to the portion of the Earth facing the Sun if the Earth did not rotate?

• It would experience continuous twilight

• It would experience alternating day and night

• It would experience continuous night and cold

• It would experience continuous day and warmth

What would be the condition of the half of the Earth away from the Sun if the Earth did not rotate?

• It would be freezing cold all the time

• It would have moderate temperatures

• It would be warm all the time
