The video explains the concepts of Earth's rotation and revolution. Earth's rotation on its axis causes day and night, while its revolution around the Sun leads to the changing seasons. The Earth's axis is tilted, which results in different parts of the planet receiving varying amounts of sunlight throughout the year, creating seasons. A demonstration using a globe and lamp illustrates these concepts, showing how the Earth's movements affect our perception of the Sun's motion.

What causes day and night on Earth?

• The Sun moving around the Earth

• The Earth spinning on its axis

• The Earth moving closer and further from the Sun

• The Moon blocking the Sun
