Exploring Earth's Rotation and Revolution

The video explains how 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. A demonstration using a globe and lamp illustrates these concepts, showing how the Earth's movements create the illusion of the sun rising and setting.

What causes the phenomenon of day and night on Earth?

• The sun moving around the Earth

• The Earth rotating on its axis

• The moon blocking the sun

• The Earth revolving around the sun
