Understanding Earth's Movements and Seasons

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 movements, showing how the apparent motion of the Sun is due to Earth's movements.

What causes the cycle of day and night on Earth?

• The Sun moving around the Earth

• The Earth's revolution around the Sun

• The Earth rotating on its axis

• The Moon blocking the Sun

How long does it take for the Earth to complete one full revolution around the Sun?

• 24 hours

• 12 hours

• 30 days

• 365 days

What is the main reason for the different seasons on Earth?

• The shape of Earth's orbit

• The speed of Earth's rotation

• The tilt of Earth's axis

• The distance of Earth from the Sun

During which season does the northern hemisphere lean towards the Sun?

• Autumn

• Summer

• Spring

• Winter

What would happen if Earth's axis were not tilted?

• The Sun would not rise or set

• The Earth would stop revolving

• We would experience the same season all year

• We would have no day and night
