Earth's Rotation and Revolution Concepts

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, 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 the cycle of day and night on Earth?

• The Earth rotating on its axis

• The Earth revolving around the Sun

• The Moon blocking the Sun's light

• The Sun moving around the Earth

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

• 12 months

• 365 days

• 30 days

• 24 hours

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

• The presence of the Moon

• 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

• Winter

• Spring

• Summer

If Earth's axis were not tilted, what would be the result?

• The Earth would not revolve around the Sun

• There would be no day and night

• There would be no seasons

• The Earth would spin faster

What is the purpose of using a globe and a lamp in the demonstration?

• To demonstrate the phases of the Moon

• To illustrate Earth's rotation and revolution

• To explain the concept of gravity

• To show the size of the Earth

How many rotations does the Earth complete in one year?

• 12

• 365

• 30

• 24

What does the demonstration with the globe and lamp show about the Sun's position?

• The Sun moves around the Earth

• The Sun is at the center of the solar system

• The Sun changes its position daily

• The Sun is closer to the Earth during summer

What is the main cause of the apparent motion of the Sun in the sky?

• The Earth's revolution

• The tilt of Earth's axis

• The Earth's rotation

• The Sun's own movement

How many other planets revolve around the Sun along with Earth?

• Seven

• Six

• Five

• Eight
