Why Are There Seasons?

The video explains why Earth has four seasons due to its axial tilt. A long time ago, a massive impact tilted Earth, causing it to lean slightly. As Earth orbits the sun, different parts receive varying sunlight, leading to seasonal changes. When a hemisphere tilts toward the sun, it experiences summer; when it tilts away, it's winter. Spring and autumn occur in between. Seasons vary globally; when it's summer in the Northern Hemisphere, it's winter in the Southern Hemisphere, and vice versa.

What is the primary reason we experience different seasons on Earth?

• The distance of Earth from the sun changes.

• The Earth is tilted on its axis.

• The sun's energy output varies.

• The moon's gravitational pull affects Earth's climate.

What event is believed to have caused the Earth to tilt?

• The formation of the moon.

• A shift in Earth's magnetic field.

• A massive volcanic eruption.

• A large asteroid impact.

How long does it take for Earth to complete one orbit around the sun?

• One day

• One month

• One year

• One week

When the Northern Hemisphere is tilted toward the sun, what season is it there?

• Winter

• Spring

• Autumn

• Summer

Why do different parts of the world experience different seasons at the same time?

• The Earth's rotation speed varies.

• The Earth's tilt causes different sunlight exposure.

• The sun's position changes daily.

• The moon's phases affect the seasons.
