Exploring the Science Behind Earth's Seasons

The video explains how Earth's orbit and axial tilt cause seasonal changes. During winter in the Northern Hemisphere, the North Pole tilts away from the Sun, resulting in shorter days and cooler temperatures. As Earth moves to spring and summer, the tilt causes longer days and warmer weather. The video also discusses how these seasonal changes affect plant life and photosynthesis, with primary producers absorbing carbon dioxide and supporting ecosystems.

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

• 10 years

• 30 days

• 24 hours

• 365 days

Why are summer days warmer and longer in the Northern Hemisphere?

• The North Pole tilts toward the Sun

• There is less cloud cover

• The Earth's orbit speeds up

• The Earth is closer to the Sun

What is the effect of Earth's tilt on the seasons?

• It stabilizes temperatures globally

• It reverses the seasons in each hemisphere

• It has no effect

• It causes longer days year-round
