Exploring the Science Behind Seasons

The video explains how Earth's orbit and axial tilt cause the seasons. Earth's axis is tilted at 23.4 degrees, which affects how sunlight hits different parts of the planet throughout the year. This tilt results in varying sunlight intensity and day length, leading to seasonal changes. The video also highlights the differences in temperature between the hemispheres during different times of the year and introduces the educational series on climate science.

What is the name of the imaginary flat surface that Earth orbits on?

• Equatorial plane

• Ecliptic plane

• Galactic plane

• Orbital plane

At what angle is Earth's axis tilted?

• 45 degrees

• 0 degrees

• 23.4 degrees

• 90 degrees

How does Earth's orientation change as it orbits the Sun?

• It tilts towards the Sun

• It remains constant

• It tilts away from the Sun

• It flips upside down

What is the significance of Earth's axial tilt being 23.4 degrees?

• It affects Earth's gravity

• It defines the size of the Earth

• It determines the length of a day

• It causes the seasons

Why does Earth experience seasons?

• Due to its distance from the Sun

• Because of its axial tilt

• Due to the Moon's gravitational pull

• Because of changes in the Sun's temperature

What phenomenon is primarily responsible for the seasons?

• Solar flares

• Earth's axial tilt

• The Moon's phases

• Earth's rotation on its axis

What causes the variation in day length throughout the year?

• Earth's distance from the Sun

• The Moon's orbit around Earth

• Earth's axial tilt

• The Sun's movement across the sky
