What day is Leap Day?

• December 33

• March 32

• February 29

• January 30

Answer explanation

Every 4 years, we experience what's known as a Leap Year, where an extra day is added to the calendar: Leap Day

(February 29).

Earth takes an extra 6 hours to revolve around the sun, so 6 + 6 + 6 + 6 = 24 hours, giving us Leap Day every 4 years.

If the season is summer in the Northern Hemisphere,

what season would it be in the Southern Hemisphere?

Answer explanation

Because of the Earth's tilted axis, both hemispheres experience different seasons depending on their position, so one hemisphere is closer to the sun, while the other is further.

In the diagram, the Northern Hemisphere is closer, so is in summer. The Southern Hemisphere is further, so is in winter.

True or False:

The Earth would continue to have seasons, even if its axis wasn't tilted.

• True

• False

Answer explanation

Earth's axis is tilted 23.44°, and because of that, certain parts of the Earth are closer to the sun than others, resulting in hotter and colder temperatures and seasons.

If the Earth's axis wasn't tilted, there wouldn't be any seasons, and the climates around the world would stay the same.
