Earth's Tilt and Seasons Quiz

Match the following angles with their descriptions.

• The angle representing a hypothetical extreme tilt.

• Earth’s tilt is 45 degrees.

• The angle representing no tilt, resulting in no seasons.

• Earth’s tilt is 23.5 degrees.

• The angle at which Earth is tilted from its orbital plane.

• Earth’s tilt is 90 degrees.

• The angle representing a perpendicular tilt to the orbital plane.

• Earth’s tilt is 0 degrees.

What happens when you change the tilt of the Earth? (Try adjusting the tilt to see how the seasons and sunlight change.)

• When the tilt increases, the seasons become more extreme.

• When the tilt decreases, the seasons become less extreme.

• The tilt of the Earth does not affect the seasons.

• Changing the tilt affects only the length of the day, not the seasons.

• The tilt change causes the Earth to rotate faster.

What happens at the Winter Solstice in the Northern Hemisphere? (Observe the Sun’s position and the length of daylight during the winter solstice.)

• The Northern Hemisphere experiences the shortest day of the year.

• The Northern Hemisphere experiences the longest day of the year.

• The Sun is directly overhead at the Equator.

• The Northern Hemisphere experiences equal day and night lengths.

What are the equinoxes? When do they occur?

• The equinoxes occur when day and night are of equal length.

• The dates for the equinoxes are around March 21 and September 23.

• The equinoxes occur when the sun is closest to the Earth.

• The equinoxes are the longest days of the year.

• The equinoxes are the shortest nights of the year.

What happens in the Southern Hemisphere when it is summer in the Northern Hemisphere?

• In the Southern Hemisphere, it is winter.

• In the Southern Hemisphere, it is also summer.

• In the Southern Hemisphere, it is spring.

• In the Southern Hemisphere, it is autumn.

How do the lengths of daylight and darkness change as you move away from the equator? (Move different latitudes and observe how the length of day changes.)

• Near the equator, the lengths of day and night are almost equal.

• Near the poles, the lengths of day and night vary greatly.

• At the equator, there is no change in daylight throughout the year.

• Daylight increases as you move towards the poles.

• Darkness is constant at all latitudes.

The Earth’s tilt is important for life on Earth because it affects:

• The length of days and nights

• The occurrence of seasons

• The gravitational pull

• The distance from the sun
