Question

use the diagram and prompt below to help you answer the next two questions.
predict how earths seasons would change if the earths tilt was increased to 45°. select the statements that describe the seasons if the earth were tilted 45°.
two images: one labeled normal 23.4 degree tilt, one labeled 45 degree tilt
(2 points)
□ the seasons would be similar to what we experience now.
□ the length of daylight during the summer would be shorter.
□ the difference between the seasons would be more extreme.
□ earths orbital path around the sun would be altered.
□ the number of days in a year would be altered.
□ the regions of the earth that experience 24 hours of sunlight during the summer would increase.
□ the number of days the poles experience 24 hours of darkness would increase.

Explanation:

• "The seasons would be similar..." is wrong as a larger tilt changes seasonality.
• "The length of daylight..." is wrong; a larger tilt would increase summer daylight.
• "The difference between the seasons..." is correct. A 45° tilt (vs 23.4°) makes summer hotter, winter colder, so seasons are more extreme.
• "Earth’s orbital path..." is wrong; tilt doesn't affect orbital path (determined by gravity, etc.).
• "The number of days in a year..." is wrong; tilt doesn't change orbital period (days/year).
• "The regions of the earth that experience 24 hours of sunlight..." is correct. A larger tilt increases the polar day (24h sunlight) region.
• "The number of days the poles experience 24 hours of darkness..." is correct. A larger tilt increases the polar night (24h darkness) duration.

Answer:

• The difference between the seasons would be more extreme.
• The regions of the earth that experience 24 hours of sunlight during the summer would increase.
• The number of days the poles experience 24 hours of darkness would increase.
