ConcepTest: Eccentricity and Seasons
and is replicated here as part of the SERC Pedagogic Service.
Mars has a more eccentric orbit of the Sun than Earth. Mars is 20% closer to the Sun during winter in its Northern hemisphere than it is during its summer. What would be the implications for the seasons on Earth if we had a similarly eccentric orbit with Earth being much closer to the Sun during winter in the Northern Hemisphere?a. Summer would be longer than winter in the Northern Hemisphere.
b. Winter would be longer than summer in the Northern Hemisphere.
c. The length of the seasons would not be affected.
No data yet. The correct response is A.
