If our year were twice as long (that is, if Earth took twice as many days to complete each orbit around the Sun), but Earth's rotation period and axis tilt were unchanged, then .
A)the Earth would not have seasons
B)the cycle of precession would take 13,000 years instead of 26,000 years
C)the four seasons would each be twice as long as they are now
D)stars would take twice as long to rise and set

Question

Quizplus · Accepted Answer

The four seasons are determined by the tilt of Earth's axis, which would remain unchanged in this scenario. Therefore, with a longer year, each season would be twice as long. Option A is incorrect because seasons are determined by the tilt of the axis, not the length of the year. Option B is also incorrect because the cycle of precession is determined by the gravity of the Sun and Moon on Earth's bulge, not the length of the year. Option D is not affected by the length of the year, as the speed of Earth's rotation remains the same.
