Answer 11, 12 and 13 Thank You.
D Question 11 1 pts Uranus is tilted on its side with its rotation axis almost in the plane of its orbital motion around the Sun. As a result of this the seasonal variations in temperature on Uranus are non-existent much less extreme than on Earth. about the same as on Earth since the degree to which the axis is tilted does not matter. much more extreme than on Earth.
