What Is the Difference in Temperature Between the Equator and the Poles

Multiple Choice

What is the difference in temperature between the equator and the poles on Venus?

A) large but less than on Earth, because a very dense atmosphere on Venus conducts heat more efficiently than does our own atmosphere
B) almost none, because of a very efficient pattern of circulation in Venus's atmosphere
C) much larger than on Earth, because Venus lacks an ocean. On Earth, ocean currents such as the Gulf Stream transport heat from the equator to the poles.
D) extreme, because of a lack of any appreciable atmosphere on Venus results in extreme solar heating at the equator and uninhibited heat loss at the poles
