The average temperature of the planets (A) has no relationship to the distance from the Sun
(B) decreases with greater distance from the Sun
(C) increases with greater distance from the Sun
(D) depends only on the chemical composition of the
atmosphere of each planet

B) decreases with greater distance from the Sun

Explanation:

Sun is the ultimate source of heat and light in our galaxy. The farther you get from it, the more colder you get.

it has one origin of replication, but it proceeds in two directions - d)

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
