Why does weather vary from day to day? Group of answer choices A. because the Sun's energy heats all parts of the Earth evenly but does not heat the atmosphere B. because weather is a complex interaction among many different variables that are constantly changing C. because the rotation of the Earth causes the atmosphere to expand and contract as it nears the Sun or Moon D. because cold fronts are always followed by a series of colder fronts, before a warm front returns

Describe the change in phase and temperature as water moves from the oceans to the atmosphere and then returns to earth again as rain. a) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature decreases b) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature increases c) evaporation : temperature decreases; condensation : temperature decreases; precipitation (rain) : temperature decreases d) evaporation : temperature increases; condensation : temperature increases; precipitation (rain) : temperature decreases
