Question

Why does weather vary from day to day?

A. because weather is a complex interaction among many different variables that are constantly changing

B. because cold fronts are always followed by a series of colder fronts, before a warm front returns

C. because the Sun's energy heats all parts of the Earth evenly but does not heat the atmosphere

D. because the rotation of the Earth causes the atmosphere to expand and contract as it nears the Sun or Moon

Answer 1

A

Step-by-step explanation:

D is not correct because the atmosphere doesn't expand, C isn't correct because the Sun doesn't heat all the Earth evenly (hence different climates), B is not correct because cold fronts can be singular, so it has to be A
