Which of the following is a true statement about weather and climate maps

a. climate maps change everyday.

b. weather maps covers long periods of time.

c. climates maps use years of data collected over time.

d. weather maps do not contain daily temperature ranges.

Your answer is 
C. Climate maps use years of data collected over time. 

To explain this answer, we can simply explain why the other statements are false. Keep in mind the difference between climate and weather:
Weather =  day to day conditions within any given area
Climate = an "average" of these daily weather conditions over long periods of time

With that in mind, go over the answer choices:
A. Climate maps change everyday
We said that climate is an average of weather conditions over long periods of time, therefore they cannot change on a day to day basis. 

B. Weather maps cover long periods of time. 
Weather maps, based on the definition of weather itself, are day to day occurances, and can change often. For example, it can rain one day, but be completely sunny the next. It is difficult to predict weather far in advance. There, it cannot cover long periods of time. 

C. Climate maps use years of data collect over time
This is true. Climate is an average of weather patterns over long periods of time. 

D. Weather maps do not contain daily temperature ranges
Actually, they do. Again, weather is on a day to day basis, so therefore, they must contain daily temperature ranges.
