Which of the following terms best describes a sustained change to weather patterns over time?

a. meteorology

b. a cold front

c. a season

d. climate change

The correct answer is D. Climate is defined as the average weather conditions in a particular location based on the average weather experienced there over 30 years or more. Climate zones with similar flora, fauna and climate are called biomes. Weather is constantly changing as temperature and humidity change in the atmosphere. It might be sunny, hot, windy or cloudy, snowing or raining. Climate refers to what is expected to happen in the atmosphere rather than the actual conditions and so it is possible for the weather to be diffident from that suggested by the climate.
