Intro to Weather and Climate (Exam 3)
You meet someone in another class who expresses skepticism about climate change and global warming. The student explains that weather in their area has been the coolest they can remember that season. Using what you've learned from the climate change chapter, select all the replies that would be accurate to share with your classmate.
-"Global warming" means that the average global temperature is increasing. It doesn't mean that temperatures everywhere are hotter. -Weather and climate are different. Cooler weather in one location does not mean the global climate is also cooler.

Which of the following statements is true?
-Altitudinal zonation makes it possible to grow many different types of crops -Altitudinal zonation strongly influences the plants (and crops) that grow there -Plants that grow well in the temperate mid-latitudes (e.g. Nebraska) can also thrive in the tropics if grown at higher elevations -Elevation plays a major role in a region's climate
