Answer to Question 1

It is not necessary to visit the world's polar regions. Because temperature decreases with altitude, climate changes experienced when climbing 300 m (1000 ft) in elevation are about equivalent in high latitudes to horizontal changes experienced when traveling 300 km (186 mi) northward (a distance equal to 3 latitude). Moreover, as air rises along the windward side of a mountain, precipitation amounts usually increase the higher you go. Therefore, when ascending a high mountain, once can travel through many climatic regions in a relatively short distance. Thus, highland climates can show a great deal of variation in temperature, precipitation, and vegetation over a relatively short vertical change in elevation, which can be compared to environments found at the North and South Poles.
