TOEIC・English Undergraduate almost 3 yearsago このマーカーの箇所にsvocと品詞を振るとどうなりますか? a line以外にsvocを振るとどうなるのかが特に分かりません e 10 Even in tropical regions, the climate and vegetation of mountains differ considerably from what would be considered normal for the area. Kenya's Mount Kenya, only about ten miles from the Equator, has fifteen glaciers. The windward side of a mountain usually has a much lower temperature and a much heavier rainfall than the leeward side. The leeward side is often known as a "rain way the shadow," and is a desert. Most mountains have what is called a timber line, a line above which no trees grow. Immediately below that line, even in the Torrid Zone where one would expect palm trees and tropical vegetation, the vegetation and trees are more the deciduous types of the Temperate. stupa Unresolved Answers: 1
