Elevation: A Key Factor Affecting Climate — Passage and Quiz
Reading Passage: Elevation
Elevation, or the height of a location above sea level, is a key factor affecting climate. As elevation increases, the air becomes thinner and colder. This is why mountain peaks are often covered in snow, even in tropical regions.
For every 1,000 meters (3,280 feet) of elevation, the temperature drops by about 6.5°C (11.7°F). This is known as the lapse rate. For example, the city of Quito, Ecuador, located high in the Andes Mountains, has a cooler climate than nearby lowland areas.
High-elevation areas also receive more solar radiation because the atmosphere is thinner. However, the lack of air pressure at high altitudes can make it harder for humans to breathe.
Elevation also affects precipitation. Mountains often receive more rainfall on their windward side, while the leeward side remains dry, creating a rain shadow effect.
Fun fact: Mount Everest, the highest peak in the world, has temperatures as low as -60°C (-76°F)!
