Read the passage and answer the questions on pages 110-111. The passage is a problem-solution text about an area in Chile that has a desert climate the Atacama Desert. Clouds and Fog as a Source of Water in Chile Many of Chiles poor, northern coastal villages have suffered for years from water shortages, despite the abundance of cloud cover and fog in the region. When the cold air from the Pacific Ocean's Humboldt Current mixes with the warm coastal air, a thick, wet fog, called camanchaca by the Andes Indians, forms along with clouds (Darak, 2008). However, rather than developing into rain, the fog and clouds quickly evaporate in the hot sun. This lack of rainfall has imposed severe hardships on communities. They cannot grow crops and must carefully ration their water, which is often delivered by truck To address this problem scientists in the 1990s implemented an interesting solution on El Tofo mountain neat vllage of Chungungo. Using conventional technology, they redevised a centuries-old method to capture the water droplets of the fog in a process referred to as fog harvesting (Schemenauer and Cereceda 1991). In this method, triangular-weave polypropylene nets are attached to support posts to serve as water collectors. Each of these nets is designed to collect approximately 40 gallons of water each day. d) When the fog develops, droplets of water are trapped in the nets and join to form larger drops that then fall into a trough. From the troughs the water drains through filters into a series of underground tanks. The water is then piped to a 25,000-gallon storage tank, where it is chemically treated to kill disease-causing organisms. Finally. the water flows to individual households, just as in traditional water systems. D This collection system can supply as much as 2,500 gallons per day, enough for a small community to drink, wash, and water small gardens. The water is nat only clean, but farluss expas ve than water delivered to the area. DMore environment. lecte
