Earth Lakes Are Under Threat Reading Answers _top_ Jun 2026

🌍💧

Lakes hold over 80% of the world’s liquid surface freshwater. They support critical ecosystems, provide drinking water, and regulate local climates. However, recent environmental studies reveal a troubling reality: more than half of the world's large lakes are drying up.

Lake Poopo is not the only vast area of water to have disappeared. The in Central Asia was once the world's fourth largest lake but then it began to shrink in the 1960s. As a shallow lake, it depended on rivers to keep its level up. But then water from these rivers was diverted for irrigation purposes. Rice is a crop that needs huge quantities of water to survive in desert areas. Fields planted with cotton also require a regular supply. Now the water level is so low that fishing has stopped altogether. And it is not just the immediate area that is affected. Because the floor of the lake is now exposed, the salt that lies there is often carried by the wind across a radius of 300 kilometers. This impacts on agriculture as it damages growing plants and is absorbed by the soil.

Answer: FALSE (or NO )

Rising temperatures are dramatically affecting lake health. Warmer air increases evaporation rates directly from the water surface [1, 2]. Furthermore, warmer water holds less oxygen, which can cause "dead zones" where fish and other aquatic life cannot survive.

The passage "Earth’s Lakes Are Under Threat" generally employs three main question formats. 1. Paragraph Matching / Locating Information

Since 1985, the average surface water temperature of the world's lakes has increased by 0.34°C every ten years. Some lakes, like Lake Fracksjon in Sweden, are warming even faster, with an increase of 1.35°C per decade. earth lakes are under threat reading answers

Major threats

Lakes worldwide are shrinking and losing water quality at an unprecedented rate. Satellite data reveals that more than half of the world's large lakes have lost significant water volume over the past three decades. This decline threatens the primary water source for billions of people. Paragraph B: The Impact of Climate Change

Satellite imagery shows that over [50% / half] of large global lakes have lost water volume. 🌍💧 Lakes hold over 80% of the world’s

Pollution is a mounting, pervasive threat to the world's lakes. It enters the water from a range of sources, primarily:

The passage emphasizes that restoration efforts are rare, expensive, and largely unsuccessful so far, with many reservoirs continuing to shrink.

Explanation: The passage highlights economic devastation, noting that fish die-offs have bankrupt local fisheries and forced massive human migration, proving adaptation was not successful. Lake Poopo is not the only vast area

Human demand for irrigation and drinking water is literally draining lakes. The Aral Sea (a saline lake) has shrunk to 10% of its original volume. More recently, Lake Poopó in Bolivia disappeared entirely in 2015 due to mining diversions and drought. The Caspian Sea, Earth’s largest inland body of water, is currently dropping by 7 centimeters per year.
