Reading Answers - Earth Lakes Are Under Threat

Deprived of inflows, the sea shrank into fractured, hypersaline pools. The exposed, dry lake bed left behind vast deserts of toxic sludge. Winds routinely whip up this residual , carrying it across a 300-kilometre radius. This windborne salt poisons surrounding agricultural soils, stunts crop development, and triggers severe respiratory illnesses in local human populations.

Active restoration efforts, such as those attempted in Lake Urmia, can help restore water levels through better water allocation and management.

As lakes shrink, they expose lakebed sediments that are often contaminated with toxic heavy metals. When these dry sediments are carried by the wind, they can cause respiratory diseases and other health problems [3].

(Lakes act as carbon sinks; when they dry out, they release carbon dioxide and methane back into the air). Essential Vocabulary for This Passage

Resolving the threats facing Earth's lakes requires international cooperation and modernized environmental management.

| Question | Correct Answer | Detailed Explanation (with Evidence from Text) | | :--- | :--- | :--- | | Lake Poopo's size in summer is around ___. | 1,000 | The passage states: "With very little rainfall during summer, this reduced to around 1,000 , still a remarkable size." | | 2. The disappearance of Lake Poopo will cause a drop in the number of ___. | BIRDS | The text explains: "Environmentalists also point to the fact that the lake had been the stopover point for thousands of birds ... Their numbers will certainly fall now the lake has gone." | | 3. The Aral Sea has shrunk because water is used for crops such as rice and ___. | COTTON | The passage mentions: "Fields planted with cotton also require a regular supply" of water, which was diverted from the rivers feeding the Aral Sea. | | 4. ___ from the bottom of the Aral Sea affects agriculture 300 km away. | SALT | It says: "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 kilometres." | | 5. For families around Lake Tanganyika, fish are their only source of ___. | PROTEIN | The text states: "this decline in fish stocks has impacted on families... since they have no other source of protein ." | | 6. Around Lake Tanganyika, fisheries provide ___ to over 100,000 people. | EMPLOYMENT | The passage says: "These companies provide them with regular employment , without which communities will not survive." | | 7. Lake Urmia's color has changed because ___ are multiplying in the warm water. | BACTERIA | The text explains: "The reason for this is that bacteria quickly multiply in the warm waters of a shallow lake." | | 8. Over the last decade, ___ has declined in the area around Lake Urmia. | TOURISM | It states: "As a result, in the last decade, there has been a downturn in tourism in the area, an industry many people depended on." | When these dry sediments are carried by the

The story of the world's lakes today is one of rapid transformation and fragility. Once-vast bodies of water are disappearing or changing fundamentally due to a combination of climate change and human activity. The Disappearing Giants

The process by which water is transferred from the land to the atmosphere by evaporation from the soil and by transpiration from plants.

The passage states that even in humid tropical regions, evaporation caused by rising temperatures and human water mismanagement has outpaced any increases in precipitation, leading to a net loss.

If you’ve been following the latest environmental reports—or even if you’re just a student looking for the "Earth's lakes are under threat" reading answers—the reality is stark: we are losing our freshwater giants at an unprecedented rate. The Disappearing Acts: From Bolivia to Central Asia
