If you can provide the exact reading passage or the questions you’re working on, I can give you the precise answers. Otherwise, the above covers the most common answers for a passage titled “Earth’s Lakes Are Under Threat.”
Lakes and reservoirs, which hold 90% of Earth's surface freshwater, are declining at an unprecedented rate. The primary drivers of this crisis are climate change, unsustainable irrigation, and industrial pollution. These environmental shifts have led to the total disappearance of some lakes and severe ecosystem disruption in others, impacting the food security and livelihoods of millions. Key Threats and Causes
Climate Change: Rising global temperatures have caused average lake surface waters to increase by 0.34∘C0.34 raised to the composed with power C per decade since 1985.
Irrigation Projects: Diversion of river water for thirsty crops like cotton and rice has drained major water bodies.
Pollution & Industry: Local mining industries and agricultural runoff (fertilizers) contaminate remaining water, leading to toxic algal blooms and bacterial growth.
Physical Engineering: The construction of dams has further restricted natural water flow into terminal lakes. Case Studies: Lakes in Crisis Key Findings Lake Poopó Completely dried up in 2015. It formerly covered in the dry season. Loss of habitat for migratory birds. Central Asia
Shrunk dramatically due to irrigation. Exposed salt from the lake floor is carried up to 300km by wind, damaging surrounding agriculture. Lake Tanganyika East Africa
Warming has disrupted the ecosystem, causing fish stocks to drop. This removes the primary source of protein for local families. Lake Urmia
Waters have turned red due to increasing bacteria in shallow, warm conditions. Tourism has declined over the last decade. Lake Fracksjön earth lakes are under threat reading answers
Identified as an extreme example of warming, with an increase of 1.35∘C1.35 raised to the composed with power C per decade. Reading Comprehension Answer Key

Title: The Vanishing Mirrors
The reading comprehension passage was titled "Earth Lakes Are Under Threat," but for Elara, it wasn't a textbook subject. It was the view from her kitchen window.
For generations, the town of Oakhaven had been defined by the silhouette of Lake Serene on the horizon. It was a massive, glittering sheet of blue that reflected the sky like a mirror. But lately, the mirror was cracking.
Elara, a hydrologist, sat at her desk late one Tuesday night, grading papers. She sighed, picking up a student’s answer sheet. The prompt had asked for the primary causes of freshwater degradation. The student had scribbled: “Pollution and hot weather.”
It was reductive, yet painfully accurate for her hometown. She looked out the window. The "hot weather" part was visible in the receding shoreline, leaving a bathtub ring of dried mud and exposed roots. The "pollution" was visible in the thick, neon-green algae blooms that choked the swimming coves.
The next morning, the town council convened an emergency meeting. The reading answers from the scientific community had finally trickled down to the local government, and the mood in the hall was grim. Mayor Higgins stood at the podium, looking older than he had a month ago.
"Folks," Higgins said, his voice amplified by the crackling microphone. "The reports are in. We can no longer treat Lake Serene as an infinite resource. The water levels are at forty percent capacity. The phosphate levels are toxic."
Elara stood at the back of the room. She watched her neighbors shift in their folding chairs. These were people who had fished in these waters for decades, who had taught their children to swim off the wooden docks that now sat uselessly on dry land. | Word | Definition | Example from Text
"We have two choices," the Mayor continued. "Strict rationing, or we lose the lake entirely within five years."
A man in the front row stood up—it was Mr. Henderson, who owned the local marina. "You're killing this town," he shouted. "If we ration water, the tourists stop coming. If the tourists stop coming, we die anyway. The lake has survived droughts before."
Elara stepped forward. "Not like this, Mr. Henderson," she said, her voice calm but firm. "The study I submitted last week—the answers you’re looking for—aren't just about the rain. It's the runoff. The fertilizers from the farms north of us, combined with the rising temperatures, are turning the lake into a petri dish. We aren't just losing water volume; we're losing oxygen. The fish are already dying."
The room fell silent. The threat had moved from a hypothetical future to a present reality. The "reading answers" they had all ignored in scientific journals were now dictating their livelihoods.
The debate raged for hours. It was a classic tragedy of the commons—everyone wanted the lake saved, but no one wanted to pay the cost of saving it. The farmers argued for their crops; the tourism board argued for the economy; the residents argued for their lawns.
Finally, Elara walked to the front of the room. She placed a glass jar on the podium. Inside was murky, greenish water, taken from the lake that morning.
"This is what we're drinking," she said. "This is the answer. The threat isn't just that the lake might disappear. The threat is that it’s changing into something that can’t sustain life. If we don't act now, we won't have a drought problem. We’ll have a toxicity problem."
She looked at the faces of her neighbors. The denial was draining out of them, replaced by a cold fear.
In the weeks that followed, Oakhaven changed. It wasn't a miraculous turnaround; it was a grueling, grinding effort. The reading answers from the scientists became a roadmap for survival. Strict bans on phosphate fertilizers were enforced. Water usage was capped. The local college launched a massive cleanup initiative to dredge the algae.
Elara watched the sunset over the lake a year later. The water level was still low, the scars of the drought visible on the banks. But the neon-green sludge had receded. The water was clearing. If you have a specific reading text, here’s
She picked up a new stack of papers from her students. This time, the answers were different. The students wrote about sustainability, about ecosystems, and about stewardship.
The lake was still under threat, and it would be for years to come. But the greatest threat—ignorance—had finally been washed away. The mirror was broken, but they were finally learning how to piece it back together.

Lakes act as natural reservoirs, capturing rainfall and snowmelt. They serve as critical buffers against droughts, support inland fisheries that feed 200 million people, and host biodiversity hotspots. For example, Lake Malawi contains more species of fish than any other lake on Earth. Yet, unlike oceans, lakes have limited exchange with external systems; pollution trapped in a lake often remains there for decades.
