1. Which river is the hottest in the world? Icon Boiling River Icon Congo River Icon Nile River The correct answer is answer A: According to the Telegraph, the Boiling River, located deep in the Amazon rainforest, is the hottest river in the world. Locals call the river “Shanay-timpishka”, which means “boiling with the heat of the Sun”. The Boiling River is about 25 m wide and 6 m deep but only extends for about 6.4 km. The river water temperature always fluctuates from 50 to 90 degrees Celsius, sometimes up to 100 degrees, enough to cause anyone who touches it even for a few seconds to get 3rd degree burns. 2. In which country is the Boiling River located? Icon Colombia Icon Peru Icon Ecuador The correct answer is answer B: Peru, officially the Republic of Peru, is located in South America, bordered to the north by Ecuador and Colombia, to the east by Brazil, to the southeast by Bolivia, to the south by Chile and to the west by Peru. is the Pacific Ocean. The national area is about 1,285,000 square kilometers, the population is more than 32.6 million, the capital is Lima. In 2011, scientist Andrés Ruzo witnessed this river with his own eyes. Mirror reports that Mr. Ruzo has heard from him about Shanay-timpishka since he was 12 years old. According to what is said, the river was discovered by the Spaniards when they were deep in the forest looking for gold. Some of the people on the way back said that this land was dangerous, filled with poisonous water, man-eating snakes, hunger and thirst, disease, a river boiling from the bottom. He was later told by his aunt that he had seen the river. Originally studying for a PhD in geology at Southern Methodist University, Ruzo was really curious about this river. He consulted with colleagues at school, oil, gas and mining companies, all suggesting that the river is not real because the boiling rivers and lakes in the world often have a relationship with volcanoes. While the Amazon has almost no sign of any volcanoes. Despite all the disproved theories, Ruzo still decided to go deep into the forest and track down the location of the river that had cured the Ashaninka people in Mayantuyacu. The boiling river seemed to be out of the world, but Ruzo discovered it. He wrote a book about this river in 2016 called The Boiling River, Adventure and Discovery in the Amazon (roughly translated as Boiling River, adventure and discovery in the Amazon jungle) in the hope that the book will draw public attention to the real natural wonder and care to protect it against the growing threat from illegal logging. 3. Where is the hottest place on Earth with the temperature like walking on a baking pan? Icon Dasht-e Lut . Desert Icon Sahara Desert Icon Kalahari Desert The correct answer is answer A: According to Oddity Central (UK), the Dasht-e Lut desert, Persian for “empty plain”, is a large salt desert. Scientists believe that this desert region known as the “fire pan” of the Earth was formed on the seabed. Millions of years ago, the tectonic change of the sea floor rose, the water also gradually evaporated due to the increased temperature. Today, Dasht-e Lut becomes a barren land with an area of ​​​​about 51,800 km, surrounded by mountains on all sides. This prevented moist air from the Mediterranean and Arabian Seas from entering the desert, contributing to the record-breaking temperatures. The medium-resolution imaging spectrometer installed on NASA’s Aqua satellite conducted global surveys between 2003 and 2010. Collected data Data collected shows that the highest temperature ever recorded in Dasht-e Lut was 70.7 degrees Celsius in 2005. According to satellite data, this Iranian desert has the highest annual temperature in 5-7. 4. Which of the following lakes boil all year round? Icon Lake in the island of Dominica, Caribbean Icon Lake Kivu, Rwanda, Africa Icon Lake Karachay, Russia The correct answer is answer A: This is a boiling lake, located in the national park of the island of Dominica, Caribbean. This lake is 61m wide, 59m deep, the water is grayish blue. The temperature at the edge of this lake reaches about 82-92 degrees Celsius, the lake surface is often covered with a layer of white mist. Many people are curious why this lake is boiling all year round. The reason is that at the bottom of the lake there is a fountain, it can spray out many different gases such as carbon dioxide, sulfur dioxide… These gases can create bubbles up to 2-3m high, looks like the lake is boiling. In fact, the most terrible thing about this lake is not the temperature but the toxic gas. The plants and animals around the lake were greatly affected. Most of the factories have gone bankrupt and the surrounding area is uninhabited. 5. Which of the following lakes is likened to an “invisible killer lake”? Icon Lake Kivu, Rwanda, Africa Icon Blue Lagoon, Iceland Icon Lake Karachay, Russia The correct answer is answer C: This lake looks beautiful from afar, but there isn’t any living creature inside.

Icon Dallol Icon Valley of Death Icon Death Valley The correct answer is A: Dallol is the hottest place on earth, but still inhabited by the Afar people, a nomadic tribe living in portable huts. Dallol is located in the Danakil Desert Basin, a remote area in northern Ethiopia, bordering Eritrea. This is a very remote and least explored place in the world. In addition to the heat from the sun, Dallol is also subjected to heat from hot sulfur and lava lakes, making the average annual temperature here always at 34.4 degrees Celsius. 7. Where is the hottest surface temperature on Earth? Icon Dead valley Icon Lut Desert The correct answer is answer B: New research into the highest surface temperatures on Earth reveals that the Lut Desert in Iran and the Sonoran Desert in North America are hotter than Death Valley in the US. The Lut Desert holds the top spot for the world’s highest ground temperature. From 2002 to 2019, this sandy area regularly hit the highest temperature threshold, likely due to its location among the mountains, causing hot air to be trapped above the dunes, especially in areas including covered with black volcanic rock. The new findings are in line with research published in 2011 that concluded the Lut desert is one of the hottest spots on Earth. From 2004 to 2007 and 2009, the Lut Desert experienced the highest surface temperature on the planet. In 2005, preliminary data showed that the area had a temperature of up to 70.7 degrees Celsius, although the new study authors say the estimate is likely to be lower than reality. From that initial analysis, NASA announced a new version of satellite software, allowing for more accurate determination of the ground temperature on Earth. Using the updated version, the researchers were able to conclude that the temperature in the Lut Desert was in fact 10 degrees higher than previously thought. The Sonoran Desert, which lies on the border between the United States and Mexico, is similarly hot, although not as hot as the Lut desert often. The desert’s low altitude means the air is less likely to rise and cool. Result Please work harder! point
