4 . Four Places Named After Scientists in Antarctica
There are many scientific breakthroughs made by women in Antarctic. Here are four landmarks in Antarctica and the female pioneers they’re named for.
Jones Terrace (梯田)
The ice-free terrace in eastern Antarctica’s Victoria Land bears Jones’ name. In 1969, geochemist Lois M. Jones led the first all-female research team from the U.S. to work in Antarctica. Jones and her team studied chemical weathering in the McMurdo Dry Valleys, an ice-free area of Antarctica. Through chemical analyses of rocks they had collected, Jones and her team discovered many geochemical characteristics of the valley’s ice-covered lakes.
Mount Fiennes
8,202-foot-high Mount Fiennes, located on Antarctica’s largest island — Alexander Island — is named for Ginny Fiennes. She established and maintained 80-foot-tall radio towers in the Antarctic. In 1985, Fiennes became the first female who was invited to join the Antarctic Club, a British supper club open to individuals who have spent extended time in the Antarctic region.
Francis Peak
The 3,727-foot-tall peak on Antarctica’s Adelaide Island is named after Dame Jane Francis, who is the first female director of the British Antarctic Survey, the national polar research institute of the UK. Her collection of fossils on Seymour Island helped conclude in a 2021 paper that Antarctica’s abundant plant fossils indicate the continent once had a much warmer climate than it currently does.
Peden Cliffs
Peden Cliffs near Antarctica’s Marie Byrd Land are proof of the labor of Irene Peden. She was the first American female scientist to both live and work in the Antarctic, where she used radio waves to study ice sheets. Peden and her team determined how very low frequency radio waves spread over long polar distances by measuring pathways in the ice. They also used varying radio wave frequencies to measure the thickness of Antarctica’s ice sheets.

6 . Wildfire, or wildland fire, is the uncontrolled fire occurring in a forest, grassland or bushlands.
Fire danger in a wildland setting varies with weather conditions: drought, heat, and wind. Once a fire is burning, drought, heat, and wind all increase its intensity. Topography(地形) also affects wildfire, which spreads quickly uphill and slowly downhill. Dried grass, leaves, and light branches are considered flash fuels, and fire spreads quickly in them, often generating enough heat to burn heavier fuels such as tree stumps(树桩), heavy branches, and the organic matter of the forest floor. Such fuels, ordinarily slow to burn, are difficult to extinguish. Green fuels—growing vegetation-are not considered to catch fire easily, but an intense fire can dry out leaves and needles quickly enough to allow ready burning. Green fuels sometimes carry a special danger. Evergreens, such as pine and spruce(云杉), contain oils that easily burst into flames when heated sufficiently by the searing drafts(灼热的气流) of a forest fire.
Firefighting forces are specially trained to deal with wildfires. Aircraft were first used in fighting wildland fires in 1919. Now airplanes and helicopters are primarily used for dumping water, for observation, and occasionally for assisting in communication and transporting personnel, supplies, and equipment
Tools for fighting wildfires range from the standard equipment of urban fire departments to portable pumps, tank trucks, and earth-moving equipment. It can also change the fire’s direction as well as slowing its progress. They are maintained by public and private owners of forestlands. Such a force may attack a fire directly by spraying water, beating out flames, and removing vegetation at the edge of the fire to contain it behind a fire line. When the very edge is too hot to approach, a fire line is built at a safe distance, sometimes using strip (长条地带) burning to get rid of the fuel in the path of the uncontrolled fire.

10 . Lakes that are called seas
People are always full of imagination to the deep and mysterious sea. However, the waters known as the sea are not always the endless seas we remember, but may also be beautiful or magnificent lakes.
Aral Sea
The Aral Sea is an inland lake that lies to the north of Uzbekistan and to the south of Kazakhstan. Aral occupied a vast area of about 68, 000 square km for a long period of time, but its area has been constantly reducing over the past two centuries and today it’s believed to be less than 10% of its original size.
Dead Sea
The Dead Sea is located between Israel and Jordan in the Jordan Rift Valley. It is actually a salt lake and one of the world’s most salty water bodies. The elevation (海拔) of the Dead Sea’s shores is the lowest and it also enjoys the little of being the world's deepest hypersaline lake. The high salinity (含盐量), of the Dead Sea means it does not support life, hence the name.
Sea of Galilee
The Sea of Galilee is a freshwater lake with “sea” in its name. It is the second-lowest lake in the world after the Dead Sea with the surface elevation ranging from 705 feet to 686 feet below sea level. The Jordan River is the primary source of water for the Sea of Galilee. Underground springs also feed water to the lake.
Erhai Lake
Erhai in Yunnan Province, China, at 1, 972 meters above sea level, covering an area of 250 square kilometers, is one of the seven biggest freshwater lakes in China. It means “sea shaped like an ear” in Chinese. Erhai is reputed as “Pear of Plateau”.
