美国科罗拉多州地质学Essay代写:火山是如何运作的?

每天都有一座火山在太阳系的某个地方爆发。地球上点缀着活跃的火山特征,如巴厘岛非常活跃的阿贡山,冰岛的巴尔巴邦加和墨西哥的科利马。木星的月亮Io是高度火山的,从其表面下喷出含硫的熔岩。土星的卫星土卫二也具有与火山活动有关的间歇泉特征,但它不像地球和岩石上的熔岩那样喷发,而是喷出泥泞的冰晶。当火山喷发时会发生什么?当火山喷出熔岩和其他物质时,火山在建造地貌和重新铺设地球上的景观方面做了大量的工作。在地球上,火山已经存在,因为这个星球是婴儿,它们在创造大陆,深海沉积物,山脉,火山口以及帮助建立我们的大气层方面发挥了作用。并非所有从一开始就流动的火山目前都是活跃的。有些人已经死了,永远不会再活跃。其他人处于休眠状态(这意味着他们将来可能再次爆发)。地质学家研究火山爆发和相关活动,并对每种类型的火山地面特征进行分类。他们学到的东西让他们更深入地了解我们星球的内部运作以及火山活动发生的其他世界。 美国科罗拉多州地质学Essay代写:火山是如何运作的? Every day a volcano erupts somewhere in the solar system. Earth is dotted with active volcanic features such as the very active Mount Agung in Bali, Bárðarbunga in Iceland, and Colima in Mexico. Jupiter's moon Io is highly volcanic, spewing sulfurous lava from beneath its surface. Saturn's moon Enceladus also has geyser features related to volcanism, but instead of erupting with molten rock as on Earth and Io, it spews out slushy ice crystals. What happens when a volcano erupts? Volcanoes do major work in building up landforms and resurfacing landscapes on Earth as they spew out lava and other materials. On Earth, volcanoes have been around since the planet was an infant, and they played a role in creating the continents, deep-sea deposits, mountains, volcanic craters, and helped build up our atmosphere. Not all volcanoes that have flowed since the beginning of time are currently active. Some are long-dead and will never again be active. Others are dormant (meaning...

美国科罗拉多州地质学Essay代写:墨西哥洞穴的巨型水晶柱

这个极其美丽的结晶洞穴拥有一个致命的环境,温度永远不会低于58摄氏度(136华氏度),而湿度则徘徊在99%左右。即使穿着防护服,人类一次只能承受十分钟的危险情况。因此,禁止旅游;只有科学家进入洞穴,矿工作为指导。亚硒酸盐针头需要一个温暖潮湿的环境才能生存,科学家们必须迅速行动才能在洞穴到达时研究洞穴。在严格条件下工作以防止污染的微生物学家钻入柱中,以获取可能存在于晶体内的流体中的生命形式的样品。2017年初,研究人员发现在晶体内发现休眠微生物。至少在1万年前,甚至可能长达5万年前,它们可能已被困在水晶中。生活在山洞中的一些细菌与地球上其他任何已知的生命形式都不匹配。虽然微生物在科学家发现它们时处于休眠状态,但研究人员能够在实验室中重新找到它们,以获得更多关于它们在洞穴中的情况以及它们被困时的情况。这些“虫子”被称为“极端微生物”,因为它们可以存在并在极端恶劣的温度,湿度和化学条件下存活。今天,随着采矿作业的停止,泵送停止了。目前,再浸水已经保存了晶体,但它也向室内引入了与环境无关的新生物体。 美国科罗拉多州地质学Essay代写:墨西哥洞穴的巨型水晶柱 This eerily beautiful crystalline cave houses a deadly environment, where the temperature never drops below 58 degrees Celsius (136 F), and the humidity hovers around 99 percent. Even dressed in protective gear, humans can withstand the dangerous conditions for only about ten minutes at a time. As a result, tourism is forbidden; only scientists have accessed the cave, with miners acting as guides. The selenite needles require a warm, wet environment to survive, and scientists had to move quickly to study the cave while it was accessible. Microbiologists, working under stringent conditions to prevent contamination, bored into the columns to get samples of life forms that might exist in the fluids trapped inside the crystals. In early 2017, researchers reported finding dormant microbes inside the crystals. They had probably been trapped inside the crystals at least 10,000 years ago and possibly as long as 50,000 years ago. Some bacteria living in the cave do not match any other known life...
