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 they could erupt again in the future). Geologists study volcanic eruptions and related activities and work to classify each type of volcanic land feature. What they learn gives them more insight into the interior workings of our planet and other worlds where volcanic activity takes place.
