Chapter 1
Mount Saint Helens
In 1980, rumbles shook the ground around Mount Saint Helens, a mountain in the state of Washington. Scientists watched the mountaintop grow larger and larger. They saw cracks forming, and they knew something big was about to happen. All of a sudden there was a big BOOM! The mountaintop exploded with a roar. The huge blast destroyed millions of trees. It flattened them like a bunch of sticks. Heat from the blast melted the snow on top of the mountain. The melted snow mixed with dust. It made a thick mud that raced down the mountainside. The mud buried houses, cars, roads and bridges. Early Warning
Months before the blast, scientists saw clues that Mount Saint Helens was about to burst. The police warned people who lived near the mountain to leave their homes. They also warned workers, reporters, and visitors to leave the area. Hundreds of lives were saved because people left before the huge blast.
Chapter 2
How a Volcano Forms
Mount Saint Helens is a volcano.
A volcano is an opening in the Earth through which lava, ash, and gases come out. Lava is hot, melted rock that comes from deep inside the Earth. Ash is small bits of lava and rock. Gas gets trapped in melted rock inside the Earth. The gas escapes when a volcano explodes. Then lava and rocks shoot out. This is a little like shaking a bottle of soda and then opening it.
The gas in the soda causes the liquid to bubble up over the top of the bottle. Some volcanoes are active. They burst, or erupt, often. Some volcanoes are dormant. This means they have not erupted for a very long time. Dormant volcanoes seem to be sleeping. Before 1980, Mount Saint Helens was dormant for more than 100 years. Not all volcanoes look like Mount Saint Helens when they erupt. When this big volcano erupts, red-hot lava f lows from openings in the mountain.

第一章
圣海伦斯火山
1980年,华盛顿州圣海伦斯山(Mount Saint Helens)周围的地面轰隆作响。科学家们看着山顶越来越大。他们看到了裂缝的形成,他们知道一些重大的事情即将发生。突然,一声巨响!山顶轰隆一声爆炸了。巨大的爆炸摧毁了数百万棵树。它像一捆棍子一样把它们压扁了。爆炸产生的热量融化了山顶上的雪。融化的雪夹杂着灰尘。它形成了一层厚厚的泥浆,顺着山坡往下流。泥土掩埋了房屋、汽车、道路和桥梁。预警
爆炸前几个月,科学家们发现了圣海伦斯山即将爆炸的线索。警察警告住在这座山附近的人离开他们的家。他们还警告工人、记者和游客离开该地区。由于人们在大爆炸前离开,数百人的生命得以挽救。
第二章
火山是如何形成的
圣海伦斯山是一座火山。
火山是地球上的一个开口,熔岩、火山灰和气体通过它流出。熔岩是来自地球深处的热熔岩。火山灰是少量的熔岩和岩石。气体被困在地球内部熔化的岩石中。火山爆发时气体逸出。然后熔岩和岩石喷发出来。这有点像摇动一瓶苏打水然后打开它。
苏打水中的气体使液体在瓶子顶部起泡。有些火山是活的。它们经常爆发。有些火山处于休眠状态。这意味着它们已经很久没有爆发了。休眠的火山似乎正在休眠。1980年以前,圣海伦斯山休眠了100多年。并非所有火山喷发时都像圣海伦斯山。当这座大火山喷发时,红色炽热的熔岩从山上的开口流出。
