There are over 500 known active volcanoes in the world and thousands of extinct volcanoes. Volcanoes are found on every continent except Australia. There are about 80 active volcanoes under the oceans. Volcanoes are both terrifying and fascinating. In order to understand why volcanic eruptions happen, it is necessary to know some things about how the earth is made.
The part of the earth we live on is an 18-mile-thick layer of solid rock called the crust. Beneath the crust, in a layer called the mantle(地幔) ,it is hot enough to melt some of the rock,creating magma(岩浆).
When the magma finds cracks in the earth's crust, it rises up. Gas bubbles(气泡) inside the magma grow bigger and try to escape as the molten rock gets closer to the earth's surface. When the gas bubbles can't be held back any longer, the volcano erupts. Imagine shaking a soda bottle until the gas inside blows the cap off, and you can understand something of how a volcano erupts. If the magma is runny,and the gas can escape easily, the eruption is gentle. But if the magma is thick,the gas has to build up more pressure to escape. Then the eruption is explosive.
When a volcano erupts,the molten rock that flows from it is called lava. The lava may run for some distance,or it may pile up near the volcano, making the mountain larger.
During an explosive eruption, pieces of rock are thrown from the volcano. Scientists call these pyroclasts (火山碎屑). The smallest pyroclasts are called ash. Ash is often thrown into the atmosphere by the force of the eruption. Larger rocks, about walnut(胡桃) size, are called lapilli, Italian for “little stones”. The largest pyroclasts are called blocks if they are solid,or bombs if they are molten.
Volcanoes have been a major force in the formation of our planet for thousands and thousands of years. Today geologists continually observe active volcanoes for signs of eruption. Using modern instruments, they are usually able to issue a warning before a volcano erupts.
1.The author explains how the volcano erupts by ________.
A.making a comparison B.telling a story
C.using figures D.asking questions
2.The underlined word “it” in Paragraph 3 refers to the “________”.
A.crack B.crust
C.mantle D.magma
3.Whether the eruption is explosive depends on ________.
A.the temperature of the crust
B.whether the magma is thick
C.whether the magma is near the mantle
D.the number of gas bubbles inside the magma
4.We learn from Paragraph 5 that ________.
A.ash is smaller than pyroclasts
B.bombs are about walnut size
C.blocks are larger than lapilli
D.lapilli exist in the atmosphere

Check out our tsunami facts and learn some interesting information related to these great walls of water that can cause so much destruction. Find out what causes tsunamis and read about some recent examples of tsunamis that have occurred around the globe.
The Japanese word for tsunami means harbor wave.
Tsunamis are sometimes referred to as tidal (受潮汐影响的) waves but this term has fallen out of favour because tsunamis are not related to tides.
Tsunamis are huge waves of water that are usually caused by earthquakes or volcanic eruptions.
As a tsunami approaches the shore(海岸), water may move back from the coast. If it is shallow(浅的) enough the water may be pulled back hundreds of metres. If you are in the area, you can know that a tsunami is on the way when you see this phenomenon.
Regions in tsunami danger zones often have warning systems in place to give people as much time as possible to move to a safe place.
When tsunamis hit shallow water (often near the coast) ,they slow down but increase in height.
An earthquake in the Indian Ocean off Indonesia in December 2004 caused a tsunami that killed over 200,000 people in 14 countries.
In March 2011, the Tohoku earthquake off the eastern coast of Japan caused a tsunami that was a major factor in the death of over 15,000 people.
The tsunami waves created by the Tohoku earthquake reached heights of over 40 metres in some areas, wiping out coastal towns and causing a number of nuclear accidents.
5.How many causes of tsunamis are mentioned in the text
A.One. B.Two.
C.Three. D.Four.
6.In the Tohoku earthquake over 15,000 people died mainly because of ________.
A.the earthquake itself
B.the lack of warning systems
C.the tsunami caused by the earthquake
D.the nuclear accidents caused by the tsunami
7.What do we learn from the text
A.The Japanese invented the term “tidal waves”.
B.The term “tidal waves” is used more often than tsunami.
C.When tsunamis slow down, their waves can reach 40 metres.
D.When hitting shallow water, tsunamis will rise higher.
