A
Volcanoes are a threat all over the world. It can kill lots of people when it erupts(爆发). But some scientists have new ways to tell when they will erupt. Let's learn about what a volcano is and high-tech detectives about volcanoes.
　　What are volcanoes
　　A volcano is a crack(裂缝) in the Earth. The opening is caused by gas and hot liquid rock, called magma(岩浆). The gas and magma rise from deep inside the Earth. A volcano erupts when gas and magma push through the Earth's surface. Magma that flows out of the ground is called lava. Lava can sometimes build up around a volcano and form a cone-shaped mountain. Lava can also pour along the ground, destroying everything in its path.
　　High-tech detectives
　　The good news is that scientists can now help keep people safe. Scientists can get to an active volcano within 48 hours of the first sign of trouble. Researchers also have new ways to know when a volcano may erupt. They use satellites to watch volcanoes. They put sensors at the base of a volcano. Then they tune them to a satellite circling Earth. The sensors feel rumbles(隆隆声) as magma and gases move inside the volcano. The satellites find the location of each sensor. A computer puts the information together to make a picture of inside the mountain.
　　These tools help scientists and researchers study the volcanoes. Then they can predict when a volcano may erupt.

A. 岩石 B. 熔岩 C. 灰烬 D. 火山
