帮忙把这四句话翻译成英语

盐物质,即岩浆。它一旦从地壳薄弱的地段冲出地表,就形成了火山。火山爆发能喷出多种物质。

在地球上已知的“死火山”约有2000座;已发现的“活火山”共有523座,其中陆地上有455座,海底火山有68座。火山在地球上分布是不均匀的。
活火山(active volcano)
死火山(extinct volcano)

火山爆发喷出的大量火山灰和暴雨结合形成泥石流能冲毁道路、桥梁,淹没附近的乡村和城市,使得无数人无家可归。

火山作用对我们来说也有好处。火山附近常有温泉或热泉,这就是因为岩浆散发出的热度使地下水变热而形成的

Once magma or lava rushes out of the weakest / thinnest part of the earth's crust, it carries various kinds of substances and forms a volcano .

死火山(extinct volcano)
Already known on the earth are about 2000 extinct volcanoes ,and 52 active volcanoes of which 52 lie on land and 68 lie in the sea.Volcanoes are irregularly located on the earth.

火山爆发喷出的大量火山灰和暴雨结合形成泥石流能冲毁道路、桥梁,淹没附近的乡村和城市,使得无数人无家可归。
The great amount of lava that comes up from below the earth's surface mixes with the heavy rain can destroy roads and bridges,submerge nearby villages and towns and cities and make numerous people homeless.

火山作用对我们来说也有好处。火山附近常有温泉或热泉,这就是因为岩浆散发出的热度使地下水变热而形成的
Volcanism may also bring something good. Near a volcano, often there are hot springs which are formed by underground water that gets hot as the result of the heat of the magma .

Lava is salty materials. As soon as it jump out of the weak parts of the earth, volcanoes are formed. Volcanoes can erupt many materials.

There are about 2000 known extinct volcanoes on earth; and there are 523 known active volcanoes. 455 of them are on land and 68 of them are under the sea. They are distributed unevenly.

The combination of volcano ash and rainstorm can form mudslide which can destroy roads, bridges, flood the nearby countrysides and cities, making many people homeless.

However, volcanoes are also beneficial for us. There are often many hot springs near the volcanoes because the heat generated by lava makes the underground water hot.追问

把第一段改一下,上半句没复制到
地壳之下100至150千米处,有一个“液态区”,区内存在着高温、高压下含气体挥发份的熔融状硅酸盐物质,即岩浆。它一旦从地壳薄弱的地段冲出地表,就形成了火山。火山爆发能喷出多种物质。

追答

There is a "liquid zone" that measures 100 to150 kilometers under the earth crust, where there exists the liquated silicate materials that contain gas in high temperature and pressure, which is called lava. As soon as it jumps out of the weak parts of the earth, volcanoes are formed. Volcanoes can erupt many materials.

Salt material, that magma. Once it is out of the lot from the weak surface crust to form the volcano. Volcanic eruptions can emit a variety of substances.

Known on Earth, "extinct" about 2000; have found the "active volcano" A total of 523, of which there are 455 land, sea volcano 68. Distribution of volcanoes on Earth is not uniform.
Active volcanoes (active volcano)
Extinct (extinct volcano)

Large volcanic eruptions of ash and debris flows can combine to form rain washed away roads, bridges, flooding nearby villages and cities, making many people homeless.

Volcanism is also good for us. Often near hot springs or volcanic hot springs, this is because the heat emitted magma heats groundwater formed
