Magma occurs deep within the earth and is made up of a mixture ofmoltenmineral materials. Sometimes magma reaches the surface through volcanoes. Then the molten rock is called lava. 岩浆是形成在地球的深部,它是熔融的物质的混合物。当岩浆通过火山口溢出地表时,便可称这种熔融的岩石为熔岩。
Molten rock that comes to the surface of the earth is called:d. cemented
As I said previously themoltenrock material is called magma if it is beneath the surface and called lava if it is on the surface. 比如我前面所说的那样,熔融岩石物质位于地表之下时称之为岩浆,位于地表时称其为熔岩。 属类:工程技术-地质-地质与勘探 ...
Then the molten rock is called lava. 当岩浆通过火山口溢出地表时,便可称这种熔融的岩石为熔岩。 During the night it could only be compared to a Niagara of molten fluid, with its incandescent vapors above and its boiling masses below.
aWhen a volcano erupts,the molten rock that flows from it is called lava.Then lava may run for some distance,or it may pile up near the volcano,making the mountain larger. 当火山喷发,流程从它称熔岩的溶解的岩石。然后熔岩也许为某一距离跑,或者它也许在火山附近堆,使山更大。[translate]...
Shale under pressure becomes slate.One factor that does not cause a change in rock structure is ___. A.heatB.windC.pressureD.solution 3Rocks which have solidified directly from molten materials are called igneous rocks. Igneous rocks are commonly referred to as primary rocks because they are...
Passage 4(原创)Lava is the molten rock when it flows out of a volcano, which can be as hot as 2,000 Fahrenheit.1 . So, what's so dangerous about a volcanic eruption?Sometimes lava doesn't flow out of a volcano, but instead it explodes. When the exploding mixture of hotgas lava ...
aWhen a volcano erupts,the molten rock that flows frow it is called lava.Then lava may run for some distance,or it may pile up near the volcano,making the mountain larger. 一座火山爆发时,淹没它称为的 frow 的熔铸的岩石 lava.Then 熔岩可能争取一些距离,或它可能在火山附近搁浅,使山变得更大...
18、Remember, magma is hotmoltenrock that's underground, and it is called lava when it reaches the surface.(记住,岩浆是地下炽热的熔化了的岩石,当它到达地表时就被称为熔岩。) 19、Zircon starts off asmoltenmagma, the hot lava from volcanoes.(锆石开始是熔融的岩浆,来自火山的热熔岩。) ...
