If the magma breaks through to the surface, the result is a volcano. 如果岩浆冲出地面火山就爆发了。
The decompression melting fluid system of asthenosphere provides the driving force for magma emplacement and metallogenic material. 软流圈减压熔融流体系统提供了岩浆侵位动力和成矿物质来源。
Deep beneath the Earth's crust there are pockets of partially liquid rock called magma. 在地壳的深处有很多异体囊,囊中有半液态的岩叫作岩浆。
People will understand what that means from Magma over a period of time. 人们会理解这意味着什么的岩浆在一段时间内。
The lunar crust then formed from low-density minerals that floated to the surface of this magma ocean. 月球地壳便是由浮在岩浆海上的低密度矿物所形成。
The magma within the earth may be heavily charged with gases and steam. 地球内的岩浆可能含有大量的气体和蒸汽。
In many places surface rocks have been melted, baked by the heat of magma beneath. 地表岩石在许多地方被地下岩浆热量所熔化、所烘烤。
Granitic tectono-magmatic assemblages mainly reflect the genetic connections between the magma types of granites and tectonic environments. 花岗岩的构造岩浆组合主要反映花岗岩的岩浆类型与大地构造环境之间的成因联系。
Earthquakes commonly accompany volcanic activity on movement of magma deep in the earth. 地震通常都伴随着火山活动或地球深处的岩浆运动。
Magma is molten rock that flows within the earth. 岩浆是在地球内部流动的熔化的岩石。
The magma is probably generated by rifting. 岩浆的形成可能与裂谷作用有关。
We call this rock material magma. 我们称这种岩石材料为岩浆。
I have heard that the magma is resulted from partial melting of rocks in the depth of the earth. 我听说岩浆是由于地球深处的岩石局部重熔而形成的。
When magma reaches the Earth's surface, we call it lava, or molten rock that flows ground. 当岩浆到达地表,我们称之为熔岩,或者叫在地表流动的熔岩。
The molten rock within was released in a jet of gas and fragmented magma. 内部的熔岩随着喷射的气体和碎裂的岩浆喷涌出来。
