" As it rose from the sea, layers of liquid magma filled a network of chambers beneath it."

“当它从海上喷发升起时，一层层的液态岩浆填满了它下面网状的岩浆洞室。”

The idea is that water has always been on Earth. Trapped beneath the crust, it's locked in liquid magma.

这一理论是，水一直存在于地球上，被困在地壳之下，锁在液态岩浆之中。

These are bodies of igneous rock, often ore-bearing, that have risen as liquid magma from Earth's interior but solidified before they reached the surface.

这些是火成岩体，通常含矿，从地球内部以液态岩浆的形式上升，但在到达地表之前就凝固了。

Liquid magma is less dense than solid rock, so it rises to the surface in furious bubbles that accumulate in sponge-like reservoirs right under the crust.

因为岩浆的密度比岩石小，它们像剧烈的泡泡般浮到表面，并在地壳下囤积成一个海绵状的岩浆库。

That cool magmaseal allows pressure to build upinside the liquid magma, much like your thumb over the top of a shaken soda bottle will seal inthe pressure.

就像把你的拇指放在被摇过的苏打水瓶口上，使其密封，增加内部压力。
