Most crystalline rocks are much more solid; a common exception is basalt, a form of solidified volcanic lava, which is sometimes full of tiny bubbles that make it very porous.
大部分结晶岩石都非常坚硬，但也有例外，最常见的就是玄武岩，它是一种火山岩浆凝固后的形态，内部充满了微小的气泡，因此也具有多孔渗水的特点。
"We now pretty much understand the solid-state physics of these rocks," Minoru added.
“我们对于岩石的固态物理性质了解的相当多了”明纳路补充说。
The process by which material weathered from rocks is transported by wind, water, ice, or abrasive solid particles, or by mass-wasting, as in rock falls and landslides.
被风化的岩石物质被风、水、冰所搬运、或被磨蚀的固体颗粒或被岩块坡移所搬运的过程，如像在岩崩及滑坡中那样。
Analysis of the lunar samples and impact craters has shown that the Moon's surface was solid 4.3 billion years ago, yet the oldest impact rocks among the samples are 3.9 billion years old.
对月亮石样本和影响的火山口的分析表明月亮表面在43亿年前凝固，然而，样本里面最古老的影响岩石却只有39亿年。
