1·Earthquakes leave scars in the Earth's crust.
地震会在地壳上留下痕迹。
—— 《柯林斯英汉双解大词典》
2·An earthquake is a vibration that travels through the earth's crust.
地震是一种穿过地壳的震动。
3·Earth's crust contains very little of this element, but most asteroids contain a lot more.
地壳中含有的这种元素很少，但大多数小行星上的要多得多。
4·As we've discussed, Earth's crust is made up of large plates that rest on a mantle of molten rock.
正如我们讨论过的，地壳由位于熔融岩石的地幔上的大型板块构成。
5·Underneath the Earth's crust, there are a number of shifting slabs or plates that are slowly moving.
在地壳下面，有许多移动的板块在缓慢移动。
6·The Earth's crust is thought to be divided into huge, movable segments, called plates, which float on a soft plastic layer of rock.
人们认为地壳分成了巨大的、可移动的部分，称为板块，这些板块漂浮在柔软可塑的岩石层上。
7·The first prediction model looks along earthquake faults, those cracks in the Earth's crust, to find what are known as seismic gaps.
第一个预测模型沿着地震断层，即地壳中的裂缝，寻找所谓的地震缝隙。
8·Other mountains may be raised by earthquakes, which fracture the Earth's crust and can displace enough rock to produce block mountains.
另一些山脉可能是由地震引起的，地震使地壳断裂，并移动足够的岩石，从而形成块状山脉。
9·Plate movements are the surface expressions of motions in the mantle—the thick shell of rock that lies between Earth's crust and its metallic core.
板块运动是地幔运动的表面现象。地幔是位于地壳和金属内核之间的一层厚厚的岩石壳。
10·The formation of Earth's crust protected the inner layers of Earth from the high-energy particles in space, reducing the temperatures of the mantle and the core.
地壳的形成保护了地球的内层不受太空中高能粒子的影响，降低了地幔和地核的温度。
