mantle

• The mantle's motions, analogous to those in a pot of boiling water, cool the mantle by carrying hot material to the surface and returning cooler material to the depths.(地幔的运动类似于一壶沸水的运动，它把热的物质带到表面，再把较冷的物质带到深处，从而使地幔冷却。)
• Since the early twentieth century, geophysicists have understood that the mantle churns and roils like a thick soup.(自二十世纪初以来，地球物理学家已经了解到地幔像浓汤一样搅动和翻滚。)
• 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。)
• The plumes apparently originate at great depths, perhaps as deep as the boundary between the core and the mantle, and many have been active for a very long time.(这些地幔柱显然起源于很深的地方，可能深至地核和地幔之间的边界，而且许多都已经活跃了很长时间。)
• The explanation may be in Earth's mantle, the layer of rock underlying the tectonic plates and extending down over 1,800 miles to the outer edge of Earth's iron core.(解释可能是在地球的地幔中，这是在构造板块下面的岩石层，向下延伸超过1800英里到地球铁芯的外边缘。)
• All are slowly moving because the plates float on a denser sem-iliquid mantle, the layer between the crust and Earth's core.(所有板块都在缓慢移动，因为它们漂浮在密度更大的半流体地幔上，也就是地壳和地核之间的那一层。)
• Much more than the crust, the mantle contains information about a planet's or moon's total composition.(地幔包含的远远不仅是地壳，还有关于行星或卫星的总体构成的信息。)
• By compiling a map of seismic velocities from thousands of earthquakes across the globe, they can also begin to map temperatures and densities throughout the mantle.(通过编制全球数千次地震的地震速度图，他们还可以开始绘制地幔的温度和密度图。)
• The descending rock is substantially cooler than the surrounding mantle and hence is less ductile and much more liable to fracture.(下降的岩石比周围的地幔的温度低很多，因此延展性较小，更容易断裂。)
• Not everyone agrees, but some experts are convinced that whatever created the SPA Basin did penetrate the Moon's mantle.(并不是每个人都同意这个观点，但一些专家相信，无论塑造SPA盆地的是什么，它确实穿透了月球的地幔。)
