It is gradually slowing down and factors such as disruptions in the earth's core, extreme weather, volcanic eruptions and earthquakes can all influence the precise length of the astronomical day.
地球的自转正在逐渐的慢下来，而像地核分裂、极端天气、火山爆发、地震发生等事件都会影响天文日的确切长度。
Because of its proximity to Earth's core, the rock at the base of the mantle is much hotter than rock in the upper mantle.
由于靠近地核，地幔底部的岩石比上地幔岩石的温度高得多。
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 semi-liquid 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液态地幔上，也就是地壳和地核之间的那一层。
Continued bombardments and internal pressures made the growing Earth hotter, causing its interior to melt and the heavier elements to sink and form Earth's core.
持续的轰击和内部压力使成长中的地球越来越热，导致其内部融化，较重的元素下沉形成地核。
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 Earth's magnetic field is generated as the molten iron of the Earth's outer core revolves around its solid inner core; when surges in the molten iron occur, magnetic tempests are created.
