海平面并非指全球所有地方的水面高度，而是特指有海洋存在的地方的平均水面高度。在远离海洋的地区，海平面的定义变得复杂，因为无法直接通过观测来确定。地球形状的影响：地球是一个旋转的椭球体，赤道处因离心效应而略鼓，两极被压扁。这导致不同地区的海平面高度存在差异，例如赤道上的海平面可能比北极高...
That means if you thought earth were a sphere(n.范围;球体;vt.包围;放入球内;使...成球形)and defined(vt.定义;使明确;规定)sea level by standing on the sea ice at the north pole, then the surface of the ocean at the equator would be 21km above sea level. 这意味着如果你认为地球是球...

解析 C。原因:As the sea level rises, habitats for many species are being lost. This not only reduces the available living space for these organisms but also disrupts their life cycles.(随着海平面上升,许多物种的栖息地正在消失。这不仅减少了这些生物的可用生存空间,还扰乱了它们的生命周期。)...
由题干中的the rising sea level定位到第一段第一句...sea levels could rise if Antarctica’s massive western ice sheets fully disintegrated as a result of global warming.可知,由于全球气候变暖南极洲西部的巨大冰原完全解体,从而导致海平面上升。[B]“全球气候变暖”与原文内容一致,故正确。[A]“冰原解体...
However, just like the surface of the land on our planet Earth, the surface of the oceans is not level either. The sea level on the West Coast of North America is usually about 8 inches higher than the sea level on the East Coast of North America. The surface of the ocean and its ...
