海平面是指海洋的平均高度，但这一概念的确定涉及多个复杂因素。以下是关于海平面的几个关键点：定义与局限性：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...
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...

What is the absolute pressure at sea level?Absolute pressureAbsolute pressure is a measure of the pressure exerted against a vacuum. This is different from gauge pressure, as gauge pressure is measured as the difference against atmospheric pressure....
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。)...
[1] As sea level rises, many coastal marshes worldwide are predicted to submerge. What is the maximum rate of sea level rise that a coastal marsh can survive? Many previous studies of this question have assumed that the coastal wetland landscape is static, but, in fact, many coastal ...
While it’s impossible to know exactly how the next decade will unfold, scientists and climate experts have made projections, factoring in the current state of affairs. 4. This future we’re about to describe is bleak, but remember there’s still time to ensure it doesn’t become our reali...

Voyages typically last about 100 days and participants can visit at least 10 countries. The spring 2024 trip itin...
When it is stated that "sea level is rising," this usually refers to "mean sea level," which is the average sea level around the earth based on numerous measurements over a long period of time. The elevation of mountain peaks are measured as the height of the peak of the mountain above...
