There could be an ocean’s worth of water more than 300 miles under the Earth’s surface that equals the known water content across the entire planet. Findings published in the latest issue of the journal, Nature show that water was found in a sample of ringwoodite, a stone formed under...

Secondly, it affects the ocean by altering the density of the ocean surface directly by changing its temperature and its salinity (咸度).The rotation of the earth also tends to affect the currents through the Coriolis force. This force makes water move to the right in the northern hemisphere ...
the sun and the rotation of the earth.The sun affects the ocean by heating the atmosphere, creating winds and moving the sea surface through friction.This tends to drag the water surface along as the wind blows over it.Secondly, it affects the ocean by altering the density of the ocean su...
Their low-frequency calls generate more than 185 decibels (分贝) underwater, on par with a large ship. Part of the energy of this powerful song transmits into the ground as a seismic wave. The wave travels through the oceanic crust where it reflects and refracts off layers in the crustal...
At one place, the Mariana Trench, the ocean floor is almost seven miles below the surface. You could put the highest mountain on Earth in the Mariana Trench-and it would be completely under water! Most of the ocean bottom or floor,...
根据第一段中“Ninety-seven percent of Earth's water is ocean. No blue, no green. If you think the ocean isn't important, imagine Earth without it.(地球上97%的水是海洋。没有海洋,就没有绿色。如果你认为海洋不重要,想象一下没有海洋的地球)”可推知,作者在第一段说“No blue, No green.”...
根据第二段中的“Part of the reason for the lack of observation is the challenge of powering an underwater camera.(缺乏观察的部分原因是水下摄像机的供电困难。)”可知,无法有效地为水下摄像机提供动力限制了研究者的海底探索,结合画线短语前的“Recently, researchers at the Massachusetts Institute of ...
out early, so that the bathyscaphe would come to the surface in daylight, and so be easily found by the mother ship which would be waiting for it. The divers began preparations at dawn and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water. ...
Evidence for subsea permafrost in subarctic Canada linked to submarine groundwater discharge Observations from the Labrador Coast indicate the presence of subsea permafrost landforms outside of the Arctic, suggesting a potential underestimation of subsea permafrost in the world’s oceans. ...
