The Water Cycle-

Each tidal cycle carries plant material into the offshore water to be used by the subtidal organisms.

每个潮汐周期都会将植物带到近海海水中，从而被潮水下的生物所利用。

You know, I am still not too clear about the hydrologic cycle, the transfer of water back and forth between the earth and the atmosphere.

你知道，我仍然不是很清楚水文循环，也就是水在地球和大气之间的来回转移。

"Many scientists and models have suggested that if the water cycle is intensifying because of climate change, then we should be seeing increasing river flow."

许多科学家根据模型模拟得出，如果水循环因气候变化加剧的话，河流的水量将会增加。
