地質學五句,請幫忙英翻中。

most of the sand on beaches is supplied not by erosion of wave-cut cliffs but by alluvium carried to the sea at times of flood.

of the sand and pebbles that form the natural beaches there, 90 percent used to be supplied by rivers as they entered the sea.

all this construction interfered with the steady state that had existed among the supply of sediment to the coast, longshore currents and beach drift, and deposition of sediment on beaches.

Unusual depositional conditions are common when an ocean basin initially opens, and in its last stages of closure.

photosynthesizing marine organisms exchange dissolved CO2 for dissolved O2 in surface water, and a wide variety of organisms draw bicarbonate anions out of seawater to form calcium carbonate shells.

    most of the sand on beaches is supplied not by erosion of wave-cut cliffs but by alluvium carried to the sea at times of flood.

    大部份海灘上的砂不是由海浪切削峭壁的侵蝕而來,而是由洪水氾濫時被帶到海邊的沖積層產生。

    of the sand and pebbles that form the natural beaches there, 90 percent used to be supplied by rivers as they entered the sea.

    在那裡組成天然海岸的砂和小石頭,百分之九十都是當河流入海時候帶過來的。

    all this construction interfered with the steady state that had existed among the supply of sediment to the coast, longshore currents and beach drift, and deposition of sediment on beaches.

    所有這樣的結構和已經存在的穩定狀態是衝突的;這些穩定狀態包括供給海岸的沈積,沿岸的海流和海灘的漂移,還有沈積物在海灘的沈澱。

    Unusual depositional conditions are common when an ocean basin initially opens, and in its last stages of closure.

    通常在海灣初期開口,還有在末期閉口時這種不尋常的沈積情形都是很平常的。

    photosynthesizing marine organisms exchange dissolved CO2 for dissolved O2 in surface water, and a wide variety of organisms draw bicarbonate anions out of seawater to form calcium carbonate shells.

    海洋生物的光合作用在上層水域中將溶解的二氧化碳轉變為溶解的氧氣,而一個廣泛的多重生物組織將海水中的重碳酸鹽陰離子轉變成碳酸鈣外殼。
