No very satisfactory account of the mechanism that caused the formation of the ocean basins has yet been given.
对于造成海洋盆地形成的机制，至今还没有给出非常令人满意的解释。
Extreme changes in daily and seasonal climates preceded the retreat of the seas back into the major ocean basins.
在海洋退回到主要的海洋盆地之前，每日天气和季节性气候发生了剧烈的变化。
At the end of the Cretaceous, the geological record shows that these seaways retreated from the continents back into the major ocean basins.
地质记录显示，在白垩纪末期这些航道从大陆撤退，回到主要的海洋盆地。
They therefore permit the reconstruction of the process of seafloor spreading, and consequently of the geography of continents and of ocean basins in the past.
因此，它们可以重现海底扩张的过程，以及大陆和大洋盆地过去的地理位置发展过程。
A key aspect of plate tectonic theory is that on geologic time scales ocean basins are transient features, opening and closing as plates shift.
板块运动理论的一个关键点就是在地质历史的尺度内，海洋盆地的开合是因为板块转换，具有转换特征。
The problem is that scientists are just beginning to understand what will happen to climate at scales smaller than entire continents or ocean basins.
问题在于科学家才刚开始了解次洲或者次洋级的气候变化。
At the end of the Cretaceous, the geological record shows that these seaways retreated from the continents back into the major ocean basins. No one knows why.
在白垩纪后期，地质资料表明这些浅海都从大陆退回到主要的海洋盆地内了，没有人明白为什么。
Earth has more than enough water to completely fill the ocean basins, and the rest of it spreads onto edges of the continents, areas known as the continental shelf.
地球上的水量比充满洋盆所需的水量要多，剩余的部分分布在大陆的边缘，就是我们称为大陆架的地方。
Most deep ocean basins range in depth from about 4 to 6 kilometers, with some narrow trenches near Pacific ocean basin margins dropping to as low as 11 km below sea level.
大多数海盆在深度上从4公里到6公里左右，在太平洋附近海盆边缘有些狭窄海沟可以陡降到海平面以下11公里处。
They are also found in volcanic “back-arc” basins behind ocean trenches, where one tectonic plate is sliding beneath another.
在海沟后侧的弧后盆地的火山中，此处是一个板块俯冲到另一板块的地方，也发现了该类通道，。
The marginal basins along the trough between different massifs or the marginal zone between massif and ocean trough are favorable for oil and gas generation.
地块之间的海槽或地块与海槽过渡的边缘带盆地是油气形成的有利地带。
The hypothese of regional right lateral shear pulling apart is the starting point in revealing the genesis of the basins in the northwest Pacific Ocean margin.
局部区域的右行剪切拉分说是揭示西北太平洋边缘盆地成因的良好开端。
