Plant life balances ecosystems, protects watersheds, mitigates erosion, moderates climate and provides shelter for many animal species.(植物平衡了生态系统、保护了流域、减缓了侵蚀、缓和了气候，为许多动物物种提供了庇护所。)
Unfortunately, such estimates did not adequately account for past differences in rates of sedimentation or losses to the total section of strata during episodes of erosion.(不幸的是，这种估测没有充分考虑到过去在侵蚀期间沉积速率或地层总剖面损失的差异。)
During the seventeenth and eighteenth centuries, the entire site became covered with a layer of hard grey clay, which minimised further erosion.(在十七世纪和十八世纪，整个遗址被一层坚硬的灰色粘土覆盖，这极大减少了进一步的侵蚀。)
Attack by scavengers and bacteria, chemical decay, and destruction by erosion and other geologic agencies make the odds against preservation very high.(食腐动物和细菌的攻击、化学性腐烂，以及侵蚀和其他地质作用的破坏，导致无法保存的可能性非常大。)
The green ice portion was textured by seawater erosion.(绿色的冰部分被海水侵蚀，并形成纹理。)
In contrast, the roots of grasses and other small plants may help to hold loose soil fragments together, thereby helping to prevent erosion by the wind.(相反，草和其他小植物的根可能有助于把松散的土壤碎片固定在一起，从而助于防止风的侵蚀。)
Because the Moon has no atmosphere, its surface is not subject to erosion, so it retains the marks of its early history.(由于月球没有大气层，它的表面不会受到侵蚀，所以它保留了早期历史的痕迹。)
In all these diverse regions, Agassiz saw signs of glacial erosion and sedimentation.(在这些不同的地区，Agassiz都能发现冰川侵蚀和沉降的痕迹。)
The clay deposits are scattered all over, in ancient volcanic surfaces and heavily cratered highland regions, some of which have apparently been exposed by erosion only recently.(粘土沉积分布在古代的火山表面和坑坑洼洼的高原地区，其中一些显然是最近才由于侵蚀而暴露出来的。)
The simulation takes no account of the effects of coastal erosion.(该模拟没有考虑海岸侵蚀的影响。)
