1·The impact of rainfall upon the surface water and groundwater resources of the desert is greatly influenced by landforms.

降雨对于沙漠地表水和地下水资源的影响很大程度上取决于地形。

2·Also, in surface water, there is a weak acid, carbonic acid, not sulfuric acid, but carbonic acid that helps dissolve the rock.

另外，在地表水中存在一种弱酸，它是碳酸，而不是硫酸，而且是能帮助溶解岩石的碳酸。

3·And, since they were created underground and not from flowing surface water, not all these passageways have an opening to the outside world.

并且，由于它们是在地下形成的，而不是由地表水流形成，所以并不是所有的通道都有通向外部世界的开口。

4·Within about a millimeter of the water, air temperature is close to that of the surface water, and the air is nearly saturated with water vapor.

在离水不到一毫米的地方，空气的温度接近于地表水的温度，空气中的水蒸气几乎饱和了。

5·Conversely, a pond with a stream flowing in one end and out the other, which dries up when the stream dries up, is clearly surface water dominated.

相反，有径流从两端流进流出的池塘，在径流枯竭的时候也会干涸，地表水就明显占据主导地位。

6·Recently, researchers have used data collected by monitoring surface water temperatures to improve the ability of a reef to recover from bleaching.

最近，研究人员通过监测表面水温获得数据，并用此数据来提升珊瑚礁从漂白状态中恢复的能力。

7·Because the surface of the water table is not flat but instead rises and falls with topography, groundwater is affected by gravity in the same fashion as surface water.

由于地下水位不是平面的，而是随着地形起伏的，所以地下水和地表水一样受到重力的影响。

8·The latter two sources are limited to those few areas where surface water seeps down through underground faults or fractures to reach deep rocks heated by the recent activity of molten rock material.

后两种来源局限于少数区域，在这些区域，地表水通过地下断层或断裂往下渗透，从而接触到被近期的熔岩活动加热的深层岩石。

9·Sunlight and surface water play no role. It's amazing!

阳光和地表水在这里没有扮演任何角色，这太让人惊奇了。

10·So there must be surface water too — even if it is loaded with arsenic.

所以必须表面也有水——即使它里面装满了砷。

地表水

1·Within about a millimeter of the water, air temperature is close to that of the surface water, and the air is nearly saturated with water vapor.

在离水不到一毫米的地方，空气的温度接近于地表水的温度，空气中的水蒸气几乎饱和了。

2·The impact of rainfall upon the surface water and groundwater resources of the desert is greatly influenced by landforms.

降雨对于沙漠地表水和地下水资源的影响很大程度上取决于地形。

3·Also, in surface water, there is a weak acid, carbonic acid, not sulfuric acid, but carbonic acid that helps dissolve the rock.

另外，在地表水中存在一种弱酸，它是碳酸，而不是硫酸，而且是能帮助溶解岩石的碳酸。

4·She makes her home in urban Ghana where, as she describes, Any surface water is an open sewage stream.

正如她所说，她的家在加纳市区，“在那里，任何地表水都是开源污水流。”

5·In some places it is indeed replenished quite quickly if rain or surface water is available and the geological and soil conditions are favourable.

确实，在一些雨水和地表水丰富并且地质和土壤环境理想的地方，地下含水层可以很快就得到补充。
