Coral reefs exposed above the sea surface in turn experience erosion , sedimentation , and soil formation , leading to the establishment of vegetation and complex ecosystems-including in many cases human habitation .
Sedimentation , weathering , uplift -- all the grand geological forces -- also act as strong chemical agents , breaking and making the bonds of materials .
沉降、风化、隆起所有巨大的地质力量也如强大的化学作用那样,打断或合成物质的分子链。
The second part of the project , a study of sedimentation and the ancient climate , will follow up dr wang 's original examination of the area , in 1999 , which was part of an international effort called the ocean drilling programme .
Additional sedimentation occurred until a subduction zone formed off the coast .
直至一个潜没带在距离海岸处形成前,额外的沉积作用一直存在。
These ratios indirectly measure the amount of water locked up in glacial ice sheets at the time of sedimentation .
这些比值可以间接测量沉积过程中锁定在冰川冰层内的水量。
Human waste is channelled into a septic tank and undergoes an initial step of sedimentation and anaerobic digestion .
人体排泄物引排到化粪池后先要经过沉降和厌氧分解的过程。
Repeated aerial surveys over the coming years will also give the researchers insight into how vegetation recovers from fires , how the beetles affect this process , how erosion and sedimentation affect the region 's water resources , and whether fire creates opportunities for new species to invade .
