These ideas are found to be wholly unconvincing once we take a closer look. We find that there are many geological processes that indicate the continents are not as old as evolutionists say. One such problem for the old-age idea is erosion. The continents cannot be billions of years old because they would have eroded away long ago. There should be nothing left.
Bed Load
Water can do its eroding work once it falls as rain. It collects into regions called drainage basins—areas easily identified on a topographic map. By sampling the mouth of the river, we can measure the volume of water discharged from the basin and the amount of sediment it carries. It is difficult to be exact because some sediment is rolled or pushed along the bottom of the river. ‘Bed load’, as it is called, is not easily observed. Sometimes an arbitrary allowance is included to account for it.
Catastrophic Events
Another problem is how to handle rare catastrophic events. Although these can transport huge quantities of sediment in a very short time, they are almost impossible to measure.On the scale of one human life-span, these rates of erosion are low. But for those who say the continents are billions of years old, the rates are staggering. A height of 150 kilometres (93 miles) of continent would have eroded in 2.5 billion years. It defies common sense. If erosion had been going on for billions of years, no continents would remain on Earth.
This problem has been highlighted by a number of geologists who calculated that North America should have been levelled in 10 million years if erosion has continued at the average rate. This is a ridiculously short time compared with the supposed 2.5-billion-year age for the continents.
It has also been suggested that the climate in the past was much drier (because less water would mean less erosion). However this idea goes against the evidence. The climate was actually wetter, as deduced from the abundance of lush vegetation in the fossil record.
The Yellow River in China could flatten a plateau as high as Everest in 10 million years. The mountain ranges, such as the Caledonides of western Europe and the Appalachians of eastern North America are even harder to explain because they are not as high as Everest, yet are supposed to be several hundred million years old. If erosion has been going on for this long, these mountains should not exist." CMI
