"Lightning is very significant in causing landscape erosion and the formation of lots of fractured bedrock," Knight told LiveScience's OurAmazingPlanet. An article in LiveScience quoted Knight, saying, Not only can today’s weathering processes account for the collapse of arches and other exposed features, but lightning can cause significant weathering in bare rock settings, such as mountaintops. Observed erosional processes do a lot of geologic work that doesn’t require millions or even hundreds of thousands of years. At this observed erosion rate, there wouldn’t be any White Cliffs of Dover in much less than a million years. We’re seeing a lot-too much-catastrophic erosion of these magnificent cliffs over a short time.
Eyewitnesses say they heard a 'loud crack,' before swathes of rock fell into the sea. This recent collapse saw tons of chalk break off near Samphire Hoe Country Park. A huge portion of the White Cliffs broke off and fell into the Channel February third of 2021. In 2001, a huge chunk fell into the English Channel followed by another large section in March 2012. But there has been significant fracturing of the cliffs every decade or so. Evolutionists estimate a paltry 0.39” of erosion per year. Supposedly, the White Cliffs of Dover were formed in the Cretaceous many millions of years ago. “A massive sheet of rock has fallen from the vertical face of the Half Dome in Yosemite National Park, making one of the most popular routes attempted by climbers in North America even more challenging, park officials said.The granite sheet that peeled off measured roughly 100 by 200 feet.” 4 It was first noted by a surveying team in 1805. The Great Stone Face, also called the Old Man of the Mountain in New Hampshire, was composed of five granite cliff ledges, which, when viewed from the north, looked like the profile of a human face. There are other geologic features that have yielded to continuous erosion. In May of 2021, a well-known geological feature called Darwin’s Arch off the coast of the Galapagos Islands succumbed to various forces and has collapsed into the Pacific Ocean. A park ranger noticed it was no longer standing during a hike in February.” 2 “Rainbow Arch, located just above the visitor center in Arches National Park, collapsed sometime this winter. Not only wind carves the rock, but also the cycle of heat and cold causes cracks in the softer sandstone, eroding it away, and leaving the caprock. One can appreciate the erosional processes at work. It’s found in Devils Garden of the Grand Staircase-Escalante Monument in south-central Utah. The Metate Arch composed of sandstone is very thin and is near the end of its life.
Through unrelenting erosion, even the caprock erodes and will ultimately cause collapse of these seemingly timeless features. Over the centuries, arches form due to erosion where softer rock is removed, producing alcoves and leaving harder caprock at the top.
Other arches have also formed as artifacts of the receding phase of the Flood. Natural stone arches are commonly made of sandstone or limestone and are found in coastal cliff areas that can be eroded by wave action.
