What are the factors leading to the collapse of Darwin Arch in Galapagos Islands?

Darwin Arch, a famous perforated landscape in Galapagos Islands, has collapsed due to natural erosion. The prototype of Darwin Arch is British biologist Charles? Named after Darwin, located at the northernmost tip of the Galapagos Islands, it is an arched rock layer standing on the seabed reef. The building is famous for its prominent square columns and circular tunnel-like entrance. It used to be a favorite photography place and sightseeing destination for tourists. The rock structure is 43 meters high, 70 meters long and 23 meters wide, less than one kilometer away from Darwin Island, and it is also one of the famous local tourist attractions. However, tourists are not allowed to set foot on the reef where Darwin Arch is located. Officials believe that the collapse of the arch was caused by natural erosion.

So what caused it? Darwin arch? What are the factors of collapse?

First, natural factors.

Galapagos islands? Darwin arch? It was due to natural erosion that the top collapsed. Natural erosion is also called normal erosion or geological erosion. Refers to the land surface with a certain slope, and its material movement is completely in a natural state without human interference. It is a manifestation of the interaction and mutual restriction between natural forces such as wind, gravity, rainfall, running water and glaciers and anti-erosion factors such as vegetation, surface components and landforms. The existence of natural erosion has brought different degrees of natural harm to human society. Natural erosion in semi-arid areas of China Loess Plateau, such as northern Shaanxi, makes the terrain broken and the land barren. On the other hand, the role of natural erosion shows the magical side of nature to human beings, allowing them to enjoy different scenery, but the harm caused by long-term natural erosion to the ecological environment and human survival can not be ignored. ?

Second, human factors.

Although natural rock arches are easy to collapse due to natural erosion, with the increase of tourists, people begin to worry that species living in this remote area may be destroyed. However, the threat to the Galapagos Islands is not just a problem of more and more tourists. Scientists also warned that this remote destination is also vulnerable to climate change, especially if the El Ni? o phenomenon becomes more common. Changes in rainfall, seawater temperature and other factors may have a major impact on various ecosystems on the island, and then face the danger of collapse.
