What influence does volcano have on human beings? Please give an example.

1. Volcanic ash is very fertile and suitable for crop growth.

Volcanic eruption will bring a lot of minerals.

Change the terrain

The first is that it can create some land resources for mankind. As I said just now, land resources, like Hawaii Island, were all erupted by volcanoes, and now they are land and American territory. Moreover, volcanoes erupt almost every year on the island of Great Hawaii. After the magma flowed to the seaside, it solidified into land and expanded its territory. If the volcano erupts strongly, it can expand several square kilometers or even more a year. These islands were basically formed by volcanic eruptions. In addition to land resources, it is mineral resources, and there are quite a few mineral resources formed by volcanism, including non-metallic resources and metal resources. That nonmetallic resource is volcanic eruption, almost all kinds of volcanic rocks can be used, and some basalts can be developed as cast stones, such as pumice, volcanic ash and volcanic slag produced in Changbai Mountain, which can be sold in woven bags. In fact, the price is more expensive than white flour. It is a good filling material for repairing advanced airports and gymnasiums. If filled with this kind of volcanic slag, the quality will be higher, and the high-grade cement is also filled with volcanic slag, so the volcano. There are also a lot of minerals related to volcanic eruptions. If you are more interested, you will find precious stones, some of which are volcanic eruptions. Many mineral resources, including some gold mines and some copper mines, are related to volcanism, so volcanoes can create many mineral resources for us.

Second, volcanoes can create many natural landscapes. I can say without exaggeration that most famous scenic spots in the world are volcanic areas, such as Yellowstone National Park in the United States, Hawaii, Mount Fuji in Japan, Changbai Mountain and Wudalianchi in China. At present, there are 4 1 geoparks in China, and there are at least 7 related to volcanoes. Therefore, almost all areas with volcanoes have beautiful scenery. When you go to Japan, you can visit those volcanic areas, and there are endless tourists. This is the Yalu River Grand Canyon in Changbai Mountain, which is formed by volcanic slag and volcanic ash. This is such a spectacular sight. There is a main peak in Changbai Mountain, Jiangjun Peak, which belongs to North Korea and is 2755 meters high. Only model workers and some advanced elements in North Korea can climb the General Peak, which is an honor. Other natural landscapes, such as Aershan mentioned by the media recently, were visited last autumn. This is the autumn scenery, and the crater lake here is very quiet and beautiful. This is Tengchong. Do you think the scenery is beautiful? This is the volcanic area of Tengchong, Yunnan, with volcanoes behind it and rice fields in front.
