Find interesting facts about volcanoes and geysers.

Our planet is covered with many volcanoes. About 80% of the earth’s territory was formed by volcanoes. During an eruption, the temperature in the pyroclastic flow can reach, and even sometimes exceed, 500 degrees Celsius. This stream consists of volcanic gases, rocks, and ash. Geysers form in the vicinity of volcanoes. These are seething springs, which from time to time are thrown into the top of the columns of water. These thermal springs are rich in sodium chloride or iodine-bromide water. And Yellowstone Park has the largest number of these springs.
