PaginePaginepagineapp.comA volcano is an opening in Earth's surface. Deep underground, it is so hot that rock melts into a liquid called magma.
When magma rises and flows out of a volcano, it is called lava. Lava can be hotter than 1,000 degrees Celsius. As it cools, it hardens into new rock.
Some volcanoes erupt often, while others have been quiet for thousands of years. Scientists called volcanologists study volcanoes to warn people before eruptions.
Volcanoes also help build land. The islands of Hawaii were formed by volcanoes over millions of years.
