89 - How do volcanoes create new land?

When a volcano erupts, it shoots out molten lava and ash into the air. When the lava cools down, it solidifies and forms a new layer of rock on top of the old land. Over time, if the volcano erupts many times, these layers of rock can build up and rise above the surrounding water or land, creating a new island or adding to an existing one.

For example, the Hawaiian Islands were formed from volcanic eruptions. The lava flowed from the volcanoes, cooled down, and solidified, creating new land that eventually rose above the water. That's why volcanoes can create new land, like islands or mountains.
