Volcanoes are found in many parts of the world. Some are far from towns and cities, but people live near others. Many volcanoes look like mountains, and they may stay quiet for hundreds of years.

Far under the ground, rock can become so hot that it turns into liquid. Gas in this hot rock can create pressure. The pressure can push the rock toward the top of the volcano. When hot rock, gas, and ash come out, the volcano erupts. This is called an eruption.

The hot rock that comes out is called lava. It can move quickly down the sides of the volcano. An eruption can also send ash, gas, and pieces of rock high into the air. This can be dangerous for people who live nearby.

Scientists watch volcanoes that may erupt again. When they think an eruption is coming, they warn people nearby. People may need to leave their homes and move far away until it is safe to return.
