2. What is a Volcano?
A volcano is a mountain that forms when magma reaches the surface of the Earth. When magma breaks through a weak spot in the Earth’s surface, a volcano is formed. When a volcano erupts, gases, ashes and rocks are forced out.

3. Effects of a Volcanic Eruption
When a volcano erupts, a lot of destruction can be done to nearby homes and people. A long time ago, a city called Pompeii, was completely destroyed when a volcano named Mt. Vesuvius erupted.
Volcanoes can be helpful too. The hot rocks that come out of a volcano are rich with minerals. These minerals are great for growing plants.

4. Our Thoughts and Questions
We never knew that volcanoes can be helpful. We wonder if scientists have a way to figure out when a volcano will erupt.
