Volcanoes-va

**VINCENT Web Page ** Volcanoes Do you want to know how volcanoes are created? Volcanoes are created by cracks and holes that poke through the earths crust. Deep beneath the rocks the crust is so hot that some rocks melt, that is called magma. Rocks, lava, and a plug are parts of volcanoes. Mountains and islands are often formed when magma reaches the surface and cools into solid rock. Are you wondering how lava comes out of volcanoes? Sometimes magma cools down before getting to the top. It plugs the hole where the magma comes out. Hot gasses from the the magma pressses aganist the plug. Pressure grows and the volcano explodes .Did you know that an eruption can last up to 1 day to 20 years. Here are somethings volcanoes help us with? Volcanoes are important because they make islands and soil. After the lava it brings us new mountains, islands and soil to the land.

Watch out for hot lava and rocks that shoot up. Volcanoes are dangerous beacuse the lava can kill people and the dust can cause breathing promblems and the dust can stay in the air for a long time. That is somethings about Volcanoes. By.Vincent
