Volcanoes are mountains with large holes called craters at the top that produce melted rock during eruptions. They form at boundaries between tectonic plates where one plate is pushed under another, allowing magma and gases to escape through vents in the crust during eruptions. The output from volcanoes can both create new land and impact the weather through emitted particles and gases.

A volcano is a mountain with a large hole at the top. This hole is called a crater. In a eruption, a volcano produces very hot, melted rock. - Magma: under the surface - Lava: on the surface A lava lake is a amount of lava forms in the crater. A volcano forms at an opening or vent, in the crust at the boundaries between plates.
A volcanic eruption occurs when one plate pull under the other. Water vapour, particles, gases ang magma pur out onto surface. Volcanoes form new land. Gases and particles from a volcano can affect the weather. The mantle is the layer of Earth under the crust. Some areas are very hot and volcanoes can form at these hot spots.
