VolcanoesVolcanoes
• 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.
