A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from the magma chamber below the surface. Volcanoes are generally found …

Volcanoes form when parts of the Earth’s solid mantle melts to form pockets of hot liquid rock called magma. This magma collects in large pools deep underground known as magma chambers.

For each type of plate boundary and hotspots be able to predict: the resulting geographic pattern of volcanoes on Earth’s surface what type of magma will form and why what type of volcano …

• The two principal types of volcanoes are shield and strato (or composite volcanoes). The two principal styles of volcanism are effusive and explosive. • The three Vs (volumes, volatiles, viscosity) …

Unlike stratovolcanoes that are composed of viscous lavas and ash, shield volcanoes are made of fluid basalt lavas flows, that flow much further, thus giving them their characteristic shield-like shape.

Volcanic eruptions can trigger floods, landslides, mudslides, and wildfires.1 Additional information about these hazards is available through their respective factsheets. In addition, “laze” (lava + haze) can …
