Detailed explanation-1: -When magma erupts at the surface as lava, it can form different types of volcano depending on: the viscosity, or stickiness, of the magma. the amount of gas in the magma. the composition of the magma.
Detailed explanation-2: -Volcanic eruptions can be explosive, sending ash, gas and lava high up into the atmosphere, or the magma can form lava flows, known as effusive eruptions. Whether an eruption is explosive or effusive largely depends upon the amount of gas in the magma.
Detailed explanation-3: -Magma composition determines both eruption type and volcano type. Composite volcanoes are common at convergent boundaries. Shield volcanoes are produced at divergent plate boundaries and intraplate. Cinder cones are made of small fragments of a variety of compositions usually from a single eruption.
