Can you volcano?

Volcanoes can be found in all these boundaries except transform boundaries and

• O-O Divergence

• O-C Convergence

• C-C Convergence

• C-C Divergence

The bowl shaped opening at the end of the pipe of a volcano is known as

• Crater

• Vent

• Magma chamber

• Cone

1. Magma rises to the surface through the vent, and onto the surface as lava.

2. New eruptions of lava covers the ash layer and builds up the volcano.

3. Magma rises from the mantle's magma chamber to the crust through fractures in the crust.

4. Lava builds up around the vent, solidifying to form a small volcanic cone. The bowl-shaped opening is called a crater.

At divergent boundaries, _____ volcanoes are formed

At convergent boundaries, ______ volcanoes are formed

Lava's resistance to flow is known as

Strato volcanoes have all these characteristics except

• Narrow base

• Low viscosity lava

• Steep Gradient

• Explosive eruptions

Shield volcanoes have all these characteristics except

• Broad base

• Low viscosity lava

• Gentle Gradient

• Very tall volcanoes

At strato volcanoes, lava is viscous because it contains more

• Plate material

• Silica

• Molten rock

• Ash
