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, (a) volcanoes are formed
At convergent boundaries, (a) volcanoes are formed
Lava's resistance to flow is known as
(a)
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
At strato volcanoes, eruptions are explosive because the magma traps a lot of
Ash
Lava
Gas
Rocks

Shield
Strato
Pyroclasts refer to
Lava
Hot rock fragments and superheated gases
Lava and water mixture
Ash and rock fragments
