Volcanoes are formed when two tectonic plates in the earth come together. They push together and as they do, it pushes land upward, creating a mountain. It becomes a volano when magma form the earth's mantle rises up the centre of the vocano, and breaks through the top.

Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts. If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises. When the pressure is too much an explosive eruption can happen.

Why does the homemade volcano erupt?
Homemade volcanoes are made from vinegar and baking soda. It "erupts" because as the vinegar and baking soda come into contact with each other, a chemical reaction takes place which causes it to fizz.
What is a volcano that does not erupt called?
It can be called an active, dormant or extinct volcano. An active volcano erupts regularly and frequently, however, it might not erupt at some times. A dormant volcano rarely erupts. Therefore, it does not erupt for most of the time. An extinct volcano does not erupt anymore.

What causes the difference between quiet and exploses eruptions?
It depends on how much silica is in the magma. If there is low-silica in the magma then the volcano will erupt quietly. If there is high-silica in the magma then the volcano will erupt explosively.

Why do you think earthquakes are likely to occur at the same time when the volcano is about to erupt?
In order for a volcano to erupt, magma must move toward the surface. This causes rock to shift and break underground, generating earthquakes.
