Ответ от Condorita[гуру]
Как образуется вулкан? (именно так будет по-русски, а не по тарабарски)
Cлово TO CREATE может обозначать не только СОЗДАВАТЬ, но и ОБРАЗОВЫВАТЬСЯ, если речь идет о природных объектах

A volcano is a vent through which molten rock known as magma rises, from inside the Earth, out onto its surface. Magma erupting from a volcano is called lava. When the spilled lava cools down and solidifies, it forms the mound-like cone around the vent of volcano. Many people think that a volcano is in fact a mountain from which lava erupts. However, now you know that the 'mountain' is in fact nothing but a cone of solidified lava from previous volcanic eruptions.
Volcanoes are usually termed as active, dormant or extinct. An active volcano is one that is erupting lava, generating seismic activity or releasing gas. On the other hand, a dormant volcano is one that has not erupted for a very long time, but could erupt again in the future. Finally, a volcano that has been dormant for more than 10,000 years is called extinct volcano. For volcanoes to be categorized this way requires extensive research and record-keeping. This was difficult in the old times, but is now easy due to computerization.
Volcanoes are quite different in appearance, with some having perfect cone shapes while others having deep depressions filled with water. The form of a volcano points to the type and size of its eruption; this in turn is controlled by characteristics of the magma, particularly its composition.
