Question

speech on volcanic eruptions

Answer 1

Step-by-step explanation:

A volcanic eruption occurs when hot materials from the Earth's interior are thrown out of a volcano. Lava, rocks, dust, and gas compounds are some of these "ejecta". Eruptions can come from side branches or from the top of the volcano.

Answer:

A volcano is a mountain that has lava (hot, liquid rock) coming out from a magma chamber under the ground, or that has had that in the past. Volcanoes are formed by the movement of tectonic plates. Most volcanoes have a volcanic crater at the top. ... When there is enough pressure, the volcano erupts.
