Question

Describe on volcanic eruption you may have seen on T.V.

​

Answer 1

Answer:

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-oceanic ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande Rift in North America.

Explanation:

A volcanic eruption occurs when magma is released from volcano. Volcanic eruptions can be quite calm and effusive, or they can be explosive . Effusive eruptions produce lava flows, while explosive eruption produce ash and pyroclastic density currents
