Question

A volcano is a burning mountain with a great hole running deep into the earth. Out of it comes smoke, gases and

stones. The mouth of the opening is called the crater of the volcano.

Volcanoes are not always burning. Sometimes a volcano will remain quiet for centuries. And then it will suddenly

become active. This is called volcanic eruption.

When the eruption takes place, the great clouds of ashes, dust, gas and steam rise up from the crater. After sometime,

white hot molten rock, called lava begins to flow down the mountain sides.This may go on for days or weeks. Then the

volcano will remain quiet for many years. Most volcanoes are found near the seas.

c) Lava refers to______________.

d) A crater is the mouth of the______________.

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. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle
