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 a volcanic eruption. When the eruption takes place, great clouds of ashes, dust, gas and steam rise from the crater. Loud noises come from the crater.

Answer:

1) A volcano is a mountain with a great hole running deep into the earth, from which smoke, gases, and stones can emerge.

2) A volcanic eruption is when a quiet volcano suddenly becomes active, releasing great clouds of ashes, dust, gas, and steam from the crater. White hot molten rock, called lava, can also flow down the mountain sides.

3)Lava refers to white hot molten rock that flows down the mountain sides during a volcanic eruption.

4) A crater is the mouth of the opening of a volcano.

Most volcanoes are found near the seas.

5) After a volcanic eruption, the after-effects can include damage to the surrounding environment and communities, including destruction of buildings and infrastructure, ashfall, and potential mudslides and floods.

6)The passage states that "Then the volcano will go to sleep again for many years," indicating that after a period of activity, a volcano can become quiet again for an extended period.

7) The passage begins with the sentence "A volcano is a burning mountain," indicating that the primary definition of a volcano is that it is a mountain with a great hole or opening.
