The volcano is an elevated structure through which the flows out and cools down and forms a rock
the volcano is of 3 types
Active volcano
dormant volcano
Extinct volcano
when there is a large amount of gas released from the volcano it indicated that the volcano may erupt in the future as the gas may be released from any chemical reaction the stopping of the gas shows the chemical reaction which took place is over or slowed down but it denotes in the near future the volcano my erupt and can cause destruction
hence it is concluded that the dormant volcano can become active with the passage of time

Answer:B
Explanation:Its your own culture so nothing should really affect
Answer:
A. Rock is heated near the core at Point A, and therefore becomes less dense. It rises towards Point B. As it moves from Point B to Point C, it is cooled and becomes denser, so it sinks at Point D.
Explanation:
The process illustrated is a convection current, something seen places like the earth's mantle and atmosphere. The hotter matter gets, the more excited its molecules become and the more they become expanded and distant from each other. (Bear in mind that there is the same amount of matter but it takes up more space, i.e. less dense). This is because the molecules are excited by the thermal energy and bounce off each other, pushing them apart.
Cold, closer to the surface (or outer space in terms of air), in turn causes the matter to shrink back into itself, which leads to the increase in density that causes it to sink and repeats the process.
