2. What are the three destructive natural phenomena according to Chapter 15 of Class 8 Science?
Cyclones, earthquakes, and lightning are the three major destructive phenomena. They have the capacity to cause severe damage and displace human habitats. Human life is also at stake during the occurrence of those destructive phenomena. To safeguard lives and provide humanitarian relief, adequate steps need to be taken to minimise the damage caused by these natural calamities. These steps have been discussed in detail on Vedantu.
3. What do you mean by natural phenomena according to Chapter 15 of Class 8 Science?
Natural phenomena are those that occur in nature without any human interference. Through the course of Chapter 15 of NCERT Class 8 Science, seven sub-topics are discussed in depth. These include the causes, effects, properties, and magnitude of some destructive natural phenomena like lightning and earthquakes. Functions of the electroscope are discussed and some steps to minimise the damage caused by these disastrous events are dealt with.
4. What is the name for the natural phenomenon taking place due charging by induction according to Chapter 15 of Class 8 Science?
In the process of induction, a charged object is brought near to but not touched to a neutral conducting object. When the object gets charged by induction, a reversal in the nature of charges occurs. A natural phenomenon that occurs due to the principle of induction is lightning. Electric discharge leads to the formation of streaks of bright light and the generation of loud sound.
5. What is discharge according to Chapter 15 of Class 8 Science?
Lightning is an example of electric discharge. We have seen that the positive charges collect near the upper edges of the clouds while the negative charges accumulate near the lower edges. When the magnitude of the accumulated charges becomes very large, the surrounding medium containing air is no longer able to resist their flow. This leads to electric discharge or lightning.
