NCERT Solutions for Class 8 Science Chapter 15
The chapter teaches class 8 students about how natural phenomena take place. It certainly makes them aware of the dangers of these natural phenomena. Furthermore, the chapter teaches students the precautions to take for these phenomena. Students also get information about the functioning of lightning and earthquakes. Above all, this chapter prepares students for multiple subjects. This is because natural phenomena is an important topic in many subjects. These subjects are Science, Geology, Geography, Climatology, and Meteorology.
Now there is a short discussion of the sub-units of this chapter:
15.1 Lightning – Lightning refers to electrostatic discharge. Furthermore, this electrostatic discharge happens naturally. Also, there is a release of an extremely huge amount of energy during lightning.
15.2 Charging by Rubbing – This is an electric phenomenon. In this phenomenon, friction transfers charged particles from one body to another.
15.3 Types of Charges and Their Interaction – This part contains types of charges. Furthermore, the discussion of the interaction of the charges is also here.
15.4 Transfer of Charge – Charge transfer happens through induction, conduction, or friction. Furthermore, a device known as electroscope detects charge.
15.5 The Story of Lightning – Here explanation of Lightning takes place. Above all, this explanation takes place in terms of the charges. The production of these charges is by rubbing.
15.6 Lightning Safety – Here, students learn safety measures. These precautions come into use during Lightning.
15.7 Earthquakes – Finally, this part is the last sub-unit. An earthquake is a sudden trembling of the Earth. Furthermore, this trembling movement lasts for a very short time.
