RBSE Class 8 Science Chapter 15 Notes Some Natural Phenomena

→ There are two types of charges : positive charge and negative charge. Opposite charges attract and like charges repel each other.

→ Charges produced due to rubbing are called static charges, and flow of charges is called electric current. Electric charge is detected using electroscope.

→ The process of electric discharge that occur between two or more clouds or between clouds and the earth produces lightning. Lightning conductors protect high buildings from the effect of lightning.

→ Sudden trembling and shaking of the earth’s surface is called earthquake. Boundaries of the earth's plates are the places where earthquakes are most likely to occur. These boundaries are known as faults zones.

→ Destructive energy of an earthquake is measured on ‘Richter Scale’. Earthquakes with a magnitude 7 or more on Richter scale can destroy life and property to a great extent.
