Explanation: Separated charges build up in clouds; a large enough charge jumps across as lightning.
- Q4 of 6Medium
How does a lightning conductor protect a building?
Show answerHide answer
Answer: It provides an easy metal path to carry the lightning's charge safely to the ground
Explanation: The conductor guides the charge straight to earth, so it does not damage the building.
- Q5 of 6Hard
Why are some parts of India, like the Himalayan belt and Kutch, more earthquake-prone than others?
Show answerHide answer
Answer: They lie along active plate boundaries (seismic zones) where the crust is unstable
Explanation: These regions sit on active fault/seismic zones where plate movement frequently triggers quakes.
- Q6 of 6Hard
A metal sphere on an insulating stand is charged, then touched with a wire connected to the ground. The sphere loses its charge because:
Show answerHide answer
Answer: The charge flows through the wire to the earth (earthing)
Explanation: The conducting wire earths the sphere, letting its charge flow to the ground.
Some Natural Phenomena notes: key concepts (Class 8 Science)
This chapter covers two natural phenomena linked to charge and Earth's interior — lightning (static electricity) and earthquakes.
- Charging by rubbing
- Rubbing transfers charge; like charges repel and unlike charges attract (tested with an electroscope).
- Electric discharge & lightning
- Lightning is a large electric discharge between charged clouds (or cloud and ground).
- Lightning safety
- Take shelter indoors; lightning conductors on tall buildings safely carry the charge to the ground.
- Earthquakes
- Sudden shaking of the ground caused by movement of tectonic plates along fault lines.
- Seismic measurement & safety
- Earthquakes are recorded by a seismograph and rated on the Richter scale; quake-resistant buildings reduce damage.
