Science Some Natural Phenomena Pdf The cbse class 8 science (physics) some natural phenomena worksheet (ncert) helps students understand the causes and effects of natural events such as lightning and earthquakes. it includes concept based questions on electric charges, charge transfer, the working of an electroscope, and lightning safety measures. students also explore how earthquakes occur, their measurement using the richter. In this chapter we shall discuss two other destructive natural phenomena. these are lightning and earthquakes. we shall also discuss what steps we can take to minimise destruction caused by these phenomena. 15.1 lightning. you might have seen sparks on a electric pole when wires become loose. Earthquakes occur all the time all over the world. the plates of the outermost layer of the earth are always in continuous motion. tremors on the earth can also be caused by the eruption of a volcano. the process of electric discharge cannot occur between clouds and the earth. bathing outdoors should be avoided during thunderstorm. 12. Epicentre: a point on the earth above the seismic force. fault zones: earthquake prone areas in the earth’s crust.
