When natural calamities occur, many people blame fate/God due to ignorance. But at the same time Science could not predict Earthquakes, Tsunamis, etc. It can only explain natural calamities. For example Plate Tectonics theory says Earthquakes occur at the plate boundaries. According to this theory, the earth is divided into 7 major plates and many minor plates. These plates move at a rate of 1cm/year. These movements cause Earthquakes, Volcanoes, etc.Thus Science explains many natural calamities and some can even be predicted by using science, for example the prediction of Cyclones, Landslides, etc.Science even advocates us the precautions to be taken.
If a student wants to succeed in an examination, he/she should work hard, i.e., prepare the examination in a planned/scientific way instead of leaving everything to God( some students pray to God for a pass in the examination), or being superstitious by under estimating himself/herself.
