Short note on natural catastrophe and harnessing technology
Answers
Natural catastroph is an unexpected event caused by nature, such as erthquake or flood.It cause loss of life or property damage. For example earthquake in Nepal during 2015, have disasterous consequences and leave lasting damage, volcanic eruption which cause explosion of the volcano or falling rock, lava is produce during volcanic eruption which destryos many building, plants and animals, and it also produce volcanic ash, form a cloud and settle thickly in near locations. In 1953 Tangiwai disaster was caused by a lahar, in 1985 Armero tragedy in which the town of Armero was buried and anb estimated 23,000 people were killed, flood is temporary covering of land with water, which is a result of increase in volume of water and get overflow causing some of water to escape its usual boundaries. Tsunami is a seismic sea wave or as tidal wave which cause displacement of a large volume of water in an ocean or large lake, in 2011 tsunami occured near Fukushima Japan.
Harnessing technology is a technique produce by the learning and skill improvement service (LSIS). these case studies describe work done by practitioners to harness technology in STEM teaching and learning.
