Natural calamities are the phenomenon which can’t be prevented, but we can take precautions. Natural Calamities such as Floods, Tornadoes, Volcanic Eruptions, Tsunamis, Earthquakes, causes disturbance to our day-to-day life. Today, with the help of Science and Technology, we may be able to counteract these natural events and avoid disasters, or even reduce its impact on people.
Tornadoes & Hurricanes
A Tornado is a violently rotating column of air extending from within a thundercloud down to ground level. The strongest tornadoes may sweep houses from their foundations, destroy brick buildings, toss cars and school buses through the air, and even lift railways from their tracks.
Floods mean an increase in water level in an area due to heavy rainfall or melting snow.
Floods are the natural disaster caused due to overflow of rivers due to heavy rainfall or melting of snow which causes a large destruction in cities and villages.
Shaking of the Earth’s surface caused by rapid movement of the Earth’s rocky outer layer is known as an Earthquake. Earthquakes occur when energy stored within the Earth, usually in the form of strain in rocks, is suddenly released.
What do you mean by Geophysics?
Geophysics is a branch of science that applies physical principles to the study of the earth. Geophysicists examine physical phenomena and their relationships within the earth; such phenomena include the earth’s magnetic field, heat flow, the propagation of seismic (earthquake) waves, and the force of gravity
Subdivision of the wide-ranging subject matter of geophysics into various branches involves categorizing specific endeavors. Strictly speaking, however, the discipline embraces all fields devoted to researching the earth’s interior, atmosphere, hydrosphere, and ionosphere.
