B Correct answer
Explanation

  Flood forecasting has been recognized as one of the most important, reliable and cost-effective non-structural measures for flood management.

Central Water Commission started flood-forecasting services in 1958 with the setting up of its first forecasting station on Yamuna at Delhi Railway Bridge.  Presently, a network of 175 Flood Forecasting Stations including 28 inflow forecast, in 9 major river basins and 71 sub basins of the country exists. It covers 15 States besides NCT Delhi and UT of Dadra & Nagar Haveli. Central Water Commission on an average issues 6000 flood forecasts with an accuracy of more than 95% every year.

A Correct answer
Explanation

Underwater earthquakes push water upward to create the initial movement, then gravity pulls the water downward, creating the horizontal force that forms the tsunami. The waves travel through the ocean in a similar fashion to ripples created by throwing a stone into a body of water.

Earthquakes occur often on the earth's crust that forms the sea floor; however, not all result in a tsunami. For a tsunami to form, the magnitude of the earthquake must measure a minimum of 7.0 on the Richter scale. Below this magnitude, the earthquake does not displace enough water to create the big wave. The movement must also lift or lower the sea bed. Sideways movement does not create the initial wave to start the process. The epicenter of the earthquake must be near the surface of the sea floor to cause the correct movement.

A Correct answer
Explanation

Rainfall over an extended period and an extended area can cause major rivers to overflow their banks. The water can cover enormous areas. Downstream areas may be affected, even when they didn’t receive much rain themselves. High amounts of water flowing in streams often leads to flooding, and flooding is one of the more common types of natural disasters. A flood results when a stream runs out of its confines and submerges surrounding areas.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • An Earthquake at the bottom of ocean can cause large scale displacement of water leading into very high harbour waves called Tsunami. Tsunamis can in turn cause large scale flooding of the coastal areas. 
  • Also Earthquakes the shaking of the mountaneous regions caused by earthquakes can cause landslides. Hence earthquakes can cause tsunami,flooding and landslides. 
  • Lightening is an atmospheric phenomenon, hence is unrelated to earthquake.
