Question

A continuous period of dry weather in which area gets less than its normal amount of rain, over months or even years is known as:
A. Tsunami
B. Drought
C. Floods
D. Volcanic eruptions

Answer 1

Hint: Tsunami occurs when the ocean surface experiences sudden movement due to earthquakes or landslides. Drought occurs when any region experiences below average precipitation or very less amount of rainfall. Floods occur when heavy rainfall happens for a long period of time. Volcanic eruptions are caused due to rise in the level of molten rock.

Complete step by step answer:
When there is a lack of either snow or rain in an area or region, eventually the soil moisture reduces and the level of groundwater also decreases abruptly. The droughts result in diminished stream flow, crop damage and general water shortage. The temperature in such regions will be high.
Therefore, the correct option is option b.

Additional information:
Droughts are the second most costly weather events after hurricanes. Unlike other natural disasters like hurricanes, tornadoes and thunderstorms, one can’t know when a drought began or has ended. The intimal effects of drought are difficult to understand and it takes weeks or months to determine that drought has started. The end is also hard to identify for the same reason. Droughts sometimes last for more than a decade too. The more time the drought lasts, the greater harmful effects it has on people. People don’t get drinking water. Water is not available to grow crops and food. In such cases, irrigation is adopted. If drought acts long enough, the nearby water bodies also diminish and there will not be any other way to survive in such conditions.

Note:
Droughts are really dangerous and it’s the second costliest natural disaster. The most affected area due to droughts is the United states which is also called as dirty thirties. Sources tell that nearly fifty million acres of land were affected during those days. As it is harder to guess, the consequences are also deadly.
