NATURAL DISASTERS
Drought and Flood

WHAT IS NATURAL DISASTER?

A natural disaster is a major
adverse event resulting from
natural processes of the Earth.

Natural disasters are changes
which are so great they may
cause damage to the shape of

the land or to the lives of
people and other living things.

WHAT IS DROUGHT?

A drought is a period of time when an area or region experiences below-normal
precipitation. The lack of adequate precipitation, either rain or snow, can cause
reduced soil moisture or groundwater, diminished stream flow, crop damage, and
a general water shortage. Droughts are the second-most costly weather events

after hurricanes.

Effect of DROUGHT:

Dry wind Shortage of
Hot water

Causes of Drought High
Temperature

What is Flood?

It is a natural event or occurrence where a piece
of land (or area) that is usually dry land, suddenly
gets submerged. Some floods can occur
suddenly and recede quickly. Others take days or
even months to build and discharge. When floods
happen in an area that people live, the water
carries along objects like houses, bridges, cars,
furniture, and even people. It can wipe away
farms, trees, and many more heavy items.



Flooding from
groundwater can
happen when the level
of water within the rock
or soil underground –
known as the water
table – rises. When the
water table rises and
reaches ground level,
water starts to seep
through to the surface
and flooding can
happen.
