A flood is an overflow of water on land which is usually dry.

Sometimes a water resource (river, lake or pond) gets flushed with too much water. Unusually heavy rain sometimes causes floods. When there is too much water, it may overflow beyond its normal limits. This water then spreads over land, flooding it. Extreme flooding can also be caused by a tsunami or a large storm that causes a storm surge. Floods that happen quickly are called flash floods.

The most deadly flooding was in 1931 in China and killed between 2,000,000 and 4,000,000 people.The Kerela flood in India was another flood that has destroyed people's houses.

During a flood, people try to move themselves and their most precious belongings to higher ground quickly. The process of leaving homes in search of a safe place is called evacuation



Drought is a continuous period of dry weather, when an area gets less than its normal amount of rain, over months or even years. Crops and other plants need water to grow, and animals need it to live. Droughts can become dangerous to people and other land animals; causing famine and even creating deserts.

A drought is a natural event, caused by other weather events like El Niño and high-pressure systems. Drought can also be triggered by deforestation (people cutting down forests), by global warming, and by diverting rivers or emptying lakes.

Drought is a natural disaster which usually takes place slowly. It is often difficult to decide when a drought started and sometimes when it ends too. Its effects often build up slowly over a long period of time and may last from months to years after rain resumes.

Many people die every year in famines due to drought in subsistence farming areas. Conflicts can result from drought conditions
