Explanation:
Floods and droughts: too much is like not enough ! ... Droughts occur when an abnormally long dry period uses up available water resources. Floods happen when watercourses or rain swallow up land that is usually uncovered. These natural disasters are often made worse by human action.
Answer:
A flood is an overflow of water that submerges land that is usually dry.[1] In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health.
Many countries that receive very little rain count on small downpours to water their crops. If the absence of rain lasts a few years, it can result in poor harvests and soil that can never recover its nutrients. In regions where the survival of inhabitants depends on agriculture, a lack of rain can be dramatic. Famine may occur, causing many deaths. In the last 50 years, the longest-lasting droughts and the most frequent famines have been in Africa. The drought that ravaged countries like Chad and Ethiopia from 1968 to 1988 killed thousands of people and forced millions of others to move to more humid regions.
