Statement 1: Floods caused due to heavy rainfall is a man-made cause.
Statement 2: Floods are only caused by natural events.

The correct option is A Both statements are false.
Floods occur when the accumulation of excess water causes normally dry land to get submerged underwater. A flood can occur due to a number of reasons. Causes of floods can be broadly classified into two classes: natural and man-made. Floods that are usually caused due to persistent rains, overflowing of rivers, or any other water body can be termed as a natural flood. If a tank in a locality explodes leading to flooding of water in an area, it is termed as a man-made flood.
