Floods are usually caused by heavy rains that pour a lot of water into rivers together with other waterways, making these natural paths unable to carry all the water. As a result, rising water flows over or smashes the banks to the waterways making the surrounding land to be flooded.
Floods happen when there is so much rain that lakes, ponds and rivers overflow because they fill up too much. Some places are more notorious for flooding and are known as flood zones.
