Answer 1

Answer:

A. 1, 3

• Floods are natural disasters that occur when water inundates land that is normally dry. While they can be caused by various natural phenomena like heavy rainfall, overflowing rivers, and melting snow, human activities such as deforestation, urbanization, and inadequate drainage systems can exacerbate their impact and frequency. The severity of a flood depends on factors like topography, soil saturation, and the duration and intensity of rainfall.
