• A. രണ്ടും മൂന്നും
• B. രണ്ട് മാത്രം
• C. ഒന്നും മൂന്നും
• D. ഒന്നും രണ്ടും

Answer 1

Answer:

A. രണ്ടും മൂന്നും

While all flash floods are floods, not all floods are flash floods. The key distinction lies in the speed of their onset and the intensity of water flow. General floods can develop over longer periods due to prolonged rainfall, melting snow, or dam breaches, often leading to widespread but slower inundation. Flash floods, conversely, are typically localized but extremely violent, posing immediate threats due to their rapid development and the force of the water. This differentiation is important for emergency services to tailor their response and warning systems appropriately.
