Explanation:

Himachal Pradesh Chief Minister Jai Ram Thakur on August 20, 2022 expressed concern over the loss of life and property due to torrential rains and flash floods in various parts of Himachal Pradesh, in which 21 people were feared dead.

• Excessive or continuous rainfall over a period of days, or during particular seasons can lead to stagnation of water and cause flooding.
• Flash floods refer to such a situation, but occurring in a much shorter span of time.
• For instance, the US’s meteorological agency, the National Weather Service, says flash floods are caused when rainfall creates flooding in less than 6 hours.
• It adds that flash floods can also be caused by factors apart from rainfall, like when water goes beyond the levels of a dam.

Hence both statements are correct.
