The correct answer is a) Flash floods.
Flash floods are a sudden rise in water level in a stream, river, or other body of water. They can occur as a result of heavy rainfall, melting snow, or an ice jam. Flash floods can cause extensive damage to property and infrastructure, and can also lead to loss of life.
The Western Ghats are a mountain range that runs along the western coast of India. The region receives high levels of rainfall, which can lead to flash floods. In 2018, for example, heavy rains caused flash floods in the Western Ghats, killing at least 200 people and displacing thousands more.
Avalanches are a mass of snow, ice, and rock that slides down a mountain slope. They can be triggered by a number of factors, including heavy snowfall, earthquakes, and volcanic eruptions. Avalanches can cause extensive damage to property and infrastructure, and can also lead to loss of life.
Tsunamis are a series of waves that are caused by a disturbance in the ocean, such as an earthquake, volcanic eruption, or landslide. Tsunamis can travel at speeds of up to 800 kilometers per hour, and can cause extensive damage to coastal areas.
Sandstorms are a type of dust storm that occurs in dry, sandy areas. They can be caused by a number of factors, including high winds, dry weather, and human activity. Sandstorms can reduce visibility and cause respiratory problems.
In conclusion, the correct answer to the question “Which natural hazard is a result of high-intensity rainfall in the Western Ghats region?” is a) Flash floods.
