The correct answer is: d) All of the above.
Tamil Nadu’s coastline is vulnerable to cyclones, tsunamis, and coastal erosion.
Cyclones are tropical storms that form over warm ocean waters. They can cause heavy rains, strong winds, and storm surges. The state of Tamil Nadu has been hit by several cyclones in recent years, including the 2013 Cyclone Phailin and the 2018 Cyclone Gaja.
Tsunamis are large waves that are caused by earthquakes or volcanic eruptions. They can travel at speeds of up to 800 kilometers per hour and can cause extensive damage when they hit land. The state of Tamil Nadu was hit by a tsunami in 2004, which caused widespread damage and loss of life.
Coastal erosion is the process of land being worn away by the sea. It can be caused by waves, tides, and currents. The state of Tamil Nadu has a long coastline, which is vulnerable to coastal erosion.
The state government has taken some measures to protect the coastline from these hazards, but more needs to be done.
