The correct answer is: a) Tsunamis.
Tsunamis are large waves in the ocean that are caused by earthquakes, volcanic eruptions, or landslides. They can travel at speeds of up to 800 kilometers per hour and can reach heights of up to 30 meters. Tsunamis can cause extensive damage to coastal areas, including flooding, erosion, and loss of life.
Earthquakes are the shaking of the ground caused by the sudden release of energy in the Earth’s crust. They can occur anywhere on Earth, but are most common in areas where tectonic plates meet. Earthquakes can cause a variety of damage, including building collapse, landslides, and tsunamis.
Landslides are the movement of a mass of rock, soil, or debris down a slope. They can be caused by a variety of factors, including earthquakes, heavy rains, and human activity. Landslides can cause extensive damage to property and infrastructure, and can also result in loss of life.
Volcanic eruptions are the release of molten rock, ash, and gas from a volcano. They can occur on land or under the ocean. Volcanic eruptions can cause a variety of damage, including flooding, erosion, and loss of life.
Tamil Nadu is a state in India that is located on the Bay of Bengal. The state has a long coastline, and is therefore vulnerable to tsunamis. In 2004, the Indian Ocean tsunami caused extensive damage to the state’s coastal areas.
