Question

Tsunami is caused by

• A. plate tectonics
• B. underwater ridges
• C. underwater volcanic activity
• D. pressure from Earth’s core

Answer 1

The Correct Option is C

Tsunamis are primarily caused by underwater volcanic activity, along with other factors like earthquakes or underwater landslides. When there is a sudden displacement of a large volume of water, such as during an undersea volcanic eruption or a powerful earthquake, the water is pushed upward or displaced. This leads to the creation of waves that travel across the ocean at high speeds.

When these waves reach coastal areas, they can cause significant damage due to their immense energy and height. Tsunamis can result in devastating impacts on coastal communities, with waves often reaching several meters high. The phenomenon is commonly triggered by seismic activities such as earthquakes along tectonic plate boundaries or volcanic eruptions beneath the ocean floor.

The correct answer is: Underwater volcanic activity, as it can create the conditions necessary for tsunami formation by displacing large amounts of water.
