Understanding Tsunamis

A tsunami is a series of giant waves caused by energy transfer through water, often due to tectonic activity. Initially small, these waves travel quickly but grow in height as they approach the shore due to the rising seabed. The video explains the formation and characteristics of tsunamis, including the role of tectonic plates and energy flux.

What does the word 'tsunami' mean in Japanese?

• Sea Wave

• Ocean Wave

• Harbor Wave

• Giant Wave

What provides energy to water to form regular waves?

• Rain

• Tides

• Wind

• Sunlight

What happens when a tectonic plate slides beneath another on the ocean floor?

• A volcano erupts

• A tsunami is immediately formed

• The ocean floor rises

• An earthquake releases energy

Why do tsunami waves increase in height as they approach the shore?

• The water becomes deeper

• The seabed rises, slowing the waves

• The waves gain more energy

• The wind pushes them higher

What remains constant as the speed of tsunami waves decreases near the shore?

• Water temperature

• Wave frequency

• Energy flux

• Wave height
