Tsunamis and Typhoons Quiz

What is the initial event that triggers a tsunami?

• Heavy rainfall

• Volcanic eruption on land

• Sudden movement of tectonic plates displacing the seafloor

• Strong winds creating large waves

What happens immediately after the seafloor is displaced?

• The water evaporates.

• A massive amount of water is pushed upward.

• The ocean floor collapses.

• The waves immediately crash onto land.

How does the energy from the displaced water travel across the ocean?

• In a circular motion, like a whirlpool.

• In a single, focused beam.

• Through the formation of tsunami waves that move in all directions.

• By creating a large, stationary wave.

What occurs when tsunami waves enter shallow waters?

• They speed up and decrease in height.

• They maintain their speed and height.

• They slow down and increase in height.

• They disappear entirely.

What is the final stage of a tsunami's progression?

• The waves dissipate in the deep ocean.

• The waves freeze into ice.

• The waves crash onto land, causing destruction and flooding.

• The waves turn into a gentle swell.

The 'FORMATION' stage of a tsunami involves:

• Waves crashing onto land.

• Water being pushed upward.

• Energy traveling through the ocean.

• Tectonic plates moving.

The 'APPROACH' stage is primarily characterized by changes in the wave's:

• Temperature and color.

• Speed and height.

• Chemical composition.

• Sound and smell.

Which of the following correctly orders the stages of tsunami formation?

• Impact, Approach, Formation, Build, Activation

• Activation, Build, Formation, Approach, Impact

• Formation, Build, Activation, Impact, Approach

• Approach, Impact, Activation, Build, Formation

What are faults?

• Layers of sediment in the Earth's mantle.

• Fractures or breaks in the Earth's crust.

• Areas of volcanic activity on the surface.

• Underground rivers and aquifers.

What is faulting?

• The process of erosion on rock formations.

• The formation of magma chambers beneath volcanoes.

• The movement or displacement of rock masses in the crust.

• The creation of sedimentary layers through deposition.
