Tsunamis and Plate Motion Quiz

What is a tsunami?

• A large, destructive ocean wave caused by a sudden shift in the seafloor

• A wave caused by wind at the ocean's surface

• A fast-rising tide or flood

• A wave that affects only the surface of the water

What can cause a tsunami?

• Underwater earthquakes

• Wind at the ocean's surface

• Underwater landslides

• Volcanic eruptions

How do tsunami waves differ from wind-driven ocean waves?

• Tsunami waves are faster, longer, and taller

• Tsunami waves are slower, shorter, and smaller

• Tsunami waves are the same as wind-driven waves

• Tsunami waves only affect the surface of the water

What happens to tsunami waves as they approach the shore?

• They slow down and increase in height

• They speed up and decrease in height

• They stay the same speed and height

• They disappear

What determines the amount of damage a tsunami can cause?

• The strength and location of the earthquake or event that caused the tsunami

• The size of the tsunami wave

• The speed of the tsunami wave

• The time of day the tsunami occurs

What is the main factor that determines whether an earthquake will cause a tsunami?

• The magnitude and location of the earthquake

• The time of day the earthquake occurs

• The depth of the earthquake

• The duration of the earthquake

What type of plate boundary is most likely to cause a tsunami?

• Convergent

• Divergent

• Transform

• None of the above

What happens at a convergent plate boundary?

• One plate moves under the other

• Two plates move away from each other

• Two plates slide past each other

• Two plates collide and form mountains

What happens at a divergent plate boundary?

• Two plates move away from each other

• One plate moves under the other

• Two plates slide past each other

• Two plates collide and form mountains

What happens at a transform plate boundary?

• Two plates slide past each other

• Two plates move away from each other

• One plate moves under the other

• Two plates collide and form mountains
