What is a tsunami?

  1. A series of large waves caused by an underwater earthquake.

  2. A type of storm that forms over warm ocean waters.

  3. A sudden rise in sea level due to a change in atmospheric pressure.

  4. A powerful current that flows along the coastline.


Correct Option: A
Explanation:

Tsunamis are generated by sudden disturbances in the ocean, such as earthquakes, landslides, or volcanic eruptions. They consist of a series of large waves that can travel across entire ocean basins.

What is the difference between a tsunami and a storm surge?

  1. Tsunamis are caused by underwater disturbances, while storm surges are caused by strong winds.

  2. Tsunamis travel much faster than storm surges.

  3. Tsunamis can reach much higher heights than storm surges.

  4. All of the above.


Correct Option: D
Explanation:

Tsunamis are caused by underwater disturbances, while storm surges are caused by strong winds. Tsunamis travel much faster than storm surges, and they can reach much higher heights.

What are the characteristics of a tsunami?

  1. They can travel across entire ocean basins.

  2. They can reach heights of over 100 feet.

  3. They can cause widespread destruction and loss of life.

  4. All of the above.


Correct Option: D
Explanation:

Tsunamis are characterized by their ability to travel across entire ocean basins, their potential to reach heights of over 100 feet, and their capacity to cause widespread destruction and loss of life.

What are the impacts of a tsunami?

  1. Flooding and inundation of coastal areas.

  2. Damage to infrastructure and property.

  3. Loss of life and displacement of people.

  4. All of the above.


Correct Option: D
Explanation:

Tsunamis can cause flooding and inundation of coastal areas, damage to infrastructure and property, and loss of life and displacement of people.

What is a storm surge?

  1. A sudden rise in sea level caused by a storm.

  2. A type of wave that forms during a storm.

  3. A strong current that flows along the coastline.

  4. A change in atmospheric pressure that causes sea level to rise.


Correct Option: A
Explanation:

Storm surges are caused by the strong winds and low pressure associated with storms. They can cause sea level to rise by several feet, leading to flooding and inundation of coastal areas.

What are the characteristics of a storm surge?

  1. They can cause flooding and inundation of coastal areas.

  2. They can reach heights of over 20 feet.

  3. They can cause widespread destruction and loss of life.

  4. All of the above.


Correct Option: D
Explanation:

Storm surges are characterized by their ability to cause flooding and inundation of coastal areas, their potential to reach heights of over 20 feet, and their capacity to cause widespread destruction and loss of life.

What are the impacts of a storm surge?

  1. Flooding and inundation of coastal areas.

  2. Damage to infrastructure and property.

  3. Loss of life and displacement of people.

  4. All of the above.


Correct Option: D
Explanation:

Storm surges can cause flooding and inundation of coastal areas, damage to infrastructure and property, and loss of life and displacement of people.

How can we mitigate the impacts of tsunamis and storm surges?

  1. Building seawalls and levees.

  2. Developing early warning systems.

  3. Educating coastal communities about tsunami and storm surge risks.

  4. All of the above.


Correct Option: D
Explanation:

We can mitigate the impacts of tsunamis and storm surges by building seawalls and levees, developing early warning systems, and educating coastal communities about tsunami and storm surge risks.

What is the difference between a tsunami warning and a tsunami watch?

  1. A tsunami warning means that a tsunami is imminent or expected.

  2. A tsunami watch means that a tsunami is possible but not imminent.

  3. A tsunami warning is issued for coastal areas that are at risk of being hit by a tsunami.

  4. All of the above.


Correct Option: D
Explanation:

A tsunami warning means that a tsunami is imminent or expected, while a tsunami watch means that a tsunami is possible but not imminent. A tsunami warning is issued for coastal areas that are at risk of being hit by a tsunami.

What should you do if you are in a coastal area and a tsunami warning or watch is issued?

  1. Move to higher ground immediately.

  2. Stay indoors and away from windows.

  3. Turn off all utilities and appliances.

  4. All of the above.


Correct Option: A
Explanation:

If you are in a coastal area and a tsunami warning or watch is issued, you should move to higher ground immediately. You should also stay indoors and away from windows, and turn off all utilities and appliances.

What are some of the signs that a tsunami may be approaching?

  1. A sudden rise in sea level.

  2. A loud roar or rumbling sound from the ocean.

  3. A strong earthquake.

  4. All of the above.


Correct Option: D
Explanation:

Some of the signs that a tsunami may be approaching include a sudden rise in sea level, a loud roar or rumbling sound from the ocean, and a strong earthquake.

What is the difference between a tsunami and a rip current?

  1. Tsunamis are caused by underwater disturbances, while rip currents are caused by waves breaking on the shore.

  2. Tsunamis travel much faster than rip currents.

  3. Tsunamis can reach much higher heights than rip currents.

  4. All of the above.


Correct Option: D
Explanation:

Tsunamis are caused by underwater disturbances, while rip currents are caused by waves breaking on the shore. Tsunamis travel much faster than rip currents, and they can reach much higher heights.

What is the difference between a tsunami and a seiche?

  1. Tsunamis are caused by underwater disturbances, while seiches are caused by changes in atmospheric pressure.

  2. Tsunamis travel much faster than seiches.

  3. Tsunamis can reach much higher heights than seiches.

  4. All of the above.


Correct Option: D
Explanation:

Tsunamis are caused by underwater disturbances, while seiches are caused by changes in atmospheric pressure. Tsunamis travel much faster than seiches, and they can reach much higher heights.

What is the difference between a tsunami and a tidal wave?

  1. Tsunamis are caused by underwater disturbances, while tidal waves are caused by the gravitational pull of the moon and sun.

  2. Tsunamis travel much faster than tidal waves.

  3. Tsunamis can reach much higher heights than tidal waves.

  4. All of the above.


Correct Option: D
Explanation:

Tsunamis are caused by underwater disturbances, while tidal waves are caused by the gravitational pull of the moon and sun. Tsunamis travel much faster than tidal waves, and they can reach much higher heights.

What is the difference between a tsunami and a rogue wave?

  1. Tsunamis are caused by underwater disturbances, while rogue waves are caused by the interaction of multiple waves.

  2. Tsunamis travel much faster than rogue waves.

  3. Tsunamis can reach much higher heights than rogue waves.

  4. All of the above.


Correct Option: D
Explanation:

Tsunamis are caused by underwater disturbances, while rogue waves are caused by the interaction of multiple waves. Tsunamis travel much faster than rogue waves, and they can reach much higher heights.
