Agenda - Earthquakes, Tsunamis, and Volcanism

Define earthquakes.

• Earthquakes are sudden and violent shaking of the ground, often caused by movements of the Earth's tectonic plates.

• Earthquakes are gentle breezes that cool the environment.

• Earthquakes are the process of water turning into vapor.

• Earthquakes are the growth of plants in the spring season.

What are the causes and consequences of earthquakes?

• Causes of earthquakes include tectonic plate movements, volcanic activity, and human activities. Consequences can include ground shaking, destruction of buildings, tsunamis, and loss of life.

• Causes of earthquakes include rainfall, wind patterns, and seasonal changes. Consequences can include increased plant growth, animal migration, and improved air quality.

• Causes of earthquakes include solar flares, lunar eclipses, and star movements. Consequences can include changes in weather, auroras, and longer days.

• Causes of earthquakes include ocean currents, cloud formation, and temperature changes. Consequences can include more rainfall, droughts, and snowstorms.

Explain what tsunamis are.

• Tsunamis are large ocean waves usually caused by underwater earthquakes or volcanic eruptions.

• Tsunamis are small ripples formed by wind blowing over the ocean surface.

• Tsunamis are tidal waves caused by the gravitational pull of the moon.

• Tsunamis are ocean currents that flow from the equator to the poles.

What are the impacts of volcanic eruptions?

• Impacts of volcanic eruptions include lava flows, ash clouds, destruction of habitats, and changes to the climate.

• Volcanic eruptions only result in the formation of rainbows and increased plant growth.

• Volcanic eruptions have no effect on the environment or climate.

• Volcanic eruptions cause only minor temperature drops and no other changes.

Describe the interconnections between earthquakes, tsunamis, and volcanism.

• Earthquakes can trigger tsunamis and volcanic eruptions. Volcanic eruptions can also cause earthquakes. These natural events are interconnected through tectonic activity.

• Earthquakes and tsunamis are unrelated to volcanism and occur independently of each other.

• Tsunamis are only caused by underwater landslides and have no connection to earthquakes or volcanism.

• Volcanic eruptions are caused solely by weather changes and are not linked to earthquakes or tsunamis.

An earthquake occurs when there is a sudden release of energy in the Earth's crust, often due to the movement of _________?

• tectonic plates

• clouds

• rivers

• mountains

How are earthquakes caused?

• By the rapid movement of tectonic plates

• By volcanic eruptions only

• By heavy rainfall

• By human construction

What is an example of a major earthquake mentioned in the text?

• The 2010 earthquake in Haiti, which devastated the capital, Port-au-Prince.

• The 2004 earthquake in Tokyo, Japan.

• The 2015 earthquake in San Francisco, USA.

• The 2012 earthquake in Sydney, Australia.

Which of the following is NOT a type of plate movement shown in the diagram?

• Lateral sliding

• Spreading

• Subduction

• Folding

Fill in the blank: The rapid movement of tectonic plates generates ________, resulting in tremors of varying intensity.

• seismic waves

• ocean currents

• magnetic fields

• volcanic ash
