Earthquake Quiz

What is the main difference between the Modified Mercalli Intensity scale and the Richter magnitude scale?

• Stupika and Parees are debating about whether Mercalli scale measures earthquake magnitude, while Richter scale measures intensity at a specific location.

• Kavya wants to know if Mercalli scale measures wind speed, while Richter scale measures earthquake depth.

• Jaison, Sarthak, and Stupika are discussing if Mercalli scale measures the Richter scale, while Richter scale measures the Mercalli scale.

• Stupika and Parees are curious to know if Mercalli scale measures intensity at a specific location, while Richter scale measures earthquake magnitude.

How does the Modified Mercalli Intensity scale assess the effects of an earthquake on people, buildings, and the environment? Share your thoughts with Midhansh, Kavya, and Stupika.

• It evaluates the observed damage to people, buildings, and the environment.

• It measures the economic impact of the earthquake

• It determines the depth of the earthquake's epicenter

• It assesses the earthquake's magnitude on the Richter scale

During a recent earthquake, Aadhya asked her teacher how the Richter magnitude scale measures the energy released. What would be the teacher's correct response?

• By analyzing the color of the sky during the earthquake

• By counting the number of aftershocks

• By using the amplitude of seismic waves

• By measuring the depth of the earthquake's epicenter

During a recent earthquake, how does the Modified Mercalli Intensity scale classify the intensity based on observed effects and damage to structures?

• By the depth of the earthquake's epicenter

• Based on the earthquake's magnitude

• According to the earthquake's location on the Richter scale

• Based on observed effects and damage to structures

How would you explain the process of measuring earthquake intensity using the Mercalli scale to Jaison, Midhansh, and Spandan in a fun and engaging way?

• By counting the number of aftershocks

• By analyzing the seismic waves in the Earth's crust

• By observing and recording the effects of the earthquake on people, buildings, and the natural environment.

• By measuring the earthquake's magnitude on the Richter scale

During a recent science class, Sarthak, Stupika, Arya, Kavya, and Vishnay were discussing the key factors that determine the magnitude of an earthquake according to the Richter scale. What are these key factors?

• Time of day and weather conditions

• Energy released and amplitude of seismic waves

• Number of aftershocks and distance from the epicenter

• Depth of the earthquake and duration of the shaking

During an earthquake, what should Nirmiti, Jaison, and Vishnay do to stay safe and protect themselves and others?

• Stand near a window to watch the earthquake

• Drop, cover, and hold on

• Run outside as fast as possible

• Ignore the shaking and continue with normal activities

During an earthquake, how well do Spandan, Parees, and Deven know the 'Drop, Cover, and Hold On' technique and why it is important?

• Ignore the shaking and continue with your activities

• Run outside as fast as possible

• It is important during an earthquake to protect yourself from falling objects and debris.

• Stand near a window to see what's happening

What should Sarthak, Vishnay, or Arya do if they are indoors during an earthquake and cannot find cover under a sturdy piece of furniture?

• Stand in a doorway

• Run outside as fast as possible

• Drop to the ground, take cover against an interior wall, and protect your head and neck with your arms.

• Climb under a heavy piece of furniture

What is the outer layer of the Earth called?

• Crust

• Lithosphere

• Mantle

• Core
