Earthquakes and Building Structures

What causes earthquakes?

• The shaking of the ground

• The collision of two plates on the Earth's surface

• The movement of tectonic plates

• The rubbing together of two plates on the Earth's surface

What is soil liquefaction?

• The process of turning soil into liquid

• The sinking of heavy objects during an earthquake

• The hardening of soil after an earthquake

• The separation of sand particles during an earthquake

What is the purpose of a seismometer?

• To measure the direction of an earthquake

• To predict the occurrence of an earthquake

• To measure the intensity of an earthquake

• To measure the vibrations caused by an earthquake

What is the advantage of using a triangle shape in building structures?

• It provides stability and prevents swaying

• It allows for flexibility and absorbs vibrations

• It increases the weight-bearing capacity

• It improves the overall aesthetics

What happens during soil liquefaction?

• The ground turns into liquid

• The ground becomes more solid

• The ground sinks and hardens

• The ground separates into layers

What is the purpose of cross braces in building structures?

• To increase the weight-bearing capacity

• To provide stability and prevent swaying

• To absorb vibrations and increase flexibility

• To improve the overall aesthetics

What is the main goal of building structures in earthquake-prone areas?

• To withstand the shaking of an earthquake

• To predict the occurrence of an earthquake

• To prevent the occurrence of an earthquake

• To minimize the damage caused by an earthquake

What is the purpose of a Shaker table in earthquake experiments?

• To simulate the shaking of an earthquake

• To measure the intensity of an earthquake

• To predict the occurrence of an earthquake

• To analyze the effects of an earthquake

What is the role of bungee cords in building flexible structures?

• To increase the weight-bearing capacity

• To provide stability and prevent swaying

• To absorb vibrations and increase flexibility

• To improve the overall aesthetics

What is the purpose of platforms in earthquake building designs?

• To increase the weight-bearing capacity

• To provide stability and prevent swaying

• To absorb vibrations and increase flexibility
