CKLA Unit 5 Chapter 3

What is the epicenter of an earthquake?

• The point on Earth's surface directly above the earthquake's focus
• The location where the earthquake occurred
• The deepest point of the earthquake's focus
• The area with the most severe damage

What is the main cause of earthquakes?

• Hurricanes
• Tsunamis
• Volcanic eruptions
• Plate movement

How do earthquakes impact human lives and structures?

• They cause flooding
• They trigger volcanic eruptions
• They damage buildings and infrastructure
• They create new landforms

What is the main difference between the Richter scale and the Mercalli scale?

• The Richter scale is used for earthquakes on land while the Mercalli scale is used for earthquakes at sea
• The Richter scale assigns a number to an earthquake while the Mercalli scale uses words to describe the earthquake
• The Richter scale is based on survivors' descriptions while the Mercalli scale is more scientific
• The Richter scale measures the amount of earthquake damage while the Mercalli scale measures the strength of the earthquake

Which type of plate boundary is most likely to cause earthquakes?

• Divergent boundary
• Convergent boundary
• Hot spot
• Transform boundary

How do scientists use seismographs to determine an earthquake's epicenter?

• By recording the shaking of Earth's surface
• By comparing multiple seismograms
• By measuring the strength of the earthquake
• By analyzing the type of seismic waves

What is the relationship between plate movement and earthquake occurrence?

• Earthquakes cause plate movement
• Plate movement and earthquakes are unrelated
• Plate movement and earthquakes occur simultaneously
• Plate movement causes earthquakes

What is the role of plate tectonics in causing earthquakes?

• It triggers volcanic eruptions
• It creates pressure along faults
• It causes the Earth's layers to shift
• It creates seismic waves

What is the main cause of tsunamis?

• The pressure building up along a fault
• The occurrence of aftershocks
• The shifting of the seafloor
• The movement of tectonic plates

What is the purpose of the Richter scale?

• To analyze the type of seismic waves
• To predict future earthquakes
• To determine the location of an earthquake
• To measure the strength of an earthquake
