Understanding Earthquakes and Waves Assessment

What is a seismogram?

• A device used to measure the strength of earthquakes

• A paper recording produced by a seismograph

• The point on the Earth's surface directly above the earthquake

• A type of seismic wave

Which type of seismic wave arrives first at a seismograph station?

• Surface wave

• Secondary wave

• Primary wave

• Love wave

What is the epicenter of an earthquake?

• The point inside the Earth where the earthquake starts

• The point on the Earth's surface directly above the earthquake's starting point

• A type of seismic wave

• A device used to record seismic waves

What is lag time in seismology?

• The time it takes for an earthquake to occur

• The time difference between the arrival of primary and secondary waves

• The time it takes for a seismograph to start recording

• The time between two consecutive earthquakes

Which type of plate boundary divides and is associated with the creation of new crust?

• Convergent boundary

• Transform boundary

• Divergent boundary

• Subduction zone

Which seismic wave is typically the most destructive?

• Primary wave

• Secondary wave

• Surface wave

• Body wave

What is a seismograph?

• A scientist who studies earthquakes

• A record of seismic waves

• An instrument that records seismic waves

• A type of seismic wave

What is the hypocenter or focus of an earthquake?

• The point on the Earth's surface directly above the earthquake

• The point inside the Earth where the earthquake starts

• A type of seismic wave

• A device used to record seismic waves

Which type of plate boundary involves plates sliding past each other?

• Convergent boundary

• Transform boundary

• Divergent boundary

• Subduction zone

What is the main difference between primary and secondary waves?

• Primary waves are slower than secondary waves

• Primary waves move faster but with less destruction than secondary waves

• Secondary waves arrive before primary waves

• Secondary waves are less destructive than primary waves
