Understanding Earthquakes: The Role of Tectonic Movements

The video tutorial explains the experience and causes of earthquakes, focusing on tectonic plate movements. It introduces seismology, the study of earthquakes, and the use of seismographs to measure seismic waves. The process of locating an earthquake's epicenter through triangulation is detailed, along with an explanation of the Richter scale for measuring earthquake magnitude. The importance of studying earthquakes for preparedness and safer building designs is emphasized.

What is the primary cause of earthquakes?

• Volcanic eruptions

• Movement along tectonic plates

• Heavy rainfall

• Human activities

What device do seismologists use to measure seismic waves?

• Anemometer

• Seismograph

• Thermometer

• Barometer

How do seismologists determine the epicenter of an earthquake?

• By observing animal behavior

• By using triangulation with multiple seismographs

• By analyzing weather patterns

• By measuring the temperature changes

What does the Richter scale measure?

• The height of mountains

• The magnitude of an earthquake

• The speed of wind

• The depth of the ocean

Why is it important to study earthquakes?

• To predict weather changes

• To enhance communication systems

• To improve agricultural practices

• To prepare for emergencies and build safer structures
