Understanding Earthquakes

What causes earthquakes?

• Movement of water

• Solar flares

• Release of energy

• Wind pressure

What are tectonic plates?

• Large bodies of water

• Pieces of the Earth's crust

• Types of seismic waves

• Layers of the atmosphere

What is the hypocenter of an earthquake?

• The location where the earthquake starts

• The center of the Earth

• The area of maximum damage

• The point on the Earth's surface

What is the Richter scale used for?

• Calculating water pressure

• Determining wind speed

• Scaling earthquake magnitude

• Measuring temperature

What are seismic waves?

• Waves in the ocean

• Sound waves from earthquakes

• Waves created by tectonic plate movement

• Light waves during an earthquake

What is the most powerful earthquake recorded?

• Magnitude 6.0

• Magnitude 7.5

• Magnitude 9.5

• Magnitude 8.0

What are body waves?

• Waves that travel through the Earth's surface

• Waves that move through the Earth's interior

• Waves that are felt by humans

• Waves that cause tsunamis

What are surface waves?

• Waves that are felt only underground

• Waves that are generated by wind

• Waves that cause the most destruction

• Waves that travel through water

What is the temperature range of the Earth's core?

• 6000 to 7000 degrees Celsius

• 1000 to 2000 degrees Celsius

• 3000 to 4000 degrees Celsius

• 4500 to 5500 degrees Celsius

What happens to buildings during a magnitude 6.0 earthquake?

• They collapse completely

• They may have cracks

• They remain unaffected

• They become stronger
