The Science Behind Earthquakes and Tectonic Plate Movements

The video explains earthquakes, their causes, and effects. It covers Earth's structure, tectonic plates, and how their movements lead to earthquakes. The Ring of Fire is highlighted as a major earthquake zone. The video also describes how earthquakes are measured using seismographs and provides a hands-on activity to create a seismograph model.

What are the four major layers of the Earth?

• Crust, Mantle, Outer Core, Inner Core

• Crust, Mantle, Lithosphere, Inner Core

• Crust, Mantle, Outer Core, Lithosphere

• Crust, Lithosphere, Outer Core, Inner Core

What are tectonic plates?

• Types of volcanic eruptions

• Layers of the atmosphere

• Massive pieces of rock that make up the Earth's crust

• Large bodies of water

Which type of plate movement involves one plate sliding under another?

• Lateral sliding

• Spreading

• Subduction

• Convection

Where do nearly 90% of all earthquakes occur?

• Atlantic Ocean

• Indian Ocean

• Ring of Fire in the Pacific Ocean

• Arctic Ocean

What is the epicenter of an earthquake?

• The point where tectonic plates meet

• The area with the most damage

• The location on the Earth's surface directly above where the earthquake starts

• The point where the earthquake starts underground

What natural disasters can earthquakes trigger?

• Hurricanes and tornadoes

• Wildfires and heatwaves

• Avalanches, landslides, and tsunamis

• Floods and droughts

What is the significance of the Ring of Fire?

• It is a region with frequent earthquakes and many active volcanoes

• It is a region with no volcanic activity

• It is a region with the highest mountains

• It is a region with the largest deserts

What device is used to measure the intensity of an earthquake?

• Seismograph

• Anemometer

• Thermometer

• Barometer

What is considered a major earthquake in terms of magnitude?

• Above 6.0

• Above 8.0

• Above 7.0

• Above 5.0

What is the purpose of the DIY seismograph activity?

• To understand how a seismograph records earthquake movements

• To measure the intensity of sound waves

• To simulate the movement of tectonic plates

• To create a model of a volcano
