Terremoto

The video explains how energy release within the Earth's crust generates seismic waves, leading to earthquakes, which typically occur at tectonic plate edges. The Richter scale measures earthquake strength, with lower magnitudes being imperceptible and higher ones causing devastation.

What is the primary cause of seismic waves?

• Tidal forces

• Release of energy within the Earth's crust

• Volcanic eruptions

• Atmospheric pressure changes

Where do earthquakes most commonly occur?

• In the middle of tectonic plates

• At the edges of tectonic plates

• In desert regions

• In the ocean

What happens when rocks move over each other at tectonic boundaries?

• They create new landforms

• They release accumulated tension

• They cause volcanic eruptions

• They form mountains

How is the strength of an earthquake measured?

• By the number of aftershocks

• Using the Richter scale

• By the duration of shaking

• By the depth of the epicenter

What is the impact of an earthquake with a magnitude of 7 to 8 on the Richter scale?

• It is harmless

• It is devastating

• It causes minor damage

• It is barely noticeable
