Exploring Earthquakes

The video explores the Earth's structure, focusing on tectonic plates and their movements. It explains how these movements cause earthquakes and other geological phenomena like fault lines, tsunamis, and landslides. The video highlights the destructive potential of earthquakes and the constant changes occurring on Earth. It emphasizes the importance of understanding these processes to stay safe and informed.

What are the large slabs that make up the Earth's crust called?

• Mantle layers

• Continental shelves

• Tectonic plates

• Oceanic ridges

What is a fault line?

• A boundary between the mantle and the crust

• A crack in the Earth's core

• A line where two tectonic plates meet

• A type of earthquake

How do scientists measure the strength of an earthquake?

• By counting the number of aftershocks

• By using the Richter magnitude scale

• By observing the damage caused

• By measuring the depth of the epicenter

What happens when two tectonic plates move away from each other?

• An ocean trench forms

• A valley forms

• A volcano erupts

• A mountain range forms

What natural disaster can be triggered by an underwater earthquake?

• Volcanic eruption

• Tornado

• Hurricane

• Tsunami

What is a landslide?

• A sudden eruption of a volcano

• A large wave caused by an earthquake

• A rapid movement of soil down a slope

• A crack in the Earth's surface

Why do most earthquakes go unnoticed by humans?

• They are too deep underground

• They happen mostly at night

• They occur in remote areas

• They are too weak to be felt
