Earthquakes

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological activity such as earthquakes.

Front

Where do most earthquakes occur?

Back

Most earthquakes occur along the borders of tectonic plates.

Front

What is the epicenter of an earthquake?

Back

The epicenter is the point on the Earth's surface directly above where an earthquake originates.

Front

What instrument is used to measure earthquakes?

Back

A seismograph is an instrument that detects and measures the intensity and duration of earthquakes.

Front

How many tectonic plates are there approximately?

Back

There are about 12 major tectonic plates.

Front

How many earthquakes occur each year on average?

Back

Approximately 500,000 earthquakes occur each year.

Front

What is the difference between the focus and the epicenter of an earthquake?

Back

The focus is the point within the Earth where the earthquake originates, while the epicenter is the point directly above it on the surface.

Front

What is a fault line?

Back

A fault line is a fracture or zone of fractures between two blocks of rock, which can lead to earthquakes when stress builds up and is released.

Front

What is the Richter scale?

Back

The Richter scale is a logarithmic scale used to measure the magnitude of earthquakes.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, generated by the sudden release of energy during an earthquake.
