Earthquake Test 2

Front

What method do seismologists use in locating an epicenter?

Back

Triangulation is the method used by seismologists to locate the epicenter of an earthquake by measuring the time it takes for seismic waves to reach different locations.

Front

Where do earthquakes most often occur?

Back

Earthquakes most often occur near plate boundaries, where tectonic plates interact.

Front

What does the letter 'a' represent in seismic wave terminology?

Back

The letter 'a' represents amplitude, which is the height of the wave and indicates the energy of the earthquake.

Front

How much bigger is a magnitude 4 earthquake compared to a magnitude 6 earthquake on the Richter Scale?

Back

A magnitude 4 earthquake is 100 times bigger than a magnitude 6 earthquake on the Richter Scale.

Front

What type of rating does the Richter Scale provide?

Back

The Richter Scale provides a rating of the magnitude of an earthquake based on the amplitude of seismic waves.

Front

What is the definition of an epicenter?

Back

The epicenter is the point on the Earth's surface directly above the focus of an earthquake.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact, causing earthquakes.

Front

What is the focus of an earthquake?

Back

The focus is the point within the Earth where an earthquake originates.

Front

What is the difference between the Richter Scale and the Mercalli Scale?

Back

The Richter Scale measures the magnitude of an earthquake, while the Mercalli Scale measures the intensity and effects of an earthquake.

Front

What is a seismic wave?

Back

A seismic wave is an energy wave that travels through the Earth, generated by an earthquake.
