How do seismograms recorded during earthquakes help scientists learn about the composition on earth?
Seismograms give information about the path of seismic waves and the speed of seismic waves. The speed of seismic waves depends on the density of the material the seismic wave is traveling in. We know, for example, that the core of Earth is liquid, because S waves do not travel through the center of Earth.

How are earthquakers used to explore the inner structure of the Earth?
Earthquakes create seismic waves that travel through the Earth. By studying how these seismic waves travel and are recorded on seismographs, scientists can infer information about the Earth's internal structure, such as the composition of different layers and the presence of boundaries between them. By analyzing the behavior of seismic waves during earthquakes, scientists can map out the Earth's interior and learn more about its composition and properties.
Where did scientists record earthquakes as early as 780 bce?
Scientists recorded earthquakes as early as 780 BCE in ancient China, during the Zhou Dynasty. These early recordings were made by a device called a seismoscope created by the Chinese philosopher and scientist Zhang Heng.

With which device are earthquakes recorded?
Earthquakes are recorded using seismometers, which are highly sensitive instruments that detect and measure the vibrations in the Earth's crust caused by seismic waves emitted during an earthquake. These devices help scientists monitor and study earthquakes to better understand their causes and potential impacts.

Has California had any hurricanes or earthquakes?
California has had many earthquakes, but no recorded hurricanes.
What tracks earthquakes and volcanoes?
Seismology: the study of the vibrations from earthquakes, recorded on seismographs.
How many earthquakes were recorded in 1956?

What does the height of the jagged lines on a seismogram indicate?
The height of the jagged lines on a seismogram indicates the amplitude or size of the seismic waves recorded by the seismograph. Larger amplitudes represent stronger ground motion caused by seismic events, such as earthquakes.
Where is the most recorded number of earthquakes?
