A seismograph operates on the movement of the ground during an earthquake. It is sensitive enough to record the movement of a truck nearby.
A seismometer is an instrument that is anchored to the ground and records the Earth's movements, specifically seismic waves caused by earthquakes and other sources of ground motion.
The seismograph was invented by the Chinese polymath Zhang Heng in 132 AD during the Han dynasty. Zhang's seismoscope was able to detect and indicate the direction of earthquakes from hundreds of miles away.
A seismogram is a record of ground motion produced by seismic waves from an earthquake or another source. It typically shows the amplitude and frequency of the seismic waves over time, helping seismologists analyze and understand the earthquake's characteristics.
A seismograph is used to measure and record the vibrations caused by earthquakes or other seismic activities. It helps scientists monitor and study the intensity, duration, and frequency of seismic waves generated by these events.
Earthquake patterns, including their depth and distribution, can provide evidence of sea floor spreading by showing a concentration of earthquakes along mid-ocean ridges where new oceanic crust is being formed. As tectonic plates diverge and new crust is created, stress builds up and is released through earthquakes. The pattern of earthquakes along mid-ocean ridges provides a visual representation of the tectonic activity associated with sea floor spreading.
Geologists use seismographs. They try to see when an earthquake is going to occur.
the seismograph was invented in Chicago, 1800.
It's a seismograph.
A seismogram is a record of an earthquake that's obtained from a seismic instrument. It's in the form of a graph.
Why, a seismographer of course! Seriously though... Anyone who studies, or monitors for, earthquakes, volcanoes, & other such phenomena would use one.
The correct spelling (transposed) is seismograph(measures and records seismic activity).
That would be a secondary, or 'S' wave. Moving in a snakelike movement, this wave has to travel a farther distance, so it takes longer to reach the recording equipment.
a siesmic wave is a wave that travels through the earth. there are two MAIN types, P and S waves. a siesmograph shows the type of wave and how far away it is from that point.

They got their education by secretly learning it if their master didn't allowed because it was illegal. Sometimes, their masters tought the slave even though it was against the law. By secretly learning it, they could learn it off another slave or steal a book and educate themselves.
