So, scientists have to x-ray the earth to be able to determine the vibrations of the earths to see the activity level of the crusts. "Seismologists can determine what lies beneath Earth’s surface based on the time it takes for those seismic waves to reach seismometers in other parts of the world and changes to the wave amplitude that occur as the waves travel." this sentence from the passage describes what these seiesmologists do and how and why they work.]]> 2020-02-20 14:21:18 UTC https://padlet.com/video6292/atadrccxi3q4/wish/448028443 https://padlet.com/video6292/atadrccxi3q4/wish/448028447 The deepest man made hole is 12.3 kilometers, barely 1% of the way to the Earth's surface.

Some of these seismic vibrations are so powerful that they can almost take pictures on what the crust looks like at the moment. The main reason they want to look inside is to look for faults in the crust. Most faults are at locations of many earthquakes, such as California, and The Ring of Fire. ]]> 2020-02-20 14:23:43 UTC https://padlet.com/video6292/atadrccxi3q4/wish/448030444 https://padlet.com/video6292/atadrccxi3q4/wish/448030933 seismologists have to use vibrations to basically x-ray the earth. so they built over 2,000 seismic stations as part of transportable array experiment.which is a government funded experiment where hired men placed the stations on land owned by people who agreed with the project.]]> 2020-02-20 14:24:11 UTC https://padlet.com/video6292/atadrccxi3q4/wish/448030933 https://padlet.com/video6292/atadrccxi3q4/wish/448030959 in order to study the earths interior seismologists use vibrations at the earths crust ]]> 2020-02-20 14:24:11 UTC https://padlet.com/video6292/atadrccxi3q4/wish/448030959 https://padlet.com/video6292/atadrccxi3q4/wish/448030989 Scientists measure and map vibrations to know what is inside the Earth's interior.

Well, scientists can use Seismic Vibrations to find more about the inside of the earth. These studies range from Material, to Density, Temperature, Shape, and more. You're able to see a "picture" of Earth's interior by placing Seismographs across a Country or Continent. These Seismographs then connect the information collected during Seismic Activity, like Tectonic Plate Movement. We have to use this method, as digging father down, the Pressure and Heat start to get too extreme to work in. The deepest hole we've managed to achieve is around 12.3 Kilometers down.]]> 2020-02-20 14:43:38 UTC https://padlet.com/video6292/atadrccxi3q4/wish/448047461 https://padlet.com/video6292/atadrccxi3q4/wish/448047579 It is, so far, impossible to drill into Earth's core, and instead seismologists have used vibrations to monitor below earth’s surface. Using vibrations acts as a x-ray that doctors use to examine the inside of the body. By mapping the vibrations seismologists can figure of structure, rocks, and temperatures. ]]> 2020-02-20 14:43:47 UTC https://padlet.com/video6292/atadrccxi3q4/wish/448047579
