By looking at the rocks and the way the layers of rock are stacked scientist feel they have pretty good idea of the time and severity of many past earthquakes.

Why are map showing locations of past earthquakes useful to scientists?
Earthquakes happen when the Earth's crust shifts violently. So if we know that an earthquake has happened in California, then scientist know that the crust under California is unstable, therefore making earthquakes more likely to happen there. Earthquakes can happen anywhere, but the tend to happen repeatedly in certain spots
Who are seismologests?
scientists who study earthquakes
What is the study of earthquakes and what is the instrument used by scientists to record earthquakes data?
Seismograph.
What do scientists use to locate hidden faults?
Earthquakes
Why is it important for scientists to know the speed of plate tectonics?
It is important so that they can possibly predict future earth movements as to when and where it will happen. Ex: earthquakes

How do you know about the ancient past?
We know about the ancient past because of scientists
How do scientists know about the structure of the earth's interior?
Because of the study of seismic waves from earthquakes
How do we know about the past?

What do scientists use to measure earthquakes?
Scientists use seismographs.
How do earthquakes allow scientists study earth's interior?
The seismic waves that the earthquakes make travel slowly and scientists can track them
Can humans predic earthquakes?
Yes they can but only a couple of minutes before it strikes. Scientists know where earthquakes could occur but the when is unknown until a few minutes beforehand.
Who are seismologests?
scientists who study earthquakes
What do scientists not know about earth?
They do Not know how to predict when and where Earthquakes will occur in adequate time to give people enough warning in order to save lives.
What is the study of earthquakes and what is the instrument used by scientists to record earthquakes data?
Seismograph.
Why do scientists compare earthquakes to rubber bands?
comparing rubber bands to earthquakes is not common almost all scientists do not compare those two.
