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
What did the drowned forests in cascadia show scientists about the size of past earthquakes in the region?
The drowned forests in Cascadia provided crucial evidence about the magnitude of past earthquakes through the study of tree rings and sediment layers. When massive subduction zone earthquakes occur, they can cause land subsidence, leading to the inundation of coastal forests. By dating the layers of sediment and the growth patterns of the trees, scientists have been able to reconstruct a timeline of significant seismic events, revealing that some past earthquakes reached magnitudes of 9.0 or greater. This research underscores the potential for future large-scale earthquakes in the region.
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.
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

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.
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

Is there going to be an earthquake on the 20th in christchurch?
Nobody can know that for sure. Earthquakes are unpredictable and scientists have not been able to predict them at this time.
Why do scientists compare earthquakes to rubber bands?
comparing rubber bands to earthquakes is not common almost all scientists do not compare those two.
