What do scientists hope to learn by collecting information about friction along faults?

By measuring friction along faults, scientists can tell where rocks are moving along easily and where they are locked. They hope to use this information to predict where major earthquakes might occur.

This is from my notes from school

By measuring friction along faults, scientists can tell where rocks are moving along easily and where they are locked

Knowing this information would make scientists able to Predict when earthquakes will happen within a certain area. If the rocks are moving along easily, earthquakes would most likely not happen. If they are locked, the chance of earthquake from occurring its pretty high.

Step-by-step explanation:

A positive parabola is one that has a + sign out front or no sign at all (and the positive is understood).  A positive parabola opens like a cup with a bottom.  Therefore, the positive parabola has a min value.  A negative parabola opens upside down, like a mountain with a peak.  Therefore, the negative parabola has a max value.
