1. Infer how the height of the lines on a seismograph change with an increase in earthquake magnitude.

his movement is proportional to the intensity of the earthquake,

Explanation:

An earthquake is a record of the intensity of an earthquake as a function of time.

Where the intensity is plotted on the y-axis, which corresponds to the vertical movement of the detector, this movement is proportional to the intensity of the earthquake, therefore the intensity increases the amplitude of the oscillation increases.

And the in x corresponds to time

tube or goog with be a great resource to with that question

not too sure thinking all accelerations are pointed down
