The first task in interpretation of seismic data
is to figure out the approximate numerical value
of the **vertical exaggeration**.
The vertical exaggeration is 2/*v* because it is the ratio of
the apparant slope
to the actual slope
where .Since
the velocity generally
*increases* with depth,
the **vertical exaggeration** generally
*decreases* with depth.

For velocity-stratified media, the time-to-depth conversion formula is
