Tracks show a wave form. How to increase the height of the wave form shown??
Just click and drag down on the bottom of the waveform pane.
Or if you just work with a single track all time time either
- View > Track Size > Fit to Height
or for a more permanent solution
- Edit > Preferences > Tracks and check the top item Auto-fit track height to be on

You may be looking for vertical zoom …

Zooming does not change the volume, only the appearance of the waveform.
If you want to increase volume see … Amplify - Audacity Manual
