What are the differences between transverse and longitudinal waves?

The differences between transverse and longitudinal waves are as listed below:

Transverse waves
Longitudinal waves
The particles of the medium vibrate in the direction perpendicular to

the direction of wave propagation.

The particles of the medium vibrate parallel to the direction of wave propagation.
Alternate crests and trough are formed.
Alternate compression and rarefaction of the medium are formed.
These are formed in solids and over liquid surfaces.
These are formed in solids, liquids and gases.
These waves produce the variations in the density of medium.
These waves do not produce variations in the density of the medium.
Transverse waves can be polarized.
Longitudinal waves cannot be polarized.
