Commonly the organic solvent is on top, but in the case of DCM in aqueous solution it is on the bottom because it is more dense than water.

The shape of DCM allows it to pack together pretty well, so it can fit more mass in a certain volume. Some liquids just have heavy molecules and so are more dense than water - a very common example is dichloromethane. This is also the reason oil is less dense than water. New comments cannot be posted and votes cannot be cast. Oil molecules are long straight chains that tangle instead of pack, so there's more space between each molecule.
