From the bottom it should be below about 200m but sometimes they are 3km thick, so they can be higher. They can cover the whole sky, they have a dark grey wet look. They usually rain or snow. :D sorry too much information I guess..
nimbostratus
stratus and nimbostratus
nimbstratus is the type of clouds which makes rain. cumulonimbus is the type of clouds which makes hurricane tornados etc.. cumulonimbus stands higher level from nimbostratus.
as altitude inscreases, water vapor level decreases
Fog is usually a very low altitude, probably about ground level.

stratus and nimbostratus
The list of cloud types groups the main genera as high (cirrus, cirro-), middle (alto-), multi-level (nimbostratus, cumulus, cumulonimbus), and low (stratus, strato-) according to the altitude level or levels at which each cloud is normally found.
stratus and nimbostratus
Altitude describes an object's position relative to sea level. An object in a position higher than sea level would have a positive altitude, sea level would have an altitude of zero, and any object below sea level would have a negative altitude.
nimbstratus is the type of clouds which makes rain. cumulonimbus is the type of clouds which makes hurricane tornados etc.. cumulonimbus stands higher level from nimbostratus.
