Because of how dense it is because of all the moisture that it is made up of, which the light is absorbed by, and cannot penetrate as easily as a white cloud (which does not have as much moisture in it).

thank you
by Aditya (aditywantstoparty@Yahoo.co.in) reply please. it will tell me that i am helpfull.
because it is close to rain or a storm.
add. As the cloud gets thicker (taller) the sunlight from above has more and more difficulty in penetrating. Hence the underside of the cloud becomes dark.
Thunderstorms form from very tall cumulonimbus clouds. These clouds can block out a large amount of sunlight. Generally, the tall a thunderstorm, the stronger it is. The most violent thunderstorms have been known to make day as dark as night.
It is sometimes dark because there is a typhoon
or rain will come
Thunderheads appear dark when view from below because they consist of towering cumulonimbus clouds. These clouds are so thick that they block out a substantial amount of sunlight.
When a cloud fills up with too much water, dark clouds form. That's why dark clouds are often a signal that rain is coming.
Because they are tall and contain allot of water vapour which blocks out sunlight.
The clouds of thunderstorms are called cumulonimbus clouds. These cloudse are generally quite tall and so block out a significant amount of sunlight.
BOTH of those kinds of lightning occur.
Such clouds are called cumulonimbus.
Clouds do not make thunder, clouds produce lightning. The lightning heats up the surrounding air causing loud blasts of thunder.

Rain clouds appear dark in color because of their overall density. As water droplets accumulate, their high concentration absorbs light instead of scattering it, resulting in the appearance of dark rain clouds.

Lightning forms in clouds.

No, clouds out of a blue sky would not affect lightning or lack of it
Lightning is caused by a voltage difference between the clouds and Earth, or between clouds.
Lightning is just really large static. Lightning between clouds is called cloud lightning or sheet lightning and is caused when one cloud has an excessive charge and another cloud has an excessive amount of the opposite cloud. The lightning is used to relieve the clouds charge.
When there are dark clouds in the sky, it is a sign that a rain shower is eminent. Clouds full of precipitation are much more dense than other clouds and as a result less sunlight can shine through causing the clouds to appear black.
lightning bolts occur in the clouds.
The lightning happens because of the pressure of the clouds and it the lightning comes out from the clouds naturally.... (lightning are dangerous so don't try to go up and see if it is right or wrong
Tornadoes typically form in the rear half of a supercell. So tornadoes are often preceded by cloudiness rain, thunder, lightning, and sometimes hail. The clouds in a tornadic storm sometimes appear black or greenish.
Cumulonimbus clouds form lightning
