Severe turbulence in level flight does not impart sufficient forces upon modern aircraft to cause a crash. It nevertheless imposes a risk of injury to the passengers and crew. There have been hundreds of documented cases during severe turbulence in which unrestrained passengers and crew (without their seatbelts fastened) were "thrown" about the cabin leading to serious injury and death (1).
There is a special form of turbulence, called windshear (also known as wind shear), which presents a potentially high risk to the aircraft itself, and a particular form of windshear, called a microburst, which has proven catastrophic to aircraft during final approach for landing. Microbursts are especially vexing because they are extremely powerful, localized, and they manifest themselves quickly and without warning. For example, Delta Airlines flight 191, a Lockheed L1011 that crashed at Dallas-Forth Worth, Texas, USA on 2 August 1985, encountered a microburst near the end of the runway less that two minutes after an earlier aircraft landed safely on the same runway without experiencing the microburst. (2).
Microbursts are such a serious concern that modern airports and airplanes are equipped with windshear detection and alert systems that advise air traffic controllers and pilots of potential windshear conditions.

Yes clouds can cause turbulence because when an air craft controller flies an airplane into a cloud it can cause the plane to shake and/or bounce, etc.
Cumulonimbus
Towering cumulus clouds.
Lightning is caused by a voltage difference between the clouds and Earth, or between clouds.
No. It is the buildup of static electricity in the clouds, caused by the motion of the air within the clouds.
In a high pressure system air sinks and is compressed. As the air is compressed it heats up, which can cause clouds to evaporate.
Cumulonimbus
Clouds with considerable vertical development and associated turbulence.
Towering cumulus clouds.
Turbulence.
Yes. This is part of what is called wake turbulence.
Turbulence.
In the ionosphere THERE ARE NO CLOUDS (no water clouds but plasma clouds)
No.Tornadoes form within the updraft portion of a thunderstorm, near a downdraft. This will cause quite a bit of turbulence.
topography of earths surface changes because of the turbulence of water.In which this turbulence causes the formation of a new topographic sketch in earths surface.
It might shake only when passing through turbulence. Clouds may or may not be turbulent. Pilots learn which are and which are not turbulent. Clouds that occur in even layers are very smooth. Thunderheads and lenticulars are often violent and are usually best avoided.
Stratus clouds.
Along with friction, turbulence slows down the waters flow and also may erode the stream bed
