To make it white.-No. Dust or cloud nuclei is needed to form a cloud because the water particles need something to stick to. When a bunch of these water droplets stick together and form one, it becomes a cloud.
A sand tornado is not a true tornado but a phenomenon called a dust devil. A dust devil takes for form of a whirling cloud of dust as dust is sucked up by the vortex. It may appear tubelike and gradually fades into nothing farther up.
Precipitation doesn't fall from every cloud because not all clouds are large enough to release a form of precipitation yet.
No. Hurricanes are massive storm systems that require large amounts of moisture to form. If there is not enough moisture for clouds to form there can't possibly be a hurricane. Tornadoes form from thunderstorms and by definition must be in contact with both the cloud base and the ground. There is a different sort of phenomenon, however, called a dust devil. These are whirlwinds that often form on clear, sunny days. They are not tornadoes, but they look like them. Dust devils are much weaker than tornadoes and are usually harmless.
A mass of tiny drops of water in the sky is called a cloud. These clouds become heavy and then create rain.
a protostar
A nebula
A gas cloud. It must contain dust to form planets. (And lots of hydrogen to form a star.)
They form themselves.
Nebula
This is referred to as the debris cloud.
Cloud condensation nuclei are solid particles around which cloud droplets form. Dust and salt are examples of particles that can become cloud condensation nuclei.
Theory that states dust and clouds condensed to form the sun and the planets by gravitational means
Gas
It is called nebula
dust and other particles
cosmic dust
