But on Earth we cand find plasma in lightning, and boreal lights. Each of this have different properties that difference them from the others.  Solid has its molecules very compact, this  makes them have a definite shape, and a definite volume. In solids the particles can't move freely throught the substance they are in. In some solids the shape can be changed, but not in all. And in the ones you can chage it, is difficult to do it. For instance molecules in a liquid aren't so close together, so this  means they adapt to the shape of the container. They don't have a definite shape, so if you put liquid iin a rectangular base, the liquid will absorb the same rectangular shape of its container. Gas is another state of matter, in this case the mole...
