There was no gravity to pull the small water droplets down before they coalesced. The stronger the attractive forces the higher the surface tension. Translational motion is restricted. Larger attractive forces than in the liquids. They have a well-defined network called a crystal lattice.
Examples are metals, diamond, salts.
Amorphous solids have a random distribution of particles. Examples are supercooled liquids called glasses, which contain a great deal of disorder. Metallic solids are held together by metallic bonding. The simplest way of looking at it is that you have positive nuclei surrounded by a sea of electrons. A pure metal crystal represents one of the simplest crystal system.
