Crystals have an orderly arrangement of their constituent particles. In comparison, amorphous solids have no such arrangement. Their particles are randomly organised.
Crystals have a specific geometric shape with definite edges. Amorphous solids have no geometry in their shapes
Crystalline solids have a sharp melting point on which they will definitely melt. An amorphous solid will have a range of temperature over which it will melt, but no definite temperature as such
Crystals have a long order arrangement of their particles. This means the particles will show the same arrangement indefinitely. Amorphous solids have a short order arrangement. Their particles show a lot of variety in their arrangement.
Crystalline solids cleavage (break) along particular points and directions. Amorphous solids cleavage into uneven parts with ragged edges.

Amorphous solids, such as glass, are those solids that do not have any underlining order in their molecular structure. On the other hand, crystalline solids are those solids that have a well defined order in their structure.
