False-col SEM of collection of ice crystals
Numéro d’image : 11737115
| False-colour scanning electron micrograph of a collection of ice crystals. Snow & ice crystals have a characteristic hexagonal symmetry. Each crystal is made up from water molecules,arranged with 2 hydrogen atoms making an angle of 105 degrees with 1 oxygen atom. The fixed shape of the water molecule means they can assume a stable crystal arrangement only when arranged as a 6- branched figure. Despite essential hexagonal similarity no two crystals are identical because their growth is influenced by temperature,humidity,air currents etc.,& these conditions are never quite the same.
