<u>There are a total six crystal system like triclinic, monoclinic, tetragonal, hexagonal, orthorhombic and cubic</u>.
Explanation:
The crystal forms of the crystal family refer to several classes of crystals that are informally formed by the grouping of crystal and being divided based on sources.
The crystal; system that corresponds to space groups is given a lattice system giving them a 32 point scale.
These points are assigned to the trigonal crystal system which consists of all the above 6 system forms of crystals.
Their name is given by Whittaker who formed these crystal structures as protein structures
The earth rotates on the axis that passes through the north and the south of the planet and is of 24-hour duration. Similar to that of the rotation of the moon which is sideral, this rotation is in the anticlockwise direction. And this originated by the angular movement of the clouds of the dust and gases that have coalesced to for the solar system.
