What are different class of crystals?
Minerals crystals are divided into six systems depending on the relationships of length of axes and angles between axes. The six mineral crystal systems are: cubic, hexagonal, trigonal, tetragonal, orthorhombic, triclinic, and monoclinic.
How many types of crystals present?
The problem is that "types" is not a well-defined word in the contest of this problem. Do you mean morphology, lattice system, space group, or what? There are more or less infinitely many possible morphologies (I'm pretty sure, though I wouldn't necessarily want to try to prove it, that it's a countable infinity). There are 7 lattice systems: triclinic, monoclinic, orthorhombic, rhombohedral, tetragonal, hexagonal, and cubic. There are 230 distinct space groups, and no I'm not going to list them. Get a graduate-level chemistry book on X-ray crystallography if you really want the details.

What is the difference between a tetragonal crystal and a cubic crystal?
what is the difference between an cubic and a tetragonal crystal
Seven types of crystal?
# Cubic or Isometric - not always cube shaped! You'll also find octahedrons (eight faces) and dodecahedrons (10 faces). # Tetragonal - similar to cubic crystals, but longer along one axis than the other, forming double pyramids and prisms. # Orthorhombic - like tetragonal crystals except not square in cross section (when viewing the crystal on end), forming rhombic prisms or dipyramids (two pyramids stuck together). # Hexagonal - six-sided prisms. When you look at the crystal on-end, the cross section is a hexagon. # Trigonal - possess a single 3-fold axis of rotation instead of the 6-fold axis of the hexagonal division. # Triclinic - usually not symmetrical from one side to the other, which can lead to some fairly strange shapes. # Monoclinic - like skewed tetragonal crystals, often forming prisms and double pyramids.
What is a Orthorhombic?
In crystallography, the orthorhombic crystal system is one of the seven lattice point groups. Orthorhombic lattices result from stretching a cubic lattice along two of its orthogonal pairs by two different factors, resulting in a rectangular prism with a rectangular base (a by b) and height (c), such that a, b, and c are distinct. All three bases intersect at 90° angles. The three lattice vectors remain mutually orthogonal. There are four orthorhombic Bravais lattices: simple orthorhombic, base-centered orthorhombic, body-centered orthorhombic, and face-centered orthorhombic.
What is the difference between different kinds of crystals?
In short, crystals differ by their chemistry and/or symmetry. Crystals are solids whose atoms are arranged in a repeating pattern. Table salt, NaCl, is a common example. Ions of sodium and chlorine are arranged in a regular three-dimensional grid. The symmetry of table salt can be generalized as cubic. Quartz, SiO2, is another common example. Quartz is composed of SiO4 tetrahedra that also follow a repeating pattern. However, instead of cubic, quartz is either in the trigonal or hexagonal system. This is evident in nicely formed quartz crystals, which tend to have six prism faces. To compare, quartz and salt have chemical differences (SiO2 versus NaCl) and symmetry differences (trigonal/hexagonal versus cubic), making them two different crystals (I prefer to say two different minerals). Two crystals can be different and still have the same chemistry, though. For instance, olivine and ringwoodite are both (Fe,Mg)2SiO4. But olivine is orthorhombic, and ringwoodite is cubic.
How many different systems are crystals classified into?
Seven. They are: Cubic - all angles 90 degrees, all sides equal length Trigonal - all angles 90 degrees, two sides equal and the third unequal Orthorhombic - all angles 90 degrees, no sides equal Hexagonal - two angles 90 degrees and one angle 120 degrees, two sides unequal and the third unequal Trigonal - all angles equal but not 90, all sides equal Monoclinic - two angles 90, one more than 90, and no sides equal Triclinic - no angles equal, no sides equal For a graphical representation of these, see http://en.wikipedia.org/wiki/Crystal_system#Classification_of_lattices
Cubic Tetragonal Monoclinic and Hexagonal are words used to describe a mineral's?

What is crystal systems?
It is a system of classification of crystals into 7 crystal systems(Cubic,Tetragonal,Othorgonal,Hexagonal,Trigonal.Monoclinic and Triclinic) on the basis of their Geometrical properties and symmetry (Diads,Triads,Tetrads,Planes of symmetry,Centre of symmetry)
