Explain MIT system of classification of soils.

The MIT system of classification of Soils was developed by Professor G.Gilboy at Massachusetts Institute of Technology in USA. In this system, the soil is divided into four group as shown below:

1. Gravel: particle size greater than 2 mm.
2. Sand: particle size between 0.06 mm to 2 0 mm.
3. Silt size: particle size between 0.002 mm to 0.06 mm.
4. Clay size: particles size smaller than 0.002 mm.
