​

Answer 1

Answer:

There are several systems of soil classification which are based generally on particle size or on some additional soil properties such as plasticity and compressibility. Soil classification based on particle-size characteristics is widely used, especially for preliminary or general descriptions (see Section 6.4). However, any system based on particle size alone is likely to be misleading because the physical properties of the finest soil fractions depend on many factors other than particle size. This has led to the development of the Unified Soil Classification (USC) which is considered today to be the most useful of the engineering soil classification systems. The USC permits reliable classification on the basis of relatively few and inexpensive laboratory tests.
