Q: Soils, in which rate of rock decomposition is greater than the rate of erosion or transportation, is best known as:
  • A. alluvial soil
  • B. lacustrine soil
  • C. transported soil
  • D. residual soil
Correct Answer: Option D - Residual soils– When rock weathering process is faster than the transportation process. • Retains many of the characteristics of the parent rock. Transported soil– • Transported soils are classified based on the mode of transportation and the final deposition environment. (a) Soils that are carried and deposited by rivers are called alluvial deposits. (b) Soils that are deposited by flowing water or surface runoff while entering a lake are called lacustrine deposits.
