Which of the following statements with reference to Salt Weathering is/are correct?
- 1Salt Crystallisation is the most effective of all the salt weathering processes.
- 2Salt crystal growth is more effective over sedimentary rocks as compared to igneous rocks.
General KnowledgeGeography
- A1 only
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Explanation
Both statements are correct. Salt crystallisation — the growth of salt crystals in rock pores, which exerts pressure as crystals expand — is the most effective salt-weathering process. It acts more effectively on porous sedimentary rocks, whose pores admit saline water, than on dense, non-porous igneous rocks.
