Which of the following statements with reference to Salt Weathering is/are correct? 1. Salt crystallisation is the most effective of all the salt weathering processes. 2. Salt crystal growth is more effective over sedimentary rocks as compared to igneous rocks.
Both 1 and 2
Explanation: - Statement 1 is correct: Salt crystallisation is a prominent and effective process of salt weathering, especially in arid and semi-arid environments where evaporation leads to crystal growth within rock pores. - Statement 2 is also correct: Sedimentary rocks, being more porous than igneous rocks, are more susceptible to salt crystal growth, which causes disintegration. Hence, both statements are correct. ---
