1. Sedimentary rocks are formed at the earth's surface by the hydrological system
2. The formation of sedimentary rocks involves the weathering of preexisting rocks
3. Sedimentary rocks contain fossils
4. Sedimentary rocks typically occur in layers
Which of these statements are correct?
Correct Answer: (d) 1, 2, 3 and 4
Solution:Sedimentary rocks are formed by the accumulation of sediments. This sediment or debris accumulates in low lying areas like-lakes.
