Regarding sedimentary rocks which of the following statements is true?
- AThese are such rocks whose structure depends on temperature and pressure
- BThese rocks are crystalline
- CThese rocks are deposited in layers
- DThese rocks cannot be formed in water
Show answer and explanation
Correct answer: (c) These rocks are deposited in layers
Explanation
Layered or sedimentary rocks are formed when debris obtained from the breaking and weathering of rocks keeps getting deposited in water. Sedimentary rocks are formed not only in water but also by other agents of erosion such as wind, glaciers, etc. They contain adequate amounts of remains of organisms and plant fragments. Sedimentary rocks spread on the Earth’s surface are layered, i.e., they are deposited in strata.
