Answer: -
c. Sediment deposited into water will settle at the bottom in flat layers
Explanation: -
Due to the gravitational force and its activity, layers of sediments is deposited horizontally. Nicholas Steno first proposed this law in 17th century. This is important to understand the plate tectonics. Sediments start depositing parallel to the earth’s surface due to gravity. To analyze the folded and tilted strata, this principle is important. This proves that earth has not been static and various forces have been applied for a longer period of time. The cause of folded strata is due to the movement and collisions of large plates of the Earth’s crust. The surface of sand dunes is however exception to it. On the basis of the above explanation the correct option is Sediment deposited into water will settle at the bottom in flat layers
