Answer:
D. Many, many years of deposition
Explanation:
The layers of the rocks in one region of the parks are smooth and distinct, which are evidence of many, many years of deposition.
The layers on the rocks are because of different deposition of sediments. Different sediments deposited over the rocks through wind, water and ice over the ages.
Hence, the correct answer is D.
A is correct. water is incompressible, so it will always have the same density, regardless of volume
a)
OCH₃⁻ + H₂O → CH₃OH <em>(methanol) </em>+ OH⁻ <em>(hydroxide)</em>
here, the methoxide ion acted as a base, by bonding with the hydrogen atom released by water to form methanol and hydronium ion
b)
ClO⁻ + H₂O → HClO + OH⁻ <em>(hydroxide)</em>
The Hypochlorite ion bonded with the proton released by water, to form Hypochlorous acid and hydronium ion
