Answer:
b Freezing temperatures change the quantity of ocean water, and rock made of larger grains forms the top layer.
Explanation:
Review the diagram, which shows a sedimentary sequence.
What could cause a sea-level change that would result in this sedimentary sequence?
a Melting ice caps change the quantity of ocean water, and rock made of calcium carbonate forms the top layer.
b Freezing temperatures change the quantity of ocean water, and rock made of larger grains forms the top layer.
c Rising temperatures change the density of ocean water, and rock formed in still waters appears in the upper layer.
d Tectonic activity changes the shape of the ocean basin, and rock formed in the deep sea appears in the upper layer.
