Alarge amount of sediment is deposited on a pkain in a short amount of geologic time. which of the following correctly describes a possible result a- the crust subsides due to the motion of the sediment as it is deposited b-the crust subsides due to the weight of the sediment that accumulates. c- the crust is uplifted due to groundwater infiltrating the sediment d- the crust id uplifted due to the difference in weight between the sediment and the bedrock

The answer is B. The weight of the sediments causes the crust to subside while the crust in the flanks is uplifted in opposite force. It is noteworthy that this is one way how fold mountains are formed. The sediments are squeezed between the uplifting flanking crusts and folds are formed in the sediments.  This phenomenon is common in the seas and oceans where sediments are deposited on the beds by inflowing inland rivers.  

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

chert is a sedimentary rock composed of microcrystalline or cryptocrystalline silica. with this little bit of information, you can come to the conclusion that your answer is c.
