Carbon in the ocean originates from the atmosphere. This statement is True. In fact, there exists Oceanic carbon cycle. Carbon dioxide is absorbed by the ocean's surface from the atmosphere. It is then converted into a dissolved inorganic carbon. Then it is followed by series of steps following the oceanic carbon cycle.
The correct answer is letter D. Oceanic-Continental. The answer is oceanic-continental because of the transform. The transform itself is a boundary is essentially a horizontal movement of plates relative to each other. ON the other hand a Convergent is where plates converge.
Answer:
animal wastes and fertilizers
Explanation:
The majority of the nitrates that are polluting the rivers come from the animal wastes and from the fertilizers used in the agriculture. The increased amounts of nitrates in the rivers causes eutrophication. This basically means that the water is becoming over-saturated with nutrients. This leads to the spreading out of the algae. As the algae spread out more and more, they cover the surface part of the water, so large portions of the rivers do not receive sunlight, which kills of the organisms that use photosynthesis. Further, the algae reduce the amount of oxygen in the water, often resulting in dying out of the fishes. It is a chain reaction that leads from one thing to another and the end result is devastating.
