The theory of plate tectonics evolved from the previous theory of continental drift. Alfred Wegener came up with the latter theory in comparing the coastline shapes of for example eastern South America with western Africa they seemed to fit together. However, there was no mechanism for this until I believe in the late 1960's or early 1970's the theory of plate tectonics was developed which the Canadian geophysicist played a part in J. Tuzo Wilson. The latter theory shows how the mid-oceanic ridges are spreading and the continental margins have the ocean floor subducting.

Which of these is a disadvantage of hydropower?
kotegsom [21]

Answer:

C. It harms aquatic organisms

Explanation:

The hydropower is a one of the most commonly used in the world. It is based on the power of the water, and by building a dam on a river, the water is accumulated, and its power used for production of electrical energy. While this type of power has lot of advantages, like having long lifespan, being eco-friendly, and it has high efficiency, it also has some negatives about it. The biggest negative by the hydropower is that it causes harm tot he aquatic organisms. Because there is a dam built, the water becomes more stagnant, meaning that it becomes warmer, harming the organisms that are not able to adapt to it. The dam restricts the migration of the aquatic organisms, which is especially a big problem for the ones that migrate because of mating. The nutrients start to concentrate in front of the dam, while after the dam they are in very low quantity.
