D. because the size and shape of the slope determines weather the load can be sustained and c is correct too because the shape affects how much you can load and b. is correct as also because if the volume is very large it can affect the rivers load and flow.
A river load can be define as the debris or sediments carried away by the stream of river water. The materials which are translocated includes the rocks, stones and other large particles. Generally, the finer particles floats over the water surface. River slope, shape of the stream bed and volume of flow of water all are the factors which can affect the river load.
River slope will cause the erosion of surface materials by using water. Shape of the stream bed is also a factor this is because of the fact that the wider the surface covered by water more erosion can be caused. If the volume of water flowing in the stream is high the water will take away the particles by causing friction over the surface.
The answer to your question is A. Wrought iron because amongst its other properties, wrought iron becomes soft at red heat, and can be easily be forged and forge welded.
If you are taking about George Washington and George Washington Carver then the difference is one was a president and army leader (George Washington) while the other George Washington Carver was an inventor and botanist that is very well known for his inventions with peanuts. If not one is spelled with an r (George) and the other without (Geoge).
