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.
The correct answer is - c. east.
The Appalachian Mountains are located in the eastern part of the United States, and since the Rocky Mountains are in the western part of the country, it puts them east of the Rocky Mountains.
The Appalachians are a very old mountain range, they are dated to about 480 million years ago when they formed during the Ordovician Period. At their peak, these mountains reached heights similar to the Rocky Mountains and the Alps in Europe, but because of the natural erosion they have shrunk and nowadays are much smaller in height.
The answer is 4. You round up one number when the decimal point is equal to or more than .5
Answer:
The correct answer is B: The greater the angle of the fault, the greater the compression of the crust.
The most basic features to form in sedimentary basins under extension are normal faults. <em>Normal faults are generally fairly steep</em>, ie <em>have a high dip angle.</em> A fault will form in the crust when the extensional forces acting on it are great enough to cause failure along a fracture plane.
