Which of these are the two major sources of nitrate pollution in rivers? the burning of fossil fuels by factories and cars anima

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.
Lystrosaurus is a species found in a warmer continent. if the fossil was found in Antarctica it shows before continental drift that Antarctica was a warmer climate and that it was located closer to warmer continents.
As the sedimentary and igneous and metamorphic rocks are distinct from each other as they appear on the landscape but show similar internal properties and thus allowing us to recognize them from a distance.
<u>Sedimentary Rocks range from shake sandstone to limestone and conglomerate. While Metamorphic i.e foliated being Slate, Phyllite, Schist, and Gneiss, etc. While the Nonfoliated Metamorphic rocks are Quartzite and Marble</u>.
Rocks revolve in there set rock cycle forming distinctive and newer rocks over the geologic time scale of earth. As each rock type is altered with force to produce the fro example a basalt rock when subducted and could be merged with the mantel to form in the water cycle.
As these are called secondary changes in the evolutionary phases of rocks which then can<u> transition into metamorphic rocks through the process of mountain building in the orographic belt</u>s.
As a result, other rocks are recrystallized to form a sedimentary rock in its next phase which is unstable and subject to weathering. Transitions deeply impact the chemical and physical properties of rocks.
