Answer:
This is the best explanation for why there is such a small amount of phosphorus that moves into aquatic systems:
1. Phosphorus is highly stable in the atmosphere and remains there for long periods of time.
Explanation:
The phosphorus first cycle is the process by which the phosphate ion passes in very small amounts through the lithosphere from volcanic aeorosols, then to the hydrosphere, where it stays from 20,000 to 100,000 years in the ocean, and finally to biospherere, where rain and erosion helps washing the phosphorus from the rocks into the soil. So, raining is the beginning of the phosphorus´s second cycle, so it is also, the slowest one of the matter cycles that is why the natural total background phosphate levels in several bodies of freshwater range from 0.005 to 0.05 mg/L. Phosphorus remains mostly on land and in rock and soil minerals.
Although abundant on our planet´s sedimentary rock crust and in human body, phosphorus to commercialize is only found in minerals therefore, phosphates mining activity and calcium heating is the only way to get it in its pure elemental form. It is an essential nutrient for plants and animals and a big percentage of the mined phosphorus is used to make fertilizers.
Answer: False
Explanation: Because there is no way erosion is a major problem along coastlines in every continent.
Volcanic eruptions are formed when so much PRESSURE from the magma inside the volcano builds up to it's boiling point.
An example would be like shaking soda as soon as the pressure is released there is foam. It's then same concept but with magma aka lava
Hope this helped
Answer:
The 50º West meridian is an imaginary line that crosses from the north pole to the south pole, passing through the center of Greenland and Brazil. Both nations, in the part of the territory that this imaginary line crosses, have a time zone of -3 UTC.
In turn, the 45º East meridian also goes from the north pole to the south pole, but this passes through the eastern part of the European continent, the Caucasus, the Arabian Peninsula and the Somali Peninsula, as well as through the center of Madagascar, regions that have a time zone of +3 UTC.
Therefore, if it were 12 noon at the 50º West meridian, it would be 6 PM at the 45º East meridian.
