Pretty sure it's outer core, lower mantle because the inner core is solid iron
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.
Ehhh, personal opinion. There was a point in time I wanted money than anything else in the world. My question to you is why can't we have both? (';
Answer:
B. elderly people
Explanation:
I don't know if this counts but personally growing up in an Asian community, I think it's safe to say we pretty much worship our elders and if we didn't we'd be in big trouble.
So why is it B.?
Respecting the elderly is an ancient Asian tradition, and is also a part of daily life in terms of respect. B. falls into both categories.
Why is it not the others?
Japanese have just incorporated urban life and trendy fashion into their life and not any sooner than this generation so not A.
Outsiders is not very relevant to the answer because if you're an outsider, so be it so I wouldn't say C.
Asians think more for family than theirselves which is why it wouldn't be D.
