Answer:
The Colorado stream is extremely helpless by human abuse, natural issues, and destitute stream administration procedure. As a especially over-apportioned water asset, the water quality of the stream is jeopardized by agrarian overdraw, that will increment the saltiness of the stream. to boot, this overdraw is overstated by climactic changeability. With overstated temperature and variable precipitation, the amount of snowmelt contributive to the stream of the stream will exclusively diminish, that subsequently diminishes its capacity capability.

Answer:
<u>Instead of Helium and Hydrogen there are heavier elements in inner planets like Nitrogen and oxygen.</u>
Explanation:
- As the inner planets like Mercury, Venus and Mars and earth have a solid surface which is separated by the Sharpe atmosphere, and their gravity is too low to hold these light gases.
- Uranus is primarily composed of gases and ice of which 83% is hydrogen and 15% helium and rest are trace gases. As in the early composition of the atmosphere, the inner planets like the earth had a solid atmosphere composed of solid silicates elements like magnesium, iron, calcium, and potassium.
- As the earth has a highly unstable atmosphere only carbon, nitrogen and oxygen combined in lightning occur. And planet mercury has no atmosphere thus gravity is too low to hold any gas.
