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.

A canyon is a natural area where both living and non-living organisms are found. Residing near it brings several benefits. <u>One of these is having the opportunity to exercise.</u> A person may access the canyon for his daily jog or walk. He may also do a little bit of hiking.<u> Another benefit is having good quality of water (free from pollutants).</u> The vegetation in the canyon prevents the urban runoff (usually from storms) from polluting the bodies of water.<u> Lastly, it gives the person a chance to see wildlife.</u> Many of the canyons are being preserved; thus, it's an opportunity to see many endangered habitats in it.
