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.
Answer:
Glacial retreat occurs when ice melts faster than it forms.
Explanation:
Glaciers are large, slow-moving masses of land ice formed by the recrystallization of snow. For complex reasons, if the worldwide climate becomes cooler, and snow accumulates faster than it melts, the glaciers grow larger and cover more land. 10% of the Earth's surface today is covered by glaciers. Antarctica and Greenland are virtually covered by glaciers. At the height of past glacial ages, 32% of the Earth was covered by glacial ice. Most of Chicago is covered by glacial or glacial-related deposits.
Greenhouse (warm) periods: extensive and prolonged volcanic activity produces excessive carbon dioxide Thus based on above the glaciers have been melted in the recent past and still continue.
Apart from this, the climate will cool again at the end of global warming and climate change. The natural cycle will change and raising the carbon content along with sea levels.
Answer:
The complete option include
The sun is located slightly off center from the middle of each planets orbit
Inner planet orbits the sun at higher orbit than that of the outer planet
Earth is slightly closer to the earth on one side of its orbit than other side
All the planets orbit the sun in one plane
Venus orbits the sun faster than earth
Pluto moves faster when it is closer to the sun than when it farthest
Explanation:the correct answer are
The sun is located slightly off centre from the middle of each planet
Earth is closer to the sun on one side of its orbit than the other
