Explanation:
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.
The answer is C. Mikhail Gorbachev helped the Soviet Union improve relationships with the US.
Rock types and elevation
Explanation:
Most boundaries between landscape regions are usually indicated by sharp changes in rock types and elevation.
Some times we move from a region dominated by igneous rocks to metamorphic terrains and so on.
- Abrupt lithological changes are usually evident when we cross landscape regions.
- Also the elevation between the two places can change.
- Most times when we move from the inland to the coastal areas, we notice that elevation decreases rapidly.
- Rock types and elevation are good indicators of changes in landscapes.
