Answer:
Dentistry of gases and mass and distance from sun.
Explanation:
- Out of the 8 planets the earth is an only habitable planet in the solar system till date and thus is called as the blue planet as it has water as the source of life form.
- Other planets like the mars and Venus are likely that of the earth but have a certain amount of variation in their atmospheric composition and characteristics and thus they have different cycles.
- Thus like the variation of the sunlight in the earth equator and the poles, due to the more bulges to the equator areas and less of above.
- Similar is the variation in the gases and the density of the mass of the planets and other four-planet are gas giants and have there own atmosphere surrounded in thick layers.

There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water.
The second assumption is that there is something exceptional about Africa, that while other continents and peoples have got or are getting richer, Africans, for reasons we can think but no longer speak in polite company, choose to remain in poverty. Our capacity to see Africa as divergent lets us off the hook so we don’t have to understand our own complicity in the challenges various African countries face today. It also means we rarely rage as we should against the actions of the corporations and governments that profit from instability, corruption or even inexperience (African negotiators at the climate talks have historically been disadvantaged by their lack of experience and the expectation among western negotiators that they should be grateful with whatever they get).
If there is, then, no innate propensity for corruption, violence or poverty in Africa, then the narratives that fuel the stereotypes need questioning. One possible explanation comes from the Nigerian author Chinua Achebe, who said: “The west seems to suffer deep anxieties about the precariousness of its civilisation and to have a need for constant reassurance by comparison with Africa.” Perhaps it’s not Africa that needs saving, but us.
