Mercury and the Moon do not have significant atmospheres. Mercury's thin exosphere mainly consists of atoms blasted off its surface by the solar wind, while the Moon has virtually no atmosphere, making them both airless bodies in our solar system.
Two types of planets are terrestrial planets, which are small, rocky planets like Earth, and gas giant planets, which are large planets primarily composed of hydrogen and helium, such as Jupiter and Saturn.
There are two main types of planets because the two categories separate the planets into more specific groups. 1. Terrestrial planets have a rocky surface and are inside of the asteroid belt that separates the Terrestrial planets from the Gas Giants The Terrestrial planets are: (in order of distance to the sun (close to far) Mercury, Venus, Earth, and Mars. 2. Gas Giants are mostly made up of gasses and are very large in size Gas Giants are: (in order of distance to the sun (close to far) Jupiter, Saturn, Uranus, and Neptune.
the US is not in the southern atmosphere. it is in the northern atmosphere. northern is on the north of the equator.
The atmosphere is heated from below because the Earth's surface absorbs solar radiation, which warms the ground. The warm ground then heats the air in contact with it through conduction and convection, causing the lower atmosphere to be warmer than the upper atmosphere. This temperature difference sets up vertical air movements that drive weather systems and the circulation of the atmosphere.
No many like Mars have no atmosphere at all.
An atmosphere is a layer of gas that is part of a planet, and usually surrounds it solid part, if there is a solid part. so for each planet, there is one and only one plant in its atmosphere. The earth is the only planet in the Earth's atmosphere; Mars is the only plant in the Martian atmosphere; etc.,
The atmosphere protects the inner planets the same way as for meteors.
there are many planets in fact. saturnis one example
The atmosphere gets thicker and thicker as you go down; the planets basically consist mainly of atmosphere, though those planets are expected to have a solid core.
Space does not have an atmosphere. It is generally considered a vacuum. Planets and some moons have atmospheres.
ans2, There are as many atmospheric and surface compositions as there are planets with atmosphere or surface.You'll have to be more specific if you want useful data.
the outer planets are gaseous and the inner planets are not
If by gas you mean an atmosphere, there are no planets with an atmosphere anywhere similar to Earth.
It protects the inner planets from ultraviolet radiation
There are probably a very great number of planets in our galaxy with no atmosphere. Of the 400+ planets that we know of, we can only determine the presence or absence of an atmosphere for the 8 planets in THIS solar system; our technology is not yet good enough to study atmospheres from several light-years distance. Of the planets of this solar system, we are fairly sure that Mercury has no atmosphere to speak of. Of the other seven, we know that Mars has a very thin atmosphere, but enough to use a parachute in. If we include dwarf planets, we can say with some certainty that Ceres doesn't have enough mass to retain an atmosphere, and Pluto's atmosphere is almost certainly all frozen by now.
yes.
