Exosphere
True. The troposphere is the lowest layer of Earth's atmosphere and contains approximately 75-80% of the total mass of the atmosphere.
Troposphere contains nearly all of the atmosphere's clouds. This is for 2 reasons: first, almost all water vapor is contained in this layer. Second, the air is inherently unstable, since it is warmest at the bottom. The causes the air to always want to rise, creating clouds under the right conditions.
The thermosphere is the "hottest" layer of the Earth's atmosphere. As the outermost layer with substantial numbers of molecules, it receives the most direct radiation from the Sun. However, despite the high molecular temperatures measured in this layer (as high as 2500°C or 4530°F), the matter is tenuous compared to the lower atmosphere. An object within the thermosphere would absorb very little total heat energy. Almost all satellites, and the International Space Station, orbit within the thermosphere. The layer periodically varies in thickness, stretching from about 80 kilometers in altitude to between 250 and 500 kilometers. The thermosphere.
Mars has almost no atmosphere. APEX=MERCURY has no atmosphere.
We consider the Moon to have no atmosphere. There are traces of radon and a few other things resulting from the out-gassing of rock on the surface, but there just isn't enough to really answer this question in the affirmative. The reason the Moon has no atmosphere is that it's gravity is too slight to "hang on to one"

The Exosphere is the layer in the atmosphere that is closest to outer space.

Yes, the troposphere contains almost 75-80% of the total mass of the Earth's atmosphere. It is the layer closest to the Earth's surface and is where most weather phenomena occur.
indeed it does. each successive layer contains less and less gas. (the last layer is almost like outer space actually) so yes the troposhere contains almost all atmospheric gas
The composition of the atmosphere of Saturn is almost entirely made up of hydrogen, at 97%, and helium, at 3%. It also contains trace amounts of methane, at about 0.05%.
The lowest layer of the atmosphere is the troposphere. It contains almost all of the atmosphere's water vapor and weather activity, such as clouds, precipitation, and winds. The troposphere extends from the Earth's surface up to about 8-15 kilometers in altitude.
The troposphere is the layer of the atmosphere that contains almost all of the Earth's water vapor. It is the lowest layer of the atmosphere, where weather occurs and where most of the water cycle takes place.
