Answer:Atmosphere
Explanation:
Moon is smaller in size than earth and hence, has very low force of gravity. Moon does not have atmosphere as its weaker force of gravity can not hold the atmosphere. Any present atmosphere on moon would have stripped away by strong solar wind. The weaker magnetic field of moon is one more reason for absence of atmosphere.
Hydrogen
followed by carbon, oxygen, and then nitrogen.
Peripheral would be the answer
Answer:
parallel and intersect at right angles
Explanation:
The roads in the urban areas tend to be very well organized and constructed. They tend to be parallel to each other, and also to intersect at right angels. The reason for this kind of building of the roads in the urban areas is to make the movement in the urban areas much easier and more efficient, mostly putting the accent on the traffic. It is a fact that the traffic is a big problem in the urban areas, so by constructing the roads in a well organized manner, the traffic jam eases up and the citizens can move more easily and quickly.
