You're probably thinking of methane hydrate-clathrate.
No. Nitrogen is triply bonded, and is much more stable at "standard" temperatures than the more electronegative oxygen is.
Tropical zones have stable year-round temperatures because they are so close to the equator that the rotation of the earth doesn't affect it as much as more northern or southern areas.
It's only stable at very low temperatures which can be difficult to maintain in launch situations
Temperatures fall with height in a thunderstorm cell. Temperatures generally fall with height in the atmosphere unless there's an inversion present (and those lead to a stable atmosphere not favorable for thunderstorm development)....So if there's thunderstorms present, temperatures should be falling with height.
H2 technically does contain molecules. Or at least, molecule. H2 is two hydrogens covalently bonded, so that the lowest energy level is filled. Since H2 has two atoms (hydrogen and hydrogen), it is not an element, because there is more than one atom. H2 is a molecule itself. However, in context of nature, it is rare that you would ever find an H2 molecule on its own unless you were working with one in a laboratory. So, if you were considering the whole of an H2 gas, there would be many molecules of H2. Short answer: H2 is a molecule itself. Many H2 means there are many molecules of H2.

the phrase stable temeratures mean the temperatures are just the right temperatures and they bring fair weather.
Yes, it is possible.
When rock changes into metamorphic rock, its appearance, texture, crystal structure, and mineral content change.
Heat labile substances are destroyed or corrupted by heat, for example many proteins lose their structure (unfold) at temperatures considerably lower than boiling point. Heat stable substances maintain form and function at higher temperatures. Heat stable/labile properties are often used in biochemistry to distinguish organic molecules such as enzymes, cell proteins and toxins.
They have stable levels of moisture.
Temperatures on earth are kept stable due to the atmosphere. Other factors are the closeness to the sun, the tilt of the Earth, and several other things.

Tropical zones have stable year-round temperatures because of their close proximity to the equator where they constantly experience the sun overhead.
chlorogenic acid is stable in green coffee, it is unstable at high temperatures and decomposes during roasting, so there fewer chlorogenic acid in a brewed cup of coffee.
The city located further inland can be significantly drier, the city along the coast can have more stable temperatures. Coastal regions tend to be more stable.
Atoms or molecules do chemical reactions to be stable, noble gasses are already stable, so they do not react with other molecules to form chemical bonds
