The two gases that are most common in interstellar clouds,consist mostly of gas,especially hydrogen and helium.
Since interstellar clouds are most often overdensities in the interstellar medium, they have overwhelmingly similar chemical compositions - most of them (about 90%) being hydrogen, although this may be molecular, or ionized (plasma), with most of the remainder being helium. Heavier elements and compounds have been discovered spectroscopically in interstellar clouds, including more recently some unexpected light organic molecules.
The most abundant molecule in interstellar clouds besides molecular hydrogen is carbon monoxide (CO). It is frequently used by astronomers as a tracer for studying the presence of molecular clouds and star formation activities.
cirrus clouds are the most highest clouds and the most common
cummulus clouds
Red light passes most easily through interstellar clouds because it has the longest wavelength and lower energy, making it less likely to be absorbed or scattered by dust particles within the cloud. Blue and violet light, with shorter wavelengths and higher energy, are more likely to be scattered or absorbed.
Cumulonimbus clouds are most common in hurricanes. These clouds are large, dense, and capable of producing heavy rainfall and thunderstorms. They are characteristic of the intense convection and strong updrafts found in hurricanes.
Nitrogen and Oxygen are the most common gases in the atmosphere.
The two most common gases in Earth's atmosphere are nitrogen (approximately 78%) and oxygen (approximately 21%).
No, most molecules found in giant molecular clouds are not based on silicon. Instead, they are primarily composed of elements like hydrogen, helium, carbon, oxygen, and nitrogen, which are more abundant in the universe. Silicon-based molecules are less common in interstellar environments.
nitrogen and oxygen
Most of the universe is made up of hydrogen gas, followed by helium. These two gases are the most abundant elements in the universe and can be found in stars, galaxies, and interstellar space.
Cumulonimbus clouds cann occur at any time of year, but are most common in the summer.
