In the Earth's atmosphere.
Nitrogen gas is most commonly found in Earth's atmosphere, which is part of the geosphere. It makes up about 78% of the Earth's atmosphere and plays a crucial role in supporting life.
Helium is most commonly found in the Earth's crust, often in natural gas deposits. It can also be found in the atmosphere in small amounts. Helium is not typically found in significant quantities in the oceans.
Helium is most commonly found in natural gas deposits deep underground, where it is produced as a byproduct of the natural decay of radioactive elements. It is also found in small amounts in the Earth's atmosphere, although it is typically extracted from natural gas reserves.
No. The most common rock found on the surface of the Earth is sedimentary rock, and in particular, shale, sometimes referred to as mudrock).
Most Basalt is found mostly in oceanic plates of Earth.
Argon-40 is the most commonly found isotope of argon on Earth, with a natural abundance of about 99.6%. This isotope is stable and is produced from the radioactive decay of potassium-40 in the Earth's crust.
Igneous rock, and specifically basalt.
The minerals containing erbium are xenotime, euxenite, monazite, gadolinite, some clays.
The universe is mostly comprised of empty space and therefore the helium is found in certain places. It is found on Earth and some other planets, but it is most commonly found in stars such as the Sun.
