The four major components of Earth's atmosphere are nitrogen (78%), oxygen (21%), argon (0.9%), and carbon dioxide (0.04%). These gases help regulate temperature, support life, and protect against harmful radiation.
I live on Reigel VII so four components of my planet are a solid iron core, a molten berilium mantal, a crust made of fudge, and a oxygen rich atmosphere.
