How oxygen originated earth

How oxygen originated earth

Oxygen didn’t just get onto earth, it was created here, by plants known as cyanobacteria or blue-green algae. These and all other plants use a method known as photo-synthesis, which is when plants use energy from the sun to convert carbon dioxide into oxygen

Oxygen can’t be kept or imprisoned in the earth’s

atmosphere, some oxygen gas escapes, some reacts

with different particles to create stuff like other gasses and some is re-converted into carbon-dioxide from breathing organisms.

Most of our oxygen that is created today, is

supplied from large rain forests.

What is a gas nebula

What is a gas nebula

  • Gas Nebulae (plural for Nebula) are interstellar clouds made from gasses (mostly hydrogen) and dust particles, most of these dust and gas particles can come from large explosions. There are different types of gas nebulae that can vary in size, shape, colour etc. (gas Nebulae don’t do the same things as one another)

  • For example:

  • The stellar nursery frequently emits light rays from the newborn stars it creates while the crab Nebula is just gas and dust remains from a supernova, this gas and dust is visible because it reflects the lights from other stars.

  • The stellar nursery creates stars when large amounts of dust particles fall in on itself under it’s own weight, when the stars created it lets off large amount of UV rays.
