Plants utilize carbon dioxide (CO2) to perform photosynthesis. This is fortunate, because all living things produce CO2 as a byproduct of respiration and oxidation. If the plants didn't absorb it, it would build up in the atmosphere to dangerous levels, and life as we know would cease to exist.
The plants would no longer put out oxygen, and the concentration of carbon dioxide would increase dramatically in the atmosphere.
your question is... How did the Earth`s atmosphere change composotion to became today`s nitrogen and oxygen atmosphere? Answer: it happend with the help of solar untraviolet (uv) radiation,the very thing what we worry about now for its cancer-causing ability
By slowing down the earths rotation but will not make effect to humans .
They smooth earths surface
L
water, ice, wind, and snow.
cuz they can
it will always change
Earths atmosphere has changed in a few ways. It contains more pollutants and carbon dioxide which is a greenhouse gas.
Photosynthesis drastically increased the oxygen content of the atmosphere.
it will rise
The earths atmophere came from your mom!
The appearance of photosynthetic organisms
The eruption of a very large volcano
The origin of free oxygen
more oxygen was consumed
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
It changed from a reducing atmosphere containing no free oxygen to an atmosphere containing oxygen. The evolution of life on Earth "terraformed" the planet.
