Oxygen
Earths atmosphere has changed in a few ways. It contains more pollutants and carbon dioxide which is a greenhouse gas.
photosynthesis
The atmosphere has changed because of population increases and lots of factories that produce the gas. Olivia Perli
It changed from a reducing atmosphere containing no free oxygen to an atmosphere containing oxygen. The evolution of life on Earth "terraformed" the planet.
The particles outside the Earths atmosphere are called, meteoroids.

Earth's early atmosphere was primarily composed of carbon dioxide. Early bacteria used carbon dioxide as a source of fuel and as a result produced oxygen.
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.

how do geologists think earths atmosphere is formed
