The development of an ozone layer in Earth's atmosphere allowed organisms to move onto land. The ozone layer absorbs the sun's harmful ultraviolet radiation, providing protection for early land-dwelling organisms. This helped pave the way for the colonization of land by plants and animals.
One major change in the composition of Earth's atmosphere was the Great Oxidation Event about 2.4 billion years ago. This event led to a significant increase in oxygen levels due to the emergence of photosynthetic organisms that released oxygen as a byproduct. This change had a profound impact on the evolution of life on Earth.
During the Precambrian time, the Earth's atmosphere underwent significant changes, transitioning from a reducing atmosphere dominated by gases like methane and ammonia to an oxidizing atmosphere with increasing levels of oxygen, due to the development of photosynthetic organisms. This increase in oxygen levels laid the foundation for the evolution of complex multicellular life forms.
The earth's atmosphere is projected to change due to human activities, leading to increases in greenhouse gas concentrations and global temperatures. This will likely result in more extreme weather events, rising sea levels, and changes in precipitation patterns. Adapting to these changes and reducing emissions are key to mitigating the impacts on the atmosphere.
The Earth's atmosphere has changed over time due to various factors such as volcanic activity, changes in greenhouse gas concentrations, and natural variations in solar radiation. Human activities, such as the burning of fossil fuels and deforestation, have also significantly impacted the composition of the atmosphere, leading to an increase in greenhouse gas emissions and global warming.
When Earth's atmosphere traps energy from the sun, it causes an increase in temperature on the surface of the Earth, known as the greenhouse effect. This can lead to global warming, climate change, and various environmental impacts.
cuz they can
it will always change
Oxygen was the element missing from Earth's early atmosphere, which eventually accumulated due to early photosynthetic organisms. This change in the atmosphere allowed for the evolution of organisms that rely on oxygen for respiration.

The earths atmophere came from your mom!
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.
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
They basically allowed us to observe micro organisms and started the field microbiology.
The air becomes less dense, the higher you go. And generally, the temperature gets colder until you reach the thermosphere, which is the hottest part of Earths atmosphere.
The air molecules spreds out in space so there is not enough air to breathe for us there
