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.

What caused a major change in the composition of Earths atmosphere?
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.
How did earths atmosphere change during precambrian time?
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.
How will the the earths atmosphere change in the future?
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.
How did earths atmosphere change?
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 earths atmosphere traps energy from the sun what does it cause?
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.
How do tsunamis change the earths atmosphere?
cuz they can
What is true about earths atmosphere?
it will always change
What element upon which most modern organisms depend was missing from earth's early atmosphere?
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.
What caused a major change in the composition of Earths atmosphere?
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.
What helped change the earth's atmosphere after it was formed?
The earths atmophere came from your mom!
What was the biggest change in the earths atmosphere between the precambrian and the paleozoic eras?
The origin of free oxygen
As life began to populate earths surface what change was seen in the atmosphere?
more oxygen was consumed
How has the earths atmosphere changed?
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 did the earths atmosphere change composition to become todays nitrogen and oxygen 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
How have microscopes change science?
They basically allowed us to observe micro organisms and started the field microbiology.
How does the atmosphere change when you go to high in an airplane?
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.
How does the amount of change as you travel up through earths atmosphere?
The air molecules spreds out in space so there is not enough air to breathe for us there
