How much as the temperature of the earth increased since the earth was formed?
Considering the Earth was Molten when it was formed, the temperature has actually decreased.
Why have the levels of carbon dioxide changed since the early earths atmosphere?
The atmosphere has changed because of population increases and lots of factories that produce the gas. Olivia Perli
What percent of time since earth was formed have humans lived on earth?
When calculated according to the 4.6 billion years since earth was formed humans have live in it 0.09 percent of the time.
Which of earth's atmosphere layers is the most dense?
The troposphere is the most dense since it is closest to the surface of the earth and has the highest pressure.
How has the Earth's atmosphere changed since the beginning of time?
The atmosphere 4.5 billion years ago was mostly Carbon Dioxide from volcanoes with little or no oxygen in the air. Though, through the process of photosynthesis there is now 71% of Nitrogen, 21% of Oxygen and 0.3 % of water vapour and Carbon Dioxide!
Has the atmosphere of the earth changed since the formation?
yes
How has the earth's atmosphere changed since the earth began?
it has beome more polluted
What type of atmosphere is present when earth is formed?
The atmosphere of Earth has changed since its formation. When the Earth formed 4.6 billion years ago, it was a molten ball of rock with an atmosphere of hydrogen and helium. This atmosphere was blown away by the solar winds because there was no magnetic field to protect the Earth. After the Earth cooled, volcanoes released gases such as water vapour, ammonia and carbon dioxide. The ammonia was broken down into nitrogen and hydrogen by sunlight. Eventually, the evolution of cyanobacteria released oxygen into the atmosphere, which began to have a similar composition to the modern atmosphere.
Why do events happen?
Catastrophic weather events have happened since the Earth was formed. They can happen when things in the atmosphere radically change.

How has the atmosphere changed since the origin of the earth?
since human is been on this planet our atmosphere had gotten into several changes like increase in temperature,unstable weather,etc.humans have also increased the level of carbondi-oxide in our atmosphereetc.
How much as the temperature of the earth increased since the earth was formed?
Considering the Earth was Molten when it was formed, the temperature has actually decreased.
How has earth atmosphere changes since it first formed?
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 old is the atmosphere?
The Earth is about 4.5 billion years old and has had an atmosphere since it formed, but about 3.8-4.1 billion years ago there was believed to be the Late Heavy Bombardment, where a planetesimal roughly the size of Mars hit the Earth, breaking off a large chunk that formed into the Moon. This impact would have obliterated the atmosphere, but it has reformed naturally since then. So, the answer to your question is approximately 4 billion years old.
