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.
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.
Does the earth still produce water or do you still have the same amount that was there when the earth was born?
Earth does not produce water. The water currently on Earth is believed to have been here since shortly after Earth formed. Water on Earth goes through cycles between the atmosphere, the oceans, and glaciers.. Some water vapor is released by volcanoes, but this is balanced by water carried into the mantle at subduction zones.
Has the amount of water on earth change since the beginning of time?
no
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 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.
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.
Has the atmosphere of the earth changed since the formation?
yes
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 the earth's atmosphere changed since the earth began?
it has beome more polluted
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.
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.
How many snowflakes have landed on Earth since it was formed?
several.
How did oxygen become to be 21 percent of Earth's atmosphere?
Since 79% of earth's atmosphere is all living and non living things. The remainder of that which is 21% would be oxygen.
How the composition of gases change as you travel through the earth's atmosphere?
As the gases go higher in the atmosphere they start to compose or join together at some point which causes them to change since there is mixture of more than one gas, sometimes they form a different element when certain gases form
