Which two gases have been added to earth's atmosphere in large amounts and are believed to have increased global warming by absorbing infrared radiation?
Carbon dioxide and methane are the two main gases that have been added to Earth's atmosphere in large amounts due to human activities such as burning fossil fuels and livestock farming. These gases are known as greenhouse gases as they trap heat in the atmosphere, leading to increased global warming by absorbing and trapping infrared radiation.
What gas was not plentiful in earth's early atmosphere?
Oxygen was not plentiful in Earth's early atmosphere. Instead, it is believed that the atmosphere was composed mainly of carbon dioxide, nitrogen, and water vapor. Oxygen levels increased significantly over time due to the process of photosynthesis by early life forms.
What is the current atmosphere of Earth believed to be?
The current atmosphere of Earth is primarily composed of nitrogen (78%) and oxygen (21%), with trace amounts of other gases like carbon dioxide, methane, and water vapor. Human activities, such as burning fossil fuels, have increased levels of greenhouse gases like carbon dioxide, leading to concerns about climate change and global warming.
What is the source of earths original atmosphere?
Earth's original atmosphere is believed to have been formed by outgassing from the planet's interior, which released gases such as water vapor, carbon dioxide, and nitrogen. These gases accumulated around the young Earth to create the primordial atmosphere.
Where did the earths present atmosphere originate?
Earth's present atmosphere is believed to have originated from volcanic activity early in the planet's history. Volcanoes released gases such as water vapor, carbon dioxide, and nitrogen, which eventually formed the atmosphere over billions of years.

How is carbon in any form given out in the atmosphere?
It enters our atmosphere through dead animals, tress and any decaying or burning item that lived. It is believed by some that the change in our atmosphere of concentrations of CO@ may be as high as 0.007%. Some feel this number is wildly high.Oceans provide the largest sink for absorbing this CO2 from our air. Forests provide the largest generator for CO2. Man produces roughly 6% of all CO2 in our atmosphere.
What kind of radiation does a black hole emit?
Black holes are believed to emit something called Hawking radiation.
What is Neptune's atmosphere's most abundant gas?
About 85% of Neptune's atmosphere is believed to be made up of Hydrogen.
Darwin believed that the various species of finches on the Galapagos Islands came from one common ancestor He believed they evolved by?
adaptive radiation
Why is the atmosphere on Venus filled with sulfur?
That's believed to be a byproduct of volcanism, though the atmosphere is mainly filled with carbon dioxide.
How ia cosmic background radiation related to the big bang theory?
The cosmic background radiation is believed to be the remains of the radiation emitted by the Universe when it started to get transparent - when it had cooled down to a temperature of about 3000 kelvin.
What is the only moon in the solar system believed to have a substantial atmosphere?
Titan - a moon of Saturn - has a substantial atmosphere comprised of mainly nitrogen.
Why does Titan have such a nitrogen-rich atmosphere?
Titan's nitrogen-rich atmosphere is believed to be the result of outgassing from its interior, along with the capture of nitrogen and other volatile compounds from the early solar nebula. The lack of substantial geological activity on Titan has allowed the atmosphere to retain these gases over time.
What is the current atmosphere of Earth believed to be?
The current atmosphere of Earth is primarily composed of nitrogen (78%) and oxygen (21%), with trace amounts of other gases like carbon dioxide, methane, and water vapor. Human activities, such as burning fossil fuels, have increased levels of greenhouse gases like carbon dioxide, leading to concerns about climate change and global warming.
Did volcanoes create life?
After loss of the hydrogen, helium and other hydrogen-containing gases from early Earth due to the Sun's radiation, primitive Earth was without an atmosphere. The first atmosphere was formed by gases leaking out from the interior of the early Earth, which still goes on today in volcanoes. Without an atmosphere, life would not have formed.
