Scientists believe the gases of Earth's atmosphere originated from several sources. Initially, volcanic eruptions released gases such as water vapor, carbon dioxide, and ammonia. Additionally, the process of outgassing from the planet's interior and contributions from comets and meteorites also played a role. Over time, photosynthetic organisms transformed the atmosphere by increasing the levels of oxygen, shaping it into the composition we recognize today.
What else can I help you with?
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
True or False Most of the gases Mercury once had in its atmosphere apparently escaped into space?
True. Scientists believe that Mercury's thin atmosphere is the result of most of its original gases escaping into space due to the planet's low gravity and proximity to the sun.
What causes a meteor to burn?
gases combined with the speed, plus the passing through earths atmosphere. Or to answer in a word........friction!
Which makes up less than 1 percent of earths atmosphere?
Argon and trace gases like neon, helium, and methane make up less than 1 percent of Earth's atmosphere.
How much of the atmosphere does nitrogen gas make up?
Nitrogen makes up about 77% of earths gasses oxegen is 21% of earths gases corbon dioxide is 1% arogon is 1% as well
Where do scientists believe the first gases that created the atmosphere came from?
Scientists believe that the first gases that created the atmosphere came from volcanic activity and the release of gases from the Earth's interior.
What is the makeup of earths atmosphere?
Gases
Where do these main gases come from?
they come from earths atmosphere and gases
Which gases were parts of earths original atmosphere?
HIDROGEN
How do greenhouse gases affect the earths atmosphere?
They slow the loss of heat
Many scientists believe the greenhouses gases?
Many scientists believe that the greenhouses gases have contributed to the climate change due to increased concentrations of the gases in the atmosphere courtesy of human activities such as deforestation, and through fossil fuels.
What are the primary gases found in earths atmosphere?
Nitrogen and oxygen,
Where do most scientist believe earth's early archean atmosphere was formed primarily by gases released from?
Most scientists believe that Earth's early Archean atmosphere was formed primarily by gases released from volcanic activity. This included gases such as water vapor, carbon dioxide, nitrogen, and small amounts of methane. These gases were constantly being emitted by volcanic eruptions, shaping the composition of the atmosphere during that time.
Pairs of gases that are the most abundant in earths atmosphere?
Nitrogen & oxygen.
What part of the earths spheres is composed of a mixture of gases?
the entire atmosphere...
What do scientists believe is causing the temperature of earth a tmosphere to change?
Scientists believe that the increase in greenhouse gases, particularly carbon dioxide, from human activities such as burning fossil fuels, deforestation, and industrial processes is the main cause of the Earth's atmosphere warming. This leads to the greenhouse effect, where these gases trap heat in the atmosphere, causing the planet's temperature to rise.
What are the most common gases that are found in the earths atmosphere?
These gases are nitrogen, oxygen, argon, carbon dioxide.
