What else can I help you with?
Earths early atmosphere formed during the early Archean era which gas was generally absent from the atmosphere at that time?
Oxygen Please study this, & don't forget it so you don't have to keep looking up answers .
What is earths Precambrian atmosphere?
The Earth's Precambrian atmosphere was primarily composed of carbon dioxide, methane, ammonia, and water vapor. It lacked oxygen and had higher levels of greenhouse gases compared to the present atmosphere. This environment supported the evolution of early life forms such as bacteria and algae.
Which gases made up most of Earths early atmosphere?
Earth's early atmosphere was primarily composed of carbon dioxide, water vapor, nitrogen, and smaller amounts of methane and ammonia. Over time, volcanic activity and chemical reactions led to the formation of oxygen and the development of the current atmosphere.
Why gas was lacking from earths early atmosphere in the early Precambrian era?
Gas was lacking from Earth's early atmosphere in the early Precambrian era because the primitive atmosphere was composed mainly of hydrogen and helium, which were lost over time. The formation of the Earth's magnetic field and the development of the ozone layer prevented the atmosphere from being stripped away by solar winds, leading to the accumulation of gases like carbon dioxide and water vapor over billions of years.
What was the early atmosphere of Earth composed of?
The early atmosphere of Earth was predominantly composed of carbon dioxide, water vapor, nitrogen, and trace amounts of methane and ammonia. There was little to no oxygen present during this time.
How did bacteria change early earths atmosphere?
Earth's early atmosphere was primarily composed of carbon dioxide. Early bacteria used carbon dioxide as a source of fuel and as a result produced oxygen.
What gas was lacking from earths early atmosphere in the early precambrian?
oxygen
What gas was not part of early earths atmosphere?
oxygen
What gas was not a part of earths early atmosphere?
nitrogen
Was the earths early atmosphere made up of mostly oxygen?
no
What was the major contributor of oxygen to earths early atmosphere?
photosynthsis
Earths early atmosphere formed during the early Archean era which gas was generally absent from the atmosphere at that time?
Oxygen Please study this, & don't forget it so you don't have to keep looking up answers .
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
What is earths Precambrian atmosphere?
The Earth's Precambrian atmosphere was primarily composed of carbon dioxide, methane, ammonia, and water vapor. It lacked oxygen and had higher levels of greenhouse gases compared to the present atmosphere. This environment supported the evolution of early life forms such as bacteria and algae.
What factor contributed to the formation of earths early atmosphere?
energy from the sun,lightening,earths heat triggered chemical reaction for the early gases of the earth combined
What gas do scientist think was missing from earths early atmosphere?
Methane gas
What does gas do to some scientist think was missing from earths early atmosphere?
oxygen
