What was the source of earth early atmosphere?
The early Earth's atmosphere was primarily composed of gases released from volcanic activity, such as water vapor, carbon dioxide, nitrogen, and small amounts of methane and ammonia. These gases formed the primitive atmosphere over millions of years as the Earth cooled and solidified.
What process removed most of the water vapor from Earth's early atmosphere?
The majority of water vapor from Earth's early atmosphere was removed through a process called outgassing, where water vapor condensed and formed oceans as the planet cooled. Additionally, the formation of rocks and minerals also absorbed water from the atmosphere.
What gases were probably abundant in the earths early atmosphere?
It is believed that the early Earth's atmosphere likely consisted of gases like water vapor, carbon dioxide, nitrogen, and methane. Over time, as the Earth cooled and life forms evolved, the composition of the atmosphere changed due to processes like photosynthesis.
How did land atmosphere and oceans form on earth?
Land, atmosphere, and oceans formed as Earth went through processes like planetary accretion and differentiation. The early Earth was primarily molten due to intense heat from collisions with other celestial bodies. As it cooled, the outer layers solidified into a crust, allowing water vapor to condense and form oceans. The atmosphere developed from gases released by volcanic activity and the outgassing of the Earth's interior.
What gas was a thought by Oparin to be part of the early Earth's atmosphere?
He thought that the early Earth's atmosphere contained ammonia, NH3; hydrogen gas, H2; water vapor, H2o; and compounds made of hydrogen and carbon, such as, CH4.

How did volcanoes affect the early earths atmosphere?
Early volcanoes discharged different combinations of gases into the Earth's atmosphere creating rain, which cooled the planet and formed solid land masses, and every other element discovered presently.

What happened to the water vapor when the earth cooled 3 billion to 3.5 billion years ago?
When the Earth cooled between 3 to 3.5 billion years ago, the water vapor in the atmosphere began to condense as temperatures dropped. This led to the formation of liquid water, resulting in the creation of oceans. The cooling process allowed for the stabilization of the Earth's surface and played a crucial role in the development of early life forms and the planet's hydrological cycle.
What would have happened if there was no life on earth?
Not a lot! Early life transformed the atmosphere; removing much of the carbon dioxide, so without life Earth would probably have an atmosphere and environment like Venus.
What happened to the water vapour that was in the early atmosphere?
The water vapor in the early atmosphere of Earth likely condensed and fell as rain, contributing to the formation of the oceans. This process, known as the "water cycle," involves the continuous movement of water between the atmosphere, land, and oceans through processes like evaporation, condensation, and precipitation. Over time, the oceans became the primary reservoir for water on Earth, where it remains today.
Is the earth's atmosphere always the same?
No. The early Earth's atmosphere contained a lot of ammonia, for example.
What molecule could not have been present in an early earth atmosphere and why?
Ozone (O3) could not have been present in an early Earth atmosphere because it is a product of oxygen reacting with ultraviolet radiation. Early Earth's atmosphere lacked the high levels of oxygen needed for ozone formation.
What is one of the gases in the atmosphere of early earth?
dioxide
Earth early atmosphere was first changed by?
photosynthesis
