What did scientists hypothesize about earths early atmosphere and the way the ocean was formed?
The first ever atmosphere was hydrogen and helium (they call this the primary atmosphere) because these elements are light they were knocked off due to solar storms (charged particles from the sun)
The dense rocks that formed the and the vast temperatures beneath caused many volcanic erupts which spat out carbon monoxide, carbon dioxide, ammonia, hydrogen sulphide, methane and water vapour forming the secondary atmosphere, these heavier elements did not get "knocked" off by solar storms. As the surface of the earth began to cool the water vapour in the atmosphere condensed into perciperation(rain) which ultimately over-time continued to cool the earths surface and make the oceans in the depressions in the earths surface. The oceans are salty because they erode away at the rocks and other elements beneath the surface.
The ocean and rain began to dissolve the ammonia and carbon dioxide in the atmosphere, ultraviolet light shining through the earths atmosphere also broke down water molecules into hydrogen and oxygen and broke remaining ammonia that (in effect is too high) to be dissolved by the ocean into nitrogen and hydrogen.
The combination of nitrogen, hydrogen, oxygen (and of course other small amounts of other elements) is what are atmosphere is now made of.
Makes you wonder what could happen to change our atmosphere in the future, let's hope not too dramatically so we have atleast some time to evolve? :p
What else can I help you with?
Are ions in the earths atmosphere?
Yes, ions can be found in the Earth's atmosphere. These ions are often formed from the interaction of sunlight with molecules in the atmosphere, such as nitrogen and oxygen. Ions play a role in processes like lightning strikes and the formation of the Earth's ionosphere.
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.
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.
What was Earths first atmosphere was created by?
The earths first atmosphere was created by the methane, carbon dioxide, sulphur oxides and water vapor that volcanoes were pumping out. Oxygen started to come in noticeable quantities once life had formed. Nitrogen is inert, so doesn't do anything.
What era is when earths atmosphere formed?
The Earth's atmosphere began forming approximately 4.5 billion years ago during the Hadean Eon, following the planet's formation. This initial atmosphere was likely composed of gases released from volcanic activity and impacts from comets and asteroids.
Scientists hypothesize that Earth's early atmosphere was formed primarily by gases released by?
Volcano Eruptions
How do geologists think earths atmosphere formed?
how do geologists think earths atmosphere is formed
What do Scientists hypothesize that the sun formed from?
Scientists hypothesize that the sun formed from a massive cloud of gas and dust known as a solar nebula. This cloud collapsed under its own gravity, leading to the formation of the sun at the center of the solar system.
What does scientists hypothesize regarding the sun and the planet?
Scientists hypothesize that the sun and planets formed from a giant molecular cloud of gas and dust in a process called accretion. They believe the sun formed at the center and the planets accreted from the disk of material surrounding it. This is known as the nebular hypothesis.
How old is the earths atmosphere?
The earth's atmosphere is very old. It was formed when earth was formed.
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
What helped change the earth's atmosphere after it was formed?
The earths atmophere came from your mom!
Which force do scientist hypothesize formed your solar system?
Gravity.
What igneous rock formed from lava have a fine?
Volcanic (Extrusive) igneous rock, which are formed by lava that comes out of the earths crust, then cools and solidifies rapidly on the earths surface due to exposure to the environmental atmosphere.
Why scientists hypothesize that chemical events preceded the origin of life on earth?
Scientists hypothesize that chemical events preceded the origin of life on Earth because organic molecules, essential for life, can be formed through non-biological processes like chemical reactions and catalysis. Studying these chemical events can provide insights into how the building blocks of life may have formed on early Earth before biological processes took over.
Scientist hypothesize that the sun formed?
Scientists hypothesize that the sun formed from a giant cloud of gas and dust in space, known as a solar nebula. As gravity caused the nebula to collapse, most of its material gathered at the center to form the sun, while the remaining material formed the planets, moons, and other objects in the solar system. This process is known as the nebular hypothesis.
Are ions in the earths atmosphere?
Yes, ions can be found in the Earth's atmosphere. These ions are often formed from the interaction of sunlight with molecules in the atmosphere, such as nitrogen and oxygen. Ions play a role in processes like lightning strikes and the formation of the Earth's ionosphere.
