what are the different stages of development of atmosphere
Answers
Its early atmosphere was probably formed from the gases given out by volcanoes. The early atmosphere was probably mostly carbon dioxide, with little or no oxygen. There were smaller proportions of water vapour, ammonia and methane. As the Earth cooled down, most of the water vapour condensed and formed the oceans.
QUESTION:-
what are the different stages of development of atmosphere
ANSWER:-
There are three stages in the development of the existing atmosphere.
- The first stage is noted by the loss of primordial atmosphere.
- The second stage is marked as the hot interior of the earth which provided the evolution of the atmosphere.
- In the third stage which is the final stage, the composition of the atmosphere was adapted by the living world through the process of photosynthesis.
NOTE:-
When Earth has formed 4.6 billion years ago through a hot mixture of gases and solids in that period it had nearly no atmosphere. The surface of the Earth was molten.
When the Earth cooled down then an atmosphere was formed primarily from gases spewed from volcanoes
The existing composition of the earth's atmosphere is chiefly contributed by nitrogen and oxygen.
