Question

Mercury has likely gone through many stages of atmospheric development since its formation.

Match the stage of atmosphere development in the timeline below.

First: "A secondary atmosphere of carbon dioxide and methane form with the planet", "A primary atmosphere of carbon dioxide and methane form with the planet", "A primary atmosphere of hydrogen and helium forms as the planet forms", "A rocky planet forms with no atmosphere"   

Second: "The primary atmosphere is blown away by the energy of the sun", "The secondary atmosphere is absorbed by the planet", "The secondary atmosphere is blown away from collisions with asteroids", "The primary atmosphere is absorbed by the planet"]      

Third: "A primary atmosphere forms from hydrogen and helium that graviationally falls on to the planet", "A secondary atmosphere of carbon dioxide and methane forms from volcanic gases", "A primary atmosphere forms of carbon dioxide as asteroids strike the planet", "A secondary atmosphere of hydrogen and helium froms from volcanic gases"]      

Fourth: "The secondary atmosphere is blown away by the increasing energy of the sun", "The primary atmosphere is blasted away from collisions", "The secondary atmosphere is absorbed by the planet", "The primary atmosphere is absorbed by the planet"]      

Answer 1

Mercury has likely gone through many stages of atmospheric development since its formation.mercury is composed of hydrogen, helium, etc. It is a secondary atmosphiric planet and the atmosphere is blown away due to the enery from sun . but new atmosphere will formed. so a very thin layer of atmosphere for mercury. the table below shows the matched form
