Atmosphere

In the Urantia Book

Terrestrial atmospehere

• the primitive atmosphere which appeared as a result of the internal elemental contest between the heated interior and the cooling crust. 57:7.2
• terrestrial atmosphere slowly evolving between one billion to one and a half billion years ago 57:7
• the high degree of carbon in the atmosphere afforded the new land varieties of life opportunity for speedy and luxuriant growth. 58:1.8
• The elevation of the continents proceeded, and the atmosphere was becoming enriched with oxygen. 59:4.17
• 160 millions years ago the land was largely covered with vegetation adapted to support land-animal life, and the atmosphere had become ideal for animal respiration. 59:6.10
• Were it not for the “blanketing” effect of the atmosphere at night, heat would be lost by radiation so rapidly that life would be impossible of maintenance except by artificial provision. 58:2.5
• The height of the earth’s atmosphere is indicated by the highest auroral streamers—about 400 miles. 58:2.6
• the atmosphere of Urantia thins out increasingly until at about 3,000 miles it begins to shade off into the average space matter in this section of the universe. 42:4.6

Atmospehere in other planets

• the atmosphere is present on all evolutionary planets if they are not too small 41:10.3

Atmospehere in morontia spheres

• the atmospehere of morontia spheres is comprised of oxygen, nitrogen, and a morontia gas suitable for the respiration of morontia creatures 43:1.3
