How Did the Earth Get Warm?
Earth is the second planet from the Sun and only celestial object known to support and harbour life. About 29.2 % of the earth’s surface is land consisting of islands and continental shelves. The remaining portion is covered with ocean which is an extremely vast ocean composed of different ocean species. A thin barrier-like atmosphere surrounds the earth, where it absorbs heat from the sun in the process producing clouds. Most of the living organisms live below the ocean floor, while plants, animals and micro organisms dwell on the land.
The earth orbit is tilted beneath the plane of the ecliptic curve which is inclined by about forty-six degrees from the geographic north pole to the southern hemisphere. This tilt is about four degrees above the seasonal mean axis of the earth which is tilted about zero degrees in the northern hemisphere. Due to its tilt, the earth rotates in a clockwise motion around its axis of symmetry whereas the tilt of the tilt axis of the earth is about twelve degrees from horizontal. The tilt of the earth’s axis of symmetry keeps the earth within a circular orbit that has an average circumference of around Centigrade and an axis of spin approximately tangential to the plane of the ecliptic curve. Thus the earth revolves around its own axis of symmetry and is subject to oblate and deflate without affecting the angular momentum of the earth.
The tilt of the earth also allows the earth to be placed in a variety of orbit planes. For instance, some scientists think that the earth may be placed between two orbital planes that are tilted by about ten degrees. The scientists argue that the equator would be the plane that would receive the largest elongation of the earth’s orbit as it passes through this plane. Evidence of this is the existence of tilted surfaces on some of the largest rock formations such as the Grand Canyon and the Great Wall of China.
The earth has poles and areas where there is no liquid water, while other areas have sufficient amounts of liquid water. The earth’s poles are known for being very cold places, while other areas have sufficient warm temperatures to support the existence of liquid water under the earth’s surface. The poles are known for their large ice sheets that cover the polar caps, while other areas have substantial amounts of snow that fall to the ground in the winter months. The presence of water or liquid water indicates that the earth is capable of storing heat long enough to allow for human beings to live on the planet.
All the evidence indicates that the earth has a very consistent composition and structure, which are inconsistent with a world that is composed of a rocky core and a molten ocean floor. The composition of the earth’s interior implies that there must be a source of excess heat deep within the earth’s crust, which has resulted in the development of tectonic plates. The development of plateaus inside the earth indicates that there must be a means for heat to escape from the interior of the earth, which in turn leads to the question how did the earth get warmer? Scientists believe that the answer to this question can be found through the study of the composition of the earth’s crust.
Evidence suggests that the earth got its heat from a star system that existed long before the earth was born, which would make the earth much older than scientists believe it to be. A study of the composition of the earth shows that plate tectonics must have been present when the earth was created in its present form, which would indicate that the earth would have been made to resemble the sun more closely. Evidence indicates that the earth would have cooled very quickly due to solar radiation, which would account for its very thick atmosphere. The present day sun is far too distant to have any effect on the composition of the earth, while the earth would have warmed up very quickly due to the radiation coming from stars in our galaxy.
