Model Answer: [13th July 2020]: Discuss various theories explaining formation of the Moon. How has recent findings by NASA's Lunar Reconnaissance Orbiter (LRO) modified our understanding about the origin of the Moon? (15 marks, 250 words) [GS1 - Geography]
Moon, around 1/4th the size of earth and orbiting 3.8 lakh kms away from it, is it’s only natural satellite. The question about how Moon was formed has intrigued scientists for long and over the years, many different theories have been proposed:
1) In 1838, George Darwin suggested that initially both Earth and Moon were a single body, which over the period took a dumbbell shape and separated into two different bodies.
2) Some scientists also suggest that depression which is currently filled by the Pacific Ocean may have been the source of material from which Moon has been formed.
3) But, the Big Splat theory is the most popular one. Here, Scientists suggest that around 4.5 billion years ago, when Earth was just formed, a body of around same size of that of Mars collided with Earth and separated a big mass from it. This mass kept revolving around Earth and formed Moon around 4.4 billion years ago. This is also supported by the fact that the chemical composition of Moon is similar to that of Earth.
Recent Findings of NASA and its implications: The Miniature Radio-Frequency (Mini-RF) detector of the NASA’s Lunar Reconnaissance Orbiter have recently found that the sub-surface of the Moon (2-5 kms) may have much higher concentration of metals (especially Iron and Titanium oxides) than what was previously thought.
This could mean that Moon may have been formed of material much deeper from the surface of Earth. Moreover, it indicates that Moon’s Molten surface cooled much more gradually.
Above findings clearly indicate that our understanding of the origin of Moon and its relationship with earth is incomplete and a lot of research still needs to happen in future.
