Which one of the following refers to 'the Big Splat'?

Result
Your answer: —  ·  Correct: A

Explanation

The term 'Big Splat' refers to the Giant Impact Hypothesis, which is the leading scientific theory for the formation of the Moon. According to this hypothesis, approximately 4.5 billion years ago, a Mars-sized celestial body (often called Theia) collided with the proto-Earth. The impact was so energetic that it ejected a massive amount of debris from the Earth's mantle into orbit. This material eventually accreted to form the Moon. This event explains why the Moon has a similar isotopic composition to Earth's mantle but lacks a large iron core. In contrast, the 'Big Bang' refers to the origin of the Universe (Option D), while the formation of the Sun (Option C) and Earth (Option B) occurred through the collapse of a solar nebula and planetary accretion respectively.
