Explanation:
The early Precambrian era began 4.6 billion years ago. The formation of eath start from this era with dust and gas. The atmosphere at that time was too hot. It was like hades. The rocks were molten and appear to like an ocean of rocks.
Due to the molten rocks, there are no samples of rock from this area as it was too hot to be formed. There were boiling sulfur and gases were everywhere.
Carbon forms the key component for all known life on Earth. Carbon is the basis of all molecules. Its is easily able to bond because of the 4 valence electrons.
Because wind is a source of energy which is non-polluting and renewable , is he turbines create power without using fossil fuels. Hope this helps!
