The Sun is about:
The mean distance between the sun and the earth is 149,598,000 km. In terms of light years, it is 8.311 minutes of a year.
The terrestrial planets were formed in the close vicinity of the
The terrestrial planets were formed in the close vicinity of the parent star where it was too warm for gases to condense to solid particles. Jovian planets were formed at quite a distant location.
Firstly life on the earth was originated in
Firstly life on the earth was originated in oceans. Ocean began to have the contribution of oxygen through the process of photosynthesis.
Big-Bang theory was postulated by

Water vapours and gases in the atmosphere were contributed by
Continuous volcanic eruptions contributed water vapour and gases to the atmosphere. As the earth cooled, the water vapour released and started getting condensed. The carbon dioxide in the atmosphere got dissolved in rainwater and the temperature further decreased.
The oceans were formed within_________from the formation of the earth.
The earth’s oceans were formed within 500 million years from the formation of the earth. This tells us that the oceans are as old as 4,000 million years.
Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. Fossils vary in size from microscopic, such as single bacterial cells only one micrometer in diameter, to gigantic, such as dinosaurs and trees many meters long and weighing many tons.
Expansion of universe means
The distance between the galaxies is found to be increasing and thereby, the universe is considered to be expanding.
