Answer 2

Answer:

• Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula.
• Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.

Explanation:

• They were made of the leftover gas from the nebula that made the Sun.
• The Moon may have been formed after a collision between the early Earth and a smaller planet (sometimes called Theia).
• Much of Earth's water is thought to have come from asteroids impacting the planet early in its history.
• The surface of the very young Earth was initially an ocean of magma.
• Hydrogen and noble gases from the solar nebula were drawn to the planetary embryo, forming the first atmosphere.
