Where do supporters of the outside-in model say earth’s water originated from? inside of volcanoes inside the atmosphere bonded to meteorites that hit the earth bonded to minerals in earth's mantle

Bonded to meteorites that hit the Earth

Explanation:

Some hypothesis refering to origin of water on Earth sugges, that a very long time ago as asolar system was young, some asteroids may have landed also carrying frozen water. The meteorites would then turn to provide liquid water, these meteorites were protoplanets from the outer asteroid belt that is in the solar system.

However this still is not the mainstream theory.

the answer is b)3/8x+1

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
