The statements below are all true. Some of them represent important reasons why the giant impact hypothesis for the Moon’s formation is taken seriously, and some of them are not relevant to deciding between this and other hypotheses. Sort the statements into the correct bin according to whether or not they provide important support to the giant impact hypothesis.-Moon's composition is similar to Earth's mantle-Moon has a low proportion of easily vaporized ingredients-Models indicate early solar system had Mars-size leftover planetesimals

Relevant statements -

Moon's composition is similar to Earth's mantle

Moon has a low proportion of easily vaporized ingredients

Irrelevant statements

Models indicate early solar system had Mars-size leftover planetesimals

Explanation:

The giant impact hypothesis basically states that the moon was formed from a direct collusion of the planet's earth and mars.

Evidence for this hypothesis includes:

(1) The Earth's spin on its axis and the Moon's orbit have similar orientations and movement patterns.

(2) Samples from the moon indicate that the Moon's surface was once molten.

(3) The Moon has a relatively small iron core which is similar to the Earth`s core.

(4) There is evidence in other solar systems of similar collisions.

(5) Giant collisions are consistent with leading theories of the formation of the Solar System.

(6) The material that formed the Moon originated from the outer layers of Earth rather than from its core. This is why the moon is naturally devoid of iron.

(7) A giant impact that struck the earth in an indirect way- by the side (not a direct impact) could also account for Earth’s rapid initial spin. (8) The impact of the said collusion would vaporize a substantial portion of surface material which would account for the Moon's lack of volatile materials.

(9) The stable-isotope ratios of the moon and the earth's terrestrial rock are identical, implying a common origin.

The first two statements are part of the evidences that support the great collusion theory making them relevant. However, the last statement - Models indicate early solar system had Mars-size leftover planetesimals - has no connection with the giant collusion theory so it is irrelevant.
