Question

Scientists believe the moon was formed

Answer 1

Answer:

The answer would be A) From the collision of protoplanet and proto-earth

Explanation:

The theory is that the Moon was formed when a Mars-sized object slammed into the Earth, billions of years ago. This collision turned the newly formed Earth into a molten ball of rock again, and ejected material into orbit. Most of the material crashed back into the Earth, but some collected together from mutual gravity to form the Moon. The planet never survived the collision, but we believe that large parts of that planet now form part of our Earth and of the Moon as well.

Answer 2

Answer:

a)From the collision of protoplanet and proto-earth

The isotopic homogeneity of this highly refractory element suggests that lunar material was derived from the proto-Earth mantle, an origin that could be explained by efficient impact ejection, by an exchange of material between the Earth’s magma ocean and the proto-lunar disk, or by fission from a rapidly rotating post-impact Earth.

However, it remains uncertain whether more refractory elements, such as titanium, show the same degree of isotope homogeneity as oxygen in the Earth–Moon system.

Scientists still believe the general idea of having an impact forming disk that coalesced into the Moon is probably right, but this paper shows that scientists still don’t fully understand exactly what the mechanisms were. There is a lot of exciting research still to be done in this field!
