It most suppoet tge impact theory.

Explanation:

The his impact theory or the big splash is one of the accepted theories of tge moon and it states that the moon or luna and explain the origin of the moon that a Mars sized object planetestimal collided with the the proto Earth and the ejecta debris joined together by gravitational force which is the moon and it's orbit the Earth. The moon have similar composition to the outer portion of the Earth.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
