There might be fewer rabbits and foxes
Actually, large drops of rain form in a cumulonimbus cloud are stated by water vapor condensing in large quantity. If the humidity is very high, or around 100%, water droplets will form extra large during the condensation process. Additionally, this increases the size of the cloud. The droplets will amalgamate to form even larger rain drops that fall because of gravity. I hope this helps! :))
Ps. Cumulonimbus clouds also produce hail, but that hail is not the reason for why they produce big rain drops.
Answer:
A reaction that joins the nuclei of two atoms into one
Explanation:
Think of the words "nuclear fusion".
Nuclear = "relating to a nucleus"
Fusion = "joining"
So, nuclear fusion is the joining of two nuclei into one.
A and B are wrong, because chemical reactions involve electrons.
D is wrong, because the splitting of a nucleus is fission.
