That would depend upon where it was raining (the whole Earth or less than that), and how powerfully. The atmosphere contains 37,500,000,000,000,000 gallons of water. Concerning Noah's Flood, we have to note that the water came from subterranean sources also, and that its covering of the mountains may not have occurred on the entire Earth simultaneously.

That's the way God destroyed the earth, besides Noah and his family, with two of every animal. And Jesus did fast for the same amount of time, and the Jews wandered for forty years in the desert during the Exodus from Egypt.
The rain lasted 40 days and 40 nights, according to Genesis 7:12 and 17]. But God didn't tell Noah in advance how long the rain would last. God just let Noah know that the rain would begin seven days after Noah and his passengers boarded the ark [7:4, 10].
For the water and the salt. We can learn from the salt of the ocean. The rivers would have a dead end and be a box and over flow when it rained and would flood.
The past tense of "rain" would be "rained".It rained is the past tense
If it rained 1 inch thick water over 1 square mile, the volume of that water would be approximately 2,323,200 cubic feet. That is equal to 65,785,698.28 kilograms, or 145,030,199 pounds.
If it rained continuously for several weeks, the water table would likely rise. The water from the rain would infiltrate the ground and saturate the soil, leading to an increase in groundwater levels. This could potentially result in flooding in low-lying areas.
Days are longer than nights in the summer, and the reverse in the winter.
sometimes the fish decay and disolve in the water. Also another reason would be because the fertilizers from the plants rin in the water after it had rained.
Then the world would have no days or nights. We would just be either day or night depending on when the earth stopped rotating on it axis.
If it rained over an Aztec home, the flat roof design would likely collect the water in channels and direct it to a cistern for storage and later use. The Aztecs were known for their advanced water management systems, so rainwater harvesting would have been an important part of their household infrastructure.
They used irrigation tunnels so when it rained or flooded the water would be caught and flow to the crops they also connected these tunnels to rivers near by
that would be helpful
