1 And the Lord said unto Noah, Come thou and all thy house into the ark; for thee have I seen righteous before me in this generation.
2 Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female.
3 Of fowls also of the air by sevens, the male and the female; to keep seed alive upon the face of all the earth.
4 For yet seven days, and I will cause it to rain upon the earth forty days and forty nights; and every living substance that I have made will I destroy from off the face of the earth.
5 And Noah did according unto all that the Lord commanded him…
10 And it came to pass after seven days, that the waters of the flood were upon the earth.
11 In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.
12 And the rain was upon the earth forty days and forty nights.

JGL Comment: The fragmented arid and tropical areas on the earth today I do not think were present prior to the Flood. The destruction from floods were not present before the Flood. Patchy rain was not present. Frigid snow falls were not present. Scorching heats were not present. We are living in a post Noah Flood environment.
