Earth’s geology has gone through many changes since the beginning in Genesis 1:1. Earth started out as a planet covered with water Genesis 1:2, to a planet now that is covered with 70 percent water and 30 percent dry land. The changes in the Earth’s geology has not been gradual over a long period of time but very catastrophic in a very short time. Just look how devastating volcanic eruptions are on the Earth today. They change the surface of the Earth in very short time.
There was something so devastating that the marks of it are still seen on the Earth today. This event only took a year to change the face of the Earth forever. It was the worldwide Flood of Noah’s day (Genesis 6-8). The Flood started when God broke open the fountains of the great deep and opened the windows of heaven (Genesis 7:11). The great fountains that burst open brought a large amount of water to the surface and shot water and rock debris high into the atmosphere of Earth. Some water and rock debris escaped into space, But a lot of it came back to earth as rain causing torrential rain storms all over the planet Earth.
According to the Biblical record, it was because of the utterly and hopelessly wicked condition into which the earth’s original peoples had degenerated that God sent a cataclysmic Deluge to “destroy with the earth” (Genesis 6:13). This event is described in detail in Genesis 6 through 9 and is referred to many times in other parts of the Bible and by Jesus Christ Himself. It is also recorded, in more or less distorted and incomplete fashion, in the legends of hundreds of cultures all over the world.
According to the Apostle Peter, “the world that then was being overflowed with water, perished” (II Peter 3:6). As described in the Bible the Flood waters battered the entire globe for a year and were immensely destructive in effect. All of the processes of sedimentation, volcanic eruptions, tectonism, fossilization, and other geologic and weather conditions, were extremely active during this period. No true scheme of historical geology could possibly be erected without full consideration of the tremendous geologic records that must necessarily have been inscribed in the earth’s crust by this awesome event . Geologists often attribute specific geologic deposits to local floods. A global flood in a very short time would have immense geological records everywhere. This can be seen today. Just take a good look at the Grand Canyon in Arizona.
The Biblical record says that it began when, in one day “were all the fountains of the great deep broken up.and the windows of heaven were opened” (Genesis 7:11), and that this continued for 150 days before “the waters assuaged” (meaning started to recede from the land) so that the Ark could come to rest “on the mountains of Ararat” (Genesis 8;4). God let everybody out the Ark when the land was completely dry (Genesis 8:13-19).
