Summary: God teaches Noah and us patience in times of trouble.
I came up to my computer yesterday and it said "the operating system has experienced a serious error." After rebooting - the system returned itself to normal and on I went.
In a sense, earth experienced a "serious error" that caused God to "reboot" and recover with the flood. The account in Genesis 8 (quickview)  begins this "rebooting" of the creation. Some of the language mirrors what we find in Genesis 1 (quickview)  (turn and read).
Last time we looked at an unusual chart that seeks to show how the flood was responsible for much of the geological upheaval that most scientists attribute to long epochs of time.
Beginning in Chapter 8 we have the end of that table:
150th Day: A wind passes over the earth. Waters begin to subside. Ark lands on the mountains of Ararat. (Gen 8:1-4) Continental-Drift Phase: Mid-Atlantic Ridge buckles up; Atlantic floor rises and Pacific region subsides, so the hydroplates accelerate downhill, sliding on a layer of lubricating water.
When the massive hydroplates decelerate, they are crushed, thickened, buckled, and heated in a gigantic compression event. Overthrusting occurs in some places. Continents take on present shape. As major mountains form, air is displaced, causing a great wind. Earth rolls, and poles shift.
150th - 371st Day: Passengers remain on Ark. Recovery Phase: Hostile environment: earthquakes, inner earth heated, oceanic trenches and methane hydrates form, flood basalts and volcanoes erupt, water drains, continents shift, vegetation reestablished, and Ice Age begins. Lowered sea level facilitates land migration and allows the formation of tablemounts and submarine canyons. Plateaus form. Large continental canyons form by dam breaching.
371st Day: Ark off-loaded. (Gen 8:15-19)
371st Day to the present.
Noah and the animals spent just over a year on the ark.
Mt. Ararat are located in Lake Van region of eastern Turkey in the area of Armenia. The highest peak in the range reaches some 17,000 feet in elevation. There are really two peaks: One is 16,254 feet and the other is 12,000 feet.
Notice that Noah was safe in the ark - but he wasn’t delivered yet from the flood. God was doing a lot in the background - unseen by Noah - to secure his deliverance. Noah’s job was to wait patiently. That’s what we should do too.
Isaiah 40:31 (quickview)  But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint. KJV
God remembered Noah - He keeps his covenants.
Verses 6 - 12
The Raven & the dove. The raven could have landed on mountaintops and carcasses to rest or get food. The dove returned with a fresh olive leaf - olive trees will put out new leaves even under water. This showed that the tops of trees were emerging.
Ravens will eat carrion - dead things, so they could have landed on stuff floating around and been okay.
Verses 13 - 14
On Noah’s 601st birthday he gave himself a present - he took off the roof of the ark and looked around - and saw the water was gone. But though he could look around at the situation, it was only God that could open the door.
