In A Geologist Looks at Noah's Flood, Dr. John Morris discusses the Genesis Flood from the viewpoint of a geologist. What evidence should a geologist expect to find of a worldwide flood? How does a geologist answer some of the common questions regarding a worldwide flood? Then Dr Morris examines the evidence that has been found.
Video Outline
I. General information about the flood
A. Predictions of a global flood
1. Rock and fossil deposition
2. Interpreting the rocks and fossils
a.
To a large extent, assumptions dictate interpretations and convictions
b.
Darwin's assumptions at Santa Cruz led to his extrapolation in biology
B. History of the Biblical flood - physical processes (Gen. 7:11,12)
1.
Fountains of the great deep broke open (earthquakes, tsunami)
2.
Windows of heaven opened
3.
Rained 40 days and 40 nights
C. Questions
1.
How was sufficient water to cause a global flood that covered the mountains?
a.
The oceans cover over 2/3 of the globe. The oceans are deeper than the continents are high. The highest mountain is less than half as high as the deepest ocean is deep. There is plenty of water to cover the globe.
b.
The modern mountains were not the ones that had to be covered by the flood. Mountains were probably not as high then. The flood laid down today's mountains. All major mountain chains are sedimentary rock that has been raised up.
2.
Where did the water go?
Into oceansmade deeper and wider
a.
Continents may have split apart
b.
Lighter continent rock rose in relation to denser oceanic rock. (Isostasyforces elevating land masses balance the forces depressing land masses.)
D. Flood predictions based on Scripture
1. Catastrophic deposition of sedimentary layers
2. Regional stratigraphy (opposed to local)
3. Large-scale erosion
4. Intense volcanism
5. Post-flood readjustment
II. Evidence for a global flood
A. Catastrophic deposition
1. Fossils
a.
Must be buried rapidly, or will decay
b.
Most are found as broken pieces, strewn together
c.
Interpretation of the geologic column (shows ecological zones, not evolution)
2. Turbidites
a. Definition b. Look exactly like deposits in Appalachian Mountains
3. Mt. St. Helens
a. 600 ft. deposited in days b. Finely laminated layers
4. Boulders
a.
East San Diego County has layers of boulders, this requires a catastrophe
b.
Grand Canyon's lowest layer of tapeats sandstone has boulders.
c.
Boulders are found in the Basal Conglomerate (the bottom layer of the Cambrian System), which is what you would expect if the Flood occurred.
B. Regional stratigraphy
1.
Widespread coal beds
2.
Widespread sandstone beds (U. S. and Canada); similar to beach sand
3.
Tapeats sandstone in Grand Canyon, Chicago, and Pennsylvania
C. Large-scale erosion
1. Underfit rivers (ex: Grand Canyon)
2. Meandering rivers
D. Intense volcanism
1. Volcanoes
2. Mountain uplift
E. Post-flood readjustments
It took several hundred to a thousand years before the earth settled back to equilibrium like it has today.
1.
Earthquakes
2.
Volcanoes
