February 12, 2017 Weekly Geology Guess, Continental Drift

February 11, 2017
Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:

We will now venture into the realm of Plate Tectonics (old Continental Drift) compliments of Glenn.

>    There is a lot of material with this subject.

Continental drift is the movement of the Earth’s continents relative to each other, thus appearing to “drift” across the ocean bed.[2]

>    The fossil trail was the first piece of evidence for continental drift.

Actually Scrat the Paleolithic Squirrel chasing after his acorn is the cause of Continental Drift.

Sorry, I did not attach the usual video sites,  too much embedded Malicious Software.  R

>    Search:  Continental Drift, Plate Tectonics, North American Plate, Geology of Iceland.

I have attached pictures of Iceland from my wife’s visit, for your enjoyment.  No. 2 Son, James lives in Iceland.  Since Iceland is volcanic, it has numerous lava hot spots, hot springs, and geysers.  97% of the energy generated on Iceland comes from geothermal sources.  James works in a green house powered by geothermal energy.  These greenhouses are the size of football fields = Industrial Greenhouses.

“The geology of Iceland is unique and of particular interest to geologists. Iceland lies on the divergent boundary between the Eurasian plate and the North American plate. It also lies above a hotspot, the Iceland plume, which is believed to have caused the formation of Iceland itself, the island first appearing over the ocean surface about 16 to 18 million years ago.[1][2] The result is an island characterised by repeated volcanism and geothermal phenomena such as geysers.”  Wikipedia

>    As with most of my weekly fores into geology, with each topic I could write many papers and dissertations.

>    As usual, I scramble to just stay ahead of my audience.

Note:  I have intentionally reduced the amount of linked graphics in this email due to the amount of space required and trying to untangle everything the following week has been a mess.

Editors Note:  It is the intent of this site to keep this discussion as simple as possible, so as to educate the interested general public and not to discuss with the geology crowd the latest geologic theories and nuances.  Thanks, R

Next week, I will try and venture into Icelandic Geology since it is one of the few places on earth where one can see the plates tearing apart at the amazing speed of 1 inch per year (+2 cm/ year).


Enjoy the adventure!
