Iceland, Where Europe And North America Meet.

There is vast ocean separating North America from Europe. There would be no way that Europe and North America could meet, not with land masses touching.

However, if you go to the Mid-Atlantic Ridge, there is something else to be found. A divergent plate boundary in the middle of the Atlantic Ocean is where the North American and Eurasian Plates meet. In the country of Iceland, this is known as Reykjanes Ridge. The Mid-Atlantic Ridge goes through Iceland.

One major feature is the Silfra Fissure. A rift formed by the Mid Atlantic Ridge. This is a divergent plate boundary. The plates are moving away from each other.

Taking a dive into the spring-fed waters of the Silfra Fissure will bring a point home. At this point, a diver can touch both the North American and Eurasian plates at once.

The Mid-Atlantic Ridge also plays a role in Iceland’s geothermal power resources. Being a geothermal hotspot, this helps Iceland.

Iceland is located closer to continental Europe than continental North America. However, it is on both the North American and Eurasian plates. It also has some proximity to Greenland, a large North American island ruled indirectly by an EU nation, Denmark. It its own way, Iceland can be considered where Europe and North America meet.

 

Shells, Now And Later

shellsIf one ever goes to the beach, one can find many shells. This is assuming that said persons are looking for shells. Shells can be found in other places such as rivers and lakes. Anywhere a mollusk can inhabit, so can shells be found. However, there is more.

Fossils of shells have been found in many places. Fossils tell alot about what kinds of animals and plants existed in the past. Sit and thing about this. One can kind shells. Those shells were not there by accident. Someone once lived in that shell. Either the animal left that shell, or it was extracted from that shell. The shells that we see today could be the fossils some scientists find thousands of years from now. The earth’s physical processes can turn today’s shells into fossils. Think about the fossils we find today. They were once living things a long time ago.

All of that is in the future. However, looking towards the future is important in the earth sciences. This in addition to looking at the past and at today.

Railroads and Geology

If you go to some railroad tracks, look at the rocks. Many do not understand that there is a connection here between geology and railroads. Here is a lesson in geotechnics.

In a nutshell, the layer of rocks, known as track ballast, is like a foundation for the tracks, stopper of flooding, inhibitor of weeds. To get a more detailed explanation of this topic, watch the video below.
