Scrolling Aroung Google Earth This Morning...

 

  Interesting underwater geology between NA and SA and SA and Antarctica.

Just interesting that's all.

  1. I think those, what appear to be trenches in the ocean, are subduction zones between plates.

  3. Great places to hide, if you can do it.

  4. Could be scar tissue from an asteroid impact.

  5. That dark area north of Puerto Rico is the Puerto Rico trench. It's the deepest spot in the Atlantic ocean at over 27,000 feet deep. Two tectonic plates moving in opposite directions.

  6. As opposed to Teutonic plates which separate Germany from Poland.

  7. Go check out The Sigsbee Deep in the Gulf of Mexico down southeast of Brownsville. https://en.wikipedia.org/wiki/Sigsbee_Deep
    The depth is disputed but there have been measurments taken that show it as much as 17,000 feet deep.

  8. The two areas almost look like they were scooped out, or pushed out by somthing.

    1. Thats funny, looks like a flow pattern, from currents of liquid or solid dragging or pushing respectively, under the more solid mantel, like currents of magma below, and after periods of time this pattern appears above, from friction/drag effects? It would have to form over relatively long geological time frame. But that there's similarity between the forms and their location between the tips of large land mass suggest something similar going on.

  9. Underwater mountain ranges moving with plate tectonics

  11. Funny isnt it, All these ancient problem solving asteroids craters from history. BUT, When you WANT a asteroid to come in, you cant find one anywhere. Where the freak is ours!!!

  12. Recommend you check out Dutchsinse on YouTube. His live shows are on Twitch but he publishes them to YT afterward. He talk all about those areas and more.

  13. The curved string of islands that runs roughly from the eastern tip of Puerto Rico to Venezuela is volcanic. (Windward and Leeward Islands) There are at least 3 active volcanoes. One on Montserrat which exploded in 1995 destroying a lot of infrastructure, and killing a lot of people, and there is also an active volcano on Martinique. There is one undersea volcano which is (or was) marked on charts as an exclusion zone. Gas releases destroy buoyancy and can cause vessels to sink. I believe it is just north of Grenada, but I haven't looked at charts of that area in decades.
