Thread: Oceanic strectch marks (??)

While looking at the oceans (using Google Maps - Earth) I notice some kind on straight lines running under the oceans and between the continental plates. They look like strecth marks and I can see this phenomena all over the oceans planet. They do not seem to continue above sea level. The funny part is that they tend to run straight and turn in sharp angles, forming polygonial shapes under the ocean. My immediate assumption was the earth's mantle pushing up from below the continental plates. But, what puzzles me is the way this process seems to operate (creating straight (not jagged) lines that run for thousand of miles). Can anybody add more lights as to what they are? and why they form in such an unexpected manner?

They are most likely imaging artefacts and do not exist in reality. Unless you mean something else, in which case could you take a screenshot and post it on here and we can have a better look.

If they are very, very straight lines, then they're probably an artefact of satellite imaging.

Most other almost straight lines are just "landscape" features of the sea floor. The sea floor is just like dry land but under varying depths of water. Though a lot of those line type features resemble lines of sand dunes. The parts of the sandy sea floor can be affected by flowing water currents in much the same way as desert sand dunes are affected by flowing winds.

Thanks Pioko for responding. I could not cut/paste a screenshot from Google Earth. If you have a chance, could you please browse the site (Google Maps - Earth). Look for a section East of Clipperton Island. That is a good example of the "strecth marks" I refer to. Sorry for any inconveniences.

Thanks Adelady for responding. Pioko also suggested those lines could be the result of satellite imaging. Is there a way to corroborate that for sure?

Yes, they are imaging artefacts.

Thanks!

In some Google Earth images if you zoom into a river etc (try the Amazon River) you can see things that look like computer chips. All compression and/ or imaging artefacts.

edit: Although Google replaces images every 4 years or so, and improves them.

I saw it. Those "seamed" areas on the Amazon river can be observed when zoomed to a 10 mile-mark. Those under the ocean, can be observed even at a 100 mile-mark. I sent a feed back to Google Earth about this issue. Thanks again for your feed back and hope to continue sharing thoughts with you in future forums (or fora). Good Night.
