Why haven't seafloor mountains eroded into nothing with

Well, with depth in the water, the rate of erosion would decrease significantly because of lack of overall movement. Usually only the upper layers of the water are effected by currents and winds, while the lower layers aren't. Then you have precipitation and mass wasting events on the upper parts of the Islands which erodes Islands pretty rapidly in terms of geological time.

Mass wasting still occurs underwater with sea slumps and whatnot over time, you can see a lot of evidence of this in places like Hawaii and coastlines in general such as the west coast of NA.

So yes they are eroding slowly over time, just slower than the rates of erosion on the upper surfaces, which is why volcanic Islands after their volcanism ends simply erode away into coral atolls, in which the volcano has completely eroded away, leaving its fringe reefs behind which can keep up with the erosion / sea level rise due to limestone secretion and vertical movement upwards by the reefs.

The first law of thermodynamics. Erode just means to wash away. It's not disappearing faggot.

This.

This is /sci/ not a place to discuss your doctoral thesis. Jesus christ

Thanks bud.

Why are geologists always the ones that make the best posts?

>>8538726
Every natural fenomena is quite interesting.

>>8538726
Because dinosaurs are cool, and palaeontologists study dinosaurs, and palaeontologists are geologists, so geologists are cool.
