Wouldn't erosion cause sea levels to rise?
Can anyone access this:
Another Important Factor of Rising Sea Level: Soil Erosion - Zhang - 2012 - CLEAN – Soil, Air, Water - Wiley Online Library ? I searched Google for "how much does erosion increase sea levels?" and that was the only article that I found that did not claim that George W-made global warming was causing the sea level to rise, which was causing erosion. I am not saying it is not, but isn't there natural erosion? Rainfall and waves on beaches? I was putting my full energy into studying for the GRE and I remembered that Chris Isaak went to reshoot some footage for "Wicked Game," but the beach had eroded. Apparent confirmation (but nothing worth quoting): https://www.e-education.psu.edu/earth107/node/886 Oh right. I need to study! |
Or a 8 magnitude earth quake that cases the sea floor to raise nearly 100ft.
Since the earth's gravity and force or rotation will actually cause the sea level to rise faster in the middle of the Pacific more than anything. Depending on how the added water acts it may cause sea levels to briefly decline. |
The increase in the sea level is what causes the extra erosion.

It says that you personally have caused the sea level to rise several inches in the past century. So what? What difference does that make? You still have rain and waves causing erosion. So, maybe it is eroding sand and soil a bit higher. This does not change the fact that rain and waves cause erosion and erosion causes the sea level to rise. I shared a source supporting my argument. Are you going to find one saying there is not any natural erosion? |

Yeah... as land erodes, it gets lighter, and should rise above the general level of the ocean.
This is what's been happening in many northern latitudes, as the land is *still* rebounding due to the retreat of glaciers from the last ice age. |
Mountain ranges and land ice have "extra" gravity that has a very large effect on sea level. Antarctica has so much ice, it pushes the land down almost 1/2 mile, and the sea level south of the equator is something like 8,000+ feet higher. The oblate spheroid of our planet (because of it rotating on its axis) is "sagging" southward. Here's an article that explains it:
https://www.npr.org/templates/story/...toryId=9428163 Because water expands as it warms, this spreads it out over a greater area, so the mass on any given spot is slightly less. |
