Hot take: If the Earth's core is Iron-Nickel, is it an Invar, and therefore, there's an effect too reduce earthquakes from expansion from heat movement being lower, or is the pressure alone enough to counteract that?
- 0xfae 3y agoThe core of the earth changes temperature very slowly. So any effect is probably pretty minimal. I would guess that comparatively huge thermal characteristics from the churning and moving of the crust and mantle due to plate tectonics probably overshadows this.
- pfdietz 3y agoThe core of the Earth is also far beyond the temperature/pressure at which this invar effect occurs.
