How are magnetic stripes near mid-ocean ridges evidence for sea-floor
spreading?


plz help me with one or the other.

Answer 1

Sea floor spreading has been documented based on the magnetic stripes matching opposite sides of the spread. The rocks go

w-x-y-z-spread midpoint-z-y-x-w

The magnetic stripes are based on iron and other magnetic elements in the rock aligning the same way. Also composition of the igneous rock matches up. The magnetic poles shift slightly over great periods of time and the rock in the stripes vary slightly as they were created.

Answer 2

i think that the item is the two a hoax or the guy is an fool and not in any respect a geologist except he replaced into experienced until now the Nineteen Sixties and stored his head firmly the place the sunlight does not shine. The data for plate tectonics is elementary. it truly isn't any longer a rely of consensus. it truly is like thinking if glaciers flow or vegetation strengthen. it truly is measureable. only the magnetic anomalies on my own furnish an open and close case for sea floor spreading. There might desire to nevertheless be issues unknown approximately plate tectonics, which comprise how the plates behave decrease than particular circumstances however the actual undeniable fact that plates migrate around the planet isn't controversial, no longer credibly besides. Plate tectonics is an theory with various data to assist it. It has probable moved previous an theory. important or volatile human led to warming isn't something yet junk technological information.

Answer 3
