Mantle plumes are distributed around the core in a known pattern.
the verdict
SUPPORTED
the evidence backs this
confidence 75/100
Mantle plumes originate from organized deep-mantle structures such as large low-velocity provinces at the core-mantle boundary, indicating they are distributed in patterned rather than random locations.
