Peer reviewedPratt, David – Journal of Scientific Exploration, 2000
Discusses the challenges confronting plate tectonics. Presents evidence that contradicts continental drift, seafloor spreading, and subduction. Reviews problems posed by vertical tectonic movements. (Contains 242 references.) (DDR)
Descriptors: Earth Science, Elementary Secondary Education, Oceanography, Physical Geography
Weisburd, Stefi – Science News, 1986
Reviews current ideas and research findings related to the flow patterns of mantle rocks. Highlights the components of the two-layer convection and whole-mantle models of mantle flow. Proposes that mantle flow is the key to understanding how the earth has cooled and chemically evolved. (ML)
