Arthur Holmes was a strong advocate of Alfred Wegener's theory of continental drift at a time when it was considered very controversial as there was no known mechanism which could allow this to occur.
Holmes proposed that there was mantle convection allowing dissipation of heat from the core and that these convection cells could be a driving force of continental drift. This theory was ultimately incorporated into the modern understanding of sea floor spreading that occurs at mid-ocean-ridges.

RafaArthur Holmes proposed the theory of mantle convection in the early 20th century, suggesting that heat-driven movement of material in the Earth's mantle could cause the crust to move. This laid the groundwork for the modern understanding of plate tectonics, a theory that explains the movement of Earth's lithosphere, including continental drift. Holmes' work helped to revolutionize the field of geology.

What theory replaced Wegener's hypothesis of continental drift?
I think that continetal drift replaced his theory
Scientist who first proposed that thermal convection in the mantle causes continental drift?
Alfred Wegener, a German meteorologist and geophysicist, first proposed the theory of continental drift in 1912. He suggested that the continents were once part of a single supercontinent called Pangaea, which later broke apart and drifted to their current positions due to the movement of the Earth's mantle caused by thermal convection.
What was the continental drift theory replaced by in 1967?
The continental drift theory was replaced by the theory of plate tectonics.
What are two things that support the continental drift theory?
Two things that supports the continental drift theory are; 1. Fossil. 2. Continent Shapes.
Whose ideas later assisted in the recognition if Wegener's theory?
Arthur Holmes's ideas in the 1920s about mantle convection and radioactive heating helped support Alfred Wegener's theory of continental drift by providing a mechanism for how the continents could move. This helped pave the way for the eventual acceptance of Wegener's ideas as the theory of plate tectonics.
