Holmes' theory of mantle convection proposes that the Earth's lithosphere is broken into tectonic plates that move over the asthenosphere due to the circulation of molten rock. This movement is driven by the heat generated in the Earth's interior, causing the plates to collide, diverge, or slide past each other, leading to geological phenomena like earthquakes and volcanic activity.

What was Arthur Holmes' theory of continental drift?
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.
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.
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.
When was Arthur Holmes' theory proved?
Arthur Holmes' theory of plate tectonics was not proven by a single event or discovery. Instead, it was gradually accepted as more evidence from seafloor spreading, magnetic anomalies, earthquakes, and volcanic activity supported the theory. Holmes' work laid the foundation for the development of the modern theory of plate tectonics.
Was Arthur Holmes a geologist?
Yes, Arthur Holmes was a prominent geologist known for his work on radioactive dating and mantle convection. His research laid the groundwork for understanding Earth's deep structure and the concept of plate tectonics.
What was Arthur Holmes' theory?
Arthur Holmes theory was that the mantle under goes thermal convection.
What was Arthur Holmes 1928 theory?
Arthur Holmes 1928 theory described plate tectonics and a modern view of the solid Earth. He pioneered the use of radioactive dating of minerals, and understood the mechanical and thermal implications of mantle convection, which was a basis for plate tectonics.

Whose idea later assisted in the recognition of wegener's theory?
Arthur Holmes's idea of mantle convection helped provide a mechanism for plate tectonics, which later supported the recognition of Wegener's theory of continental drift. Holmes's work contributed to advancing the understanding of Earth's geology and the movement of continents.
What is the scientist who first proposed that thermal convection in the mantle causes continental drift?
Arthur Holmes
Who came up with the theory of plates tectonics?
J.T Wilson was the one who came up with the theory of plate tectonics. Harry Hess came up with the theory of sea-floor spreading. Alfred Wegener came up with the theory of continental drift and Arthur Holmes proposed a suitable mechanism for this to occur (mantle convection).
Who is the scientist who first proposed that thermal convection in the mantle causes continental drift?
Alfred Wegener, a German meteorologist and geophysicist, proposed the theory of continental drift in 1912. He suggested that thermal convection currents in the mantle cause the movement of continents over time.
Who was the first scientist who proposed that that thermal convection causes continental drift?
Arthur Holmes

Who modernly states the theory of Pangaea?
Arthur Holmes i believe.
