One idea used to dispute the theory of plate tectonics is the concept of "geosynclines," which posits that geological features such as mountain ranges and ocean basins are formed by vertical movements of the Earth's crust rather than horizontal movements of tectonic plates. Critics also argue that some geological features can be explained through alternative mechanisms, such as thermal contraction or the Earth's cooling process, rather than plate interactions. Additionally, some geologists suggest that the fossil record and the distribution of certain species do not consistently support the movement of continents as proposed by plate tectonics. However, these alternative theories have largely been overshadowed by the overwhelming evidence supporting plate tectonics.
One argument used to dispute the theory of plate tectonics was the lack of a mechanism to explain how the continents could move across the Earth's surface. Critics questioned how large landmasses could drift without a physical force or process to drive their movement. Additionally, some geological features, such as mountain ranges and oceanic trenches, were thought to be formed by static processes rather than dynamic tectonic activity. However, advancements in the understanding of mantle convection and seafloor spreading eventually provided compelling evidence supporting plate tectonics.
Plate tectonics is the theory used to explain the structure of the Earth's various formations and plate boundaries between the major tectonic plates.
One key idea that promoted the theory of plate tectonics was the concept of continental drift, originally proposed by Alfred Wegener in the early 20th century. He suggested that continents were once joined in a single landmass and have since drifted apart. Evidence supporting this theory included the matching geological formations and fossil distributions across continents, as well as the fit of the coastlines. The development of seafloor spreading in the 1960s further solidified the theory by explaining the mechanisms behind plate movement.
The plate tectonics theory is not relevant to the formation of the Hawaiian Islands, but the theory explains why the islands formed in a chain. According to the theory, the plates move constantly. This caused the islands to form in a chain, as the hot spot under them does not move.
The existance of land bridges between continents
The existance of land bridges between continents
An argument that was used to dispute the theory of plate tectonics was the Land Bridge Theory. Land Bridge Theory held that shifting portions of dry land explained the finding of identical species on different continents. Plate Tectonic Theory gradually gained favor and eventually eliminated the Land Bridge Theory.
Continents cannot cut through the ocean floor.
One idea that was used to dispute the theory of plate tectonics was the belief in fixed continents. Some scientists thought that continents were stationary and did not move, which was contrary to the idea that they were drifting on the Earth's surface.
A proposed explanation for identical species found in divergent locations was the land bridge theory, which supposed shifting dry areas across which living things spread. The further study of rock formations (which were also identical) lent greater weight to the idea that continents were actually joined together in the past.

One idea used to promote the theory of plate tectonics was the discovery of matching coastlines and geological features on opposite sides of the Atlantic Ocean, known as "continental drift." This supported the idea that continents were once connected and had drifted apart over time due to the movement of tectonic plates.
The idea of seafloor spreading, proposed by Harry Hess in the early 1960s, helped promote the theory of plate tectonics. This idea explained how new oceanic crust is formed at mid-ocean ridges and then spreads out, pushing older crust aside. This process provided a mechanism for how continents move and gave strong evidence for the movement of tectonic plates.
