theory that explains how continents reached their current place
Pangaea probably?
Spreading Of ocean floor
The Super Continent was broken apart, in part by sea-floor spreading.Scientists discovered that sea-floor spreading continues to move the continents.Sea-floor spreading can be measured using specialized equipment.
One aspect not included in the support for Harry Hess's hypothesis of sea floor spreading was the lack of direct evidence of the mechanisms driving the process, such as mantle convection. Additionally, the age and magnetic anomalies of the ocean floor were not fully understood at the time, which limited the initial acceptance of his ideas. Furthermore, the concept of plate tectonics, which later provided a comprehensive framework for understanding sea floor spreading, was not yet developed during Hess's proposal in the early 1960s.

"Magnetic Polarity: the North and South magnetic poles have switched positions throughout Earth's history... the record of magnetic polarity in the rocks of the ocean floor provided unequivical support for the seafloor spreading hypothesis." - as quoted in chp. 4, pg. 94, from the textbook "The Good Earth: Introduction To Earth Science"

Sea floor spreading occurs at the mid ocean ridges.

Sea floor spreading occurs at mid-ocean ridges
The discovery of mid-ocean ridges, where new oceanic crust is formed, supported the theory of sea-floor spreading. The mapping of magnetic stripes on the ocean floor, showing alternating patterns of magnetic polarity, provided further evidence for sea-floor spreading. The age of the oceanic crust getting progressively younger away from the mid-ocean ridges supported the concept of sea-floor spreading.
