Final answer:
Wegener's Theory is connected to the concept of continental drift, where Wegener proposed that the continents were once part of a supercontinent called Pangaea and have since drifted apart. His theory laid the foundation for modern plate tectonics.
Step-by-step explanation:
The theory associated with the concept of continental drift is b) Wegener's Theory. Alfred Wegener, a German scientist, proposed the scientific theory for the slow shifting of the continents which he termed as 'continental drift'. He suggested that the continents once formed a supercontinent named Pangaea and have since drifted apart. Wegener's hypothesis was based on various pieces of evidence, including the jigsaw-like fit of the continents, fossil similarities across oceans, and paleoclimatic data. Although it was initially met with skepticism, Wegener's idea laid the groundwork for the modern theory of plate tectonics.
Wegener's pioneering contributions, including his hypothesis of continental drift, provided fundamental insights into Earth's geological history. Despite the lack of a mechanism to explain the drift during his time, his concept greatly influenced subsequent geological theories and research. Wegener's work is an essential component in the field of geology and earth sciences.
