Alfred Wegener was a German scientist and geophysicist who is best known for his theory of continental drift. He was born on November 1, 1880, in Berlin, Germany, and died on November 1, 1930, during an expedition in Greenland.

Wegener’s theory of continental drift proposed that the continents were once joined together in a single supercontinent called Pangaea and have since drifted apart over millions of years. He supported his theory with evidence from fossil records, geological formations, and similarities in rock types and mountain ranges across different continents.

However, Wegener’s theory was met with skepticism and criticism from the scientific community during his lifetime. It was not until the 1960s, after further evidence was discovered, that his theory was widely accepted and became the foundation for the modern theory of plate tectonics.

In addition to his work on continental drift, Wegener also made significant contributions to meteorology and polar research. He participated in several expeditions to Greenland and conducted research on weather patterns and climate change.

Alfred Wegener’s work laid the groundwork for our understanding of the dynamic nature of Earth’s continents and the processes that shape our planet’s surface. He is considered one of the pioneers of modern geology and his theory of continental drift revolutionized the field of earth sciences.
