In 1912, German meteorologist Alfred Wegener published his groundbreaking theory of continental displacement. His theory proposed that the continents were once a single land mass but had slowly moved apart over millions of years. This fascinating book examines the scientific process behind Wegener's theory and how it challenged prevailing views of the time. Readers will discover how years after Wegener's death his theory was embraced by scientists and is now the basis for modern earth science.
