<span style="font-weight:600; color:#0000ff;">[...]</span> gathered evidence in support of his idea that the continents were once together in a supercontinent that later broke apart | <span style="font-weight:600; color:#0000ff;">Alfred Wegener</span> gathered evidence in support of his idea that the continents were once together in a supercontinent that later broke apart |
Although Wegener's idea was convincing, the scientific community at the time rejected it because he could not explain <span style="font-weight:600; color:#0000ff;">[...]</span> | Although Wegener's idea was convincing, the scientific community at the time rejected it because he could not explain <span style="font-weight:600; color:#0000ff;">how the continents moved</span> |
Wegener and his idea began the long road to plate tectonic theory that took a half <span style="font-weight:600; color:#0000ff;">[...]</span>. | Wegener and his idea began the long road to plate tectonic theory that took a half <span style="font-weight:600; color:#0000ff;">century</span>. |
