Free 5-day trial People used to think that Earth was static, and that it never changed.Gradually, a body of evidence was gathered that made no sense in this model.(Stepping-stone islands would be a series of islands that traversed the ocean.) Wegener developed a much simpler hypothesis that stated perhaps the continents were all together at one point, thereby also explaining the fit of the coastline.He then theorized a supercontinent he named Pangea, which meant 'one earth'.The Story of Coal (Hi/Lo Grades 2-3) Stress and Strain in the Life of a Rock (Hi/Lo Grades 3-5) Resources from the Land (Hi/Lo Grades 4-6) Minerals (Hi/Lo Grades 5-6) Fossils (Hi/Lo Grades 5-6) Igneous Rocks (Hi/Lo Grades 6-7) Sedimentary Rocks (Hi/Lo Grades 6-7) Metamorphic Rocks (Hi/Lo Grades 6-7) Weathering - The Breakup of Rocks (Hi/Lo Grades 6-7) A Million Years in the Life of a Rock (Hi/Lo Grades 6-7) Plutons (Hi/Lo Grades 6-7) Bowen's Reaction Series (Hi/Lo Grades 6-8) Marking Time Geologically (Hi/Lo Grades 6-8) Other Ways of Determining Age (Hi/Lo Grades 6-8) Absolute-Age Dating (Hi/Lo Grades 6-8) Principles of Relative-Age Dating (Hi/Lo Grades 6-8) Fossils Tell A Story (Hi/Lo Grades 6-8) Iron (Very Quick Reader; Grades 2-5 Readability) Minerals (Very Quick Reader; Grades 3-5 Readability) Diamonds and Graphite (Very Quick Reader; Grades 3-5 Readability) Sand and Gravel (Very Quick Reader; Grades 3-5 Readability) Limestone (Very Quick Reader; Grades 3-5 Readability) Igneous Rock (Very Quick Reader; Grades 3-5 Readability) Oil and Natural Gas (Very Quick Reader; Grades 3-5 Readability) Mining Minerals (Very Quick Reader; Grades 3-5 Readability) Igneous Rocks (Very Quick Reader; Grades 4-5 Readability) Sedimentary Rocks (Very Quick Reader; Grades 4-5 Readability) Metamorphic Rocks (Very Quick Reader; Grades 4-5 Readability) Rocks Are Like Cookies (Very Quick Reader; Grades 5-6 Readability) How Do We Get Salt?

If the continents of the earth move and grow, why don't we notice that? One, we really don't see what whole continents look like in real time, and two, they move so slowly that people die before any noticeable changes can take place.To begin with, the current geologic theory was that the crust was all stationary, and continents were relatively unchanging - they didn't move around.Alfred Wegener knew that other people had made observations of the fit of the coastlines.(Short Reader; Grades 3-5 Readability) Where Does Salt Come From?(Short Reader; Grades 3-5 Readability) Stalactites and Stalagmites (Short Reader; Grades 3-6 Readability) Three Kinds of Rocks (Short Reader; Grades 5-6 Readability) Sedimentary Rocks, Rocks on Earth's Surface (Short Reader; Grades 5-6 Readability) Fossil Hunters (Grades 1-2) Caves and Caverns (Grades 3-5) Brendan Buckley's Universe and Everything in It (Grades 4-6) Paleo Bugs: Survival of the Creepiest (Grades 4-8) The Siege (Guardians of Ga'Hoole Book Four) (Grades 4-8) Learning About Rocks (Grades 2-3) Rating Rocks (Grades 3-5) Putting Rocks to Work (Grades 4-5) Igneous Rocks (Grades 4-5) Metamorphic Rocks -- Rocks that Change (Grades 5-6) Minerals - Building Blocks of Rocks (Grades 5-6) Identifying Minerals (Grades 5-6) Clastic Sedimentary Rocks (Grades 5-6) Non-Clastic Sedimentary Rocks (Grades 6-8) Rocks Rock!

Putting all this data together, Wegener concluded that the continents were at one time all together in a giant supercontinent and that somehow they broke apart and migrated to their present location. He called this theory continental drift and talked to many other scientists and geologists about it.
