Evidence of Continental Drift Scaffold

Alfred Wegener supported his theory of continental drift with several pieces of evidence.

Evidence in the Fossil Record:

  1. In the _______________ record of several continents, groups of plants and animals showed a _________________ , orderly _________________ .
    1. At some point in time their _________________ paths _________________ .
    2. Explain what happened.  






  2. Paleontologists found _________________ of some plants and animals that seemed to have an odd pattern of _________________ .
    1. Species of ancient _________________ plants and animals were found to span _________________ day oceans.
    2. _________________ species were found on _________________ sides of oceans.
    3. Explain what happened.  






Rock Strata Evidence:

  1. Wegener observed that rocks in Eastern _________________ matched those of northeastern _________________ .
    1. The _________________ of rocks, the _________________ of the rocks and the patterns (or layering) of types of rocks matched. Matching the rock involves examining the:
      1. _________________ _________________ (sandstones, shale)
      2. _________________ _________________
      3. ____________________________________
      4. Bonus: a particular rock may have distinctive characteristics such as mineral or _________________ _________________ ( _________________ ) or _________________ characteristics ( _________________ ).
  2. Mountainous ranges of similar _________________ and _________________ exist in _________________ North America, _________________ and _________________ .
  3. Explain what happened.  






Evidence from Paleoclimates:

  1. The continents of the _________________ hemisphere show _________________ of glaciation.
    1. The tell-tale _________________ that glaciers leave as they _________________ across bedrock were _________________.
    2. It appeared as if there were glaciers at the _________________ and glaciers coming from the _________________ onto the _________________!
  2. Corals are small _________________ that build up their homes from calcium carbonate (CaCO3) found in _________________ _________________.
    1. Large _________________ of corals create vast _________________.
    2. Coral will live only in _________________ water, but _________________ coral reefs are found in _________________ and _________________ _________________.
  3. Coal is the remains of _________________ _________________ accumulating over eons, being _________________ and then _________________ by overlaying rock.
    1. Vast coal fields exist in _________________ areas such as _________________ America, _________________, and _________________!
  4. Explain what happened.
