What 2 continents have the best fit?
For the best fit, which continent forms the 'core' of Pangaea?
Which continent is now part of Eurasia but acording to theory was once a separate continent that moved northward to its current position?
Why isn't the fit perfect if the continents were once all part of Pangaea? Suggest at least 2 reasons.
If the continents were drawn on a Mercator map, would your chances of finding a fit have been improved? Explain.
Scientists theorize that the continents are still drifting apart. What will be the eventual position of North America with respect to Eurasia?
Theorize on how the Atlantic Ocean formed.

OK - one more day to work on your Word Tiles!
Word Tile HINTS: In eukaryotes, cell division is complex and occurs in two main stages.
The first stage, division of the cell nucleus, is called mitosis.
The second stage, division of the cytoplasm, is called cytokinesis.
In prophase, chromosomes become visible. In metaphasae, chromosomes line up at the middle of the cell.
In anaphase, spindle fibers help chromosomes move apart.
In telophase, chromosomes move far apart towards centrioles.
During cytokinesis, cytoplasm pinches off to form two new daughter cells.
