2.Fossels - there is coal and plants in Antarctica
3.Geological features - the mountain ranges in Europe and north America are the same
4.climate change - you can find call in Antarctica



Seafloor Spreading-Explain it.

Identify 2 evidences that helped prove the sea floor was growing and explain each one.

1.magnetic reversal-magnetic field reversals definition. Changes in direction or orientation of the magnetic field of the Earth.  Great!

2.age of the rock - scientist have taken samples of the rock and some are a lot older than the other.  Good!

  6. I have a feeling that some people didn't read your post. You didn't say how the magnetic reversals were proof of seafloor spreading.
