Not quite vocab! : )

Pangea
ALL PLAY!
Not really a natural disaster question.. but it's ok : )
List as many reasons as you can to support the theory of continental drift!! We went over 4 in class... it should be based on these! Whichever groups get the most (or all) get the points!
*similar rocks were discovered on different continents
*overall movement of the tectonic plates
*matching shapes of continents (like puzzle pieces)
*similar fossils found on different continents
ALL PLAY!!!
**each group gets 1 minute to label the sheet Mrs. Curless passes out! Whichever groups get them all right, get the points!
Hope you got them right!
