Continental drift/Seafloor Spreading.
Continental drift-Explain it.
Continental Drift is how the continents drifted to their current spot. Pangea was what they called the continents before they were split apart.
Identify 4 evidences the helped prove the continents where moving and explain each one.
1. Glacial Striations- glacial striations are where the glaciers slide across the rocks and made a mark
2. Mountain Ranges- there are minerals that have the same age and type of rock in one part of the world then there are the same type and age in a different part of the world
3. Puzzle- part of central american and part of Africa could fit together like a puzzle piece
4. Fossils- the messasaures was found in Europe and there was another messasaures found in central america
well done!
Seafloor Spreading-Explain it.
Seafloor spreading is magma that is forced upward and flows from the cracks and then becomes solid and turns in to the seafloor.
Identify 2 evidences that helped prove the sea floor was growing and explain each one.
1. Age- close to the cracks where the lava comes up the seafloor is younger and farther from the crack where the lava comes out the age of the seafloor is older
I liked how you explained continental drift.
ReplyDeleteI think it is really good. I liked that instead of pangea you used the word puzzle. It was very descriptive.
