Presentation transcript:

What is it and what evidence supports it?

Look at the globe for today’s world… do you believe it could have been like this? Evidence 1 – Continents fit together like a puzzle

Why weren’t Wegener’s ideas accepted? They wanted more… EVIDENCE to explain. Wegener’s biggest problem was explaining how the continents could have moved! Alfred Wegener gets most credit for the idea that the continents have moved to their current locations…

?? ? ?? How can you map something so far away? You can’t just dive down there… Evidence 2

Using sound waves to find the distance to objects

How Far? Distance = Rate x Time It takes 2 hrs. at 52 mph… How about with you?

Evidence 2 – Finding of ridges or “seams” in the ocean floor

Evidence 3

Evidence 4

Evidence 5

Long before Volcano Locations

So that’s cool and all… but how could the continents have moved???
