The Earth

Dinosaur bones have helped us see in to the past and tell us what the earth looked like 10000 years ago. We know that the earth’s continents were connected together as shown in the picture below. We know that they were connected because there are some dinosaur bones found in southern America and some found in Africa. Now I don’t think they swam.

Before

After

As you can see the two pictures look very different. That is because the continents are slowly drifting away from each other due to seismic activity. We new that the earth looked like that because we have dug for them. This is why digging things up doesn’t just tell us what was in that area it is telling us what that area looked like back then. You can also see that all the continents connect together like a sort of jigsaw puzzle. How South America fits into Africa or how North America and Canada fit into Asia. This is all because they were suppost to be there not all separate.
