Plate movement

1. Rodinia and Pangaea were similar because the continents were close together. They were different because with Pangaea the continents fit together like a puzzle.


2. Between 080 and 150

3. If the continents looked like Pangaea today, I think that there would be more people traveling or living in different countries. There would be less countries because some would probably come together as one since they are so close together.

4. I would start my civilization in Africa because it is big and has a lot of land.

Earth's layers

1. The deepest mine in the world is 3.6 kilometers deep.

2. In order to reach the mantle I would have to dig 30 km.

3. If Iwere able to reach the mantle it would be very hot. The rocks would be liquid and in the upper part of the mantle, I would see rocks moving more smoothly than it would at the bottom. As I went towards the outer core it would be even hotter. It would be liquid with different types of metals in it. The inner core would be the hottest of all the layers. Unlike the outer core it would be solid with mainly iron inside. As I made it up to the crust I would see a thin layer of rocks.

1st quarter blogs

I think I deserve a 100 because I did all of my blog posts and I did them correctly. My first blog was the best because I really like the picture I put up there and put a lot of thought into it
