Age of Ocean Floor Pre-Test
1. Along the edges of the plates of North America, South America, Africa and Eurasia. I think this because of the Mid Atlantic Ridge. When molten lava comes up, it forms a new layer, and making it bigger and pushing the older rocks to the side. It is in between all of the continents that I stated above, so the rocks that are being moved would be pushed to the edges of these plates. Since the Mid Atlantic ridge is new in the middle, the rocks get older as you get further away from it on either side. So, the oldest parts must be on the edges of the continents I stated.
2. No, I don't think so. I say this because one of the oceans (likely the Atlantic) was created through seafloor spreading, which means that it must be newer than other oceans.I know that some oceans had formed a very long time ago. The Pacific ocean is very large compared to other oceans, which I why I think that it slowly got bigger and bigger overtime, but since it is so big, it must have been around much longer that smaller oceans like the Atlantic or Indian.
3. Well that depends, because some continents were created after others, while some have been around for a very long time. some rocks on the land have been found to be around two billion years old, while others are quite modern. The ocean floor, however, has also been around a long time, with very old areas in some parts, but things like the Mid Atlantic ridge or molten lava coming up and creating a new crust makes some areas more modern. In all, they both have ancient areas and they both have more modern areas.
