Tonight I was stumbling through some sites and came across the UBasics and found their solution to the answer "What happens if i dig straight down?"
I first did the obvious thing of finding out that from my house I would end up in the sea south-west of Australia. Great.
Figure Left: Yellow slashes show Chain trend. Green slash, lower frame, Valley trend.
Then, I quickly started just swinging the map around to find where Land and Land would meet. I soon discovered that the hot spot responsible for building the Hawaiian Island chain is located approximately opposite of the Great Rift Valley of Africa. The trends of the Chain and Valley are very nearly similar.
My SlingShot Thought is: Are these features related to internal processes within the earth cores? Some type of...equation balance? force balance? What role does mantle convection come into play? Why have I never noticed this before?
If anyone has thoughts to add or documents for me to understand this potential connection better, please comment.
