2. Ocean water depth (from the surface of the ocean down to the surface of the ocean floor) increases systematically when moving
away from mid-ocean ridges. What is a possible explanation for this? How does this help explain the observation that the tops of the seamounts along the Hawaiian-Emperor chain get deeper with increasing age?
The motivation behind why the profundity of sea which is estimated as the distinction between the sea surface to the sea floor increments as we move from the focal point of the mid ocean edge is that mid oceanic ridge is the spot from where the new the magma is rising to the top and is getting set (it's where two sea plates are getting separated and framing dissimilar plate limit.
This is from where the magma is coming up to the sea surface) and consequently the sea floor is at least depth at the focal point of the mid ocean ridge and in this way the distinction between the sea water surface and the sea base is least at the focal point of the mid ocean ridge.
It will rise as we move farther from the focal point of the ridge and this is the motivation behind why the ocean Mount beat along the Hawaiian Emperor chain gets further with expanding age on the grounds that the expanding age rocks are helter-skelter from the mid ocean ridge.
The reason why the depth of ocean which is measured as the difference between the ocean surface to the ocean floor increases as we move from the center of the mid oceanic ridge.
This happens because mid oceanic ridge is the place from where the new the magma is coming to the surface and is getting solidify (it's the place where two ocean plates are moving apart and forming divergent plate boundary from where the magma is coming up to the ocean surface) and hence the ocean floor is at minimum depth at the center of the mid oceanic ridge and therefore the difference between the ocean water surface and the ocean bottom is minimum at the center of the mid oceanic ridge and it will increase as we move away from the center of the ridge and this is the reason why the sea Mount tops along the Hawaiian Emperor chain gets deeper with increasing age because the increasing age rocks are off center from the mid oceanic ridge.
In the age of exploration.... Prince Henry showed the Portuguese how to navigate by studying the sun and stars until later on, he showed them the compass navigation as the only technology advance which made possible for them.
