What is older the continents or the ocean floor?
On average, continents are older than ocean basins. Due to the action of plate tectonics, ocean crust is being formed and destroyed continuously. The oldest oceanic crust is about 200 million years old, whereas continents, which are less dense than oceanic crust and tend not to be subducted into the mantle, can be more than 3,000 million years old in places.
Does the earths crust extend deeper below the continents or below the ocean basins?
Earths crust extend deeper below the continents than below the oceans basins (or at least this is what I think).
Why do continents float high relative to the ocean basin?
The continents are thicker and less dense than the materials that make up the ocean basins.
Why are andesitic and granitic rocks confined to the continents and ocean margins but absent from deep ocean basins?
The igneous rock underlying the deep ocean basins is basaltic, as its source material comes from the asthenosphere. Andesitic igneous rock is formed at colliding plate margins, where subducting oceanic crust is partially melted and undergoes differentiation as it rises through the continental crust. Granitic rock is less dense than oceanic crust and composes the continents.
Why the ocean older than land?
The ocean is older than land because it formed the land.
Which ocean has an area greater than that of all the continents combined?
Pacific Ocean
Which ocean has a greater area than all the continents combined?
Pacific Ocean
How do the ages of the rocks making up continents and those making up the ocean bottom differ?
Continental crust is normally much older than oceanic crust.
Which ocean is larger than all of continents of the world combined?
The Pacific Ocean is larger than all of the world's continents combined. The ocean covers an area of 63.8 million square miles, while the continents only cover 57.4 million square miles.
Which ocean is larger than all the continents combined?
