The border between the outer core and inner core is how many kilometers beneath the crust?
The border between the inner core and outer core is approximately 5115 kilometers below the crust.
CRUST MANTLE CORE The Earth's outermost surface is called the crust. The crust is typically about 25 miles thick beneath continents, and about 6.5 miles thick beneath oceans. The crust is relatively light and brittle. Most earthquakes occur within the crust. The crust in this image is much smaller in the real earth!
When two continents begin to drift toward one another, its because the tectonic plate which the ocean between them lies on is being subducted beneath another tectonic plate; basically the oceanic crust (land) beneath the ocean is being pulled down underneath another piece of crust. Once all the oceanic crust has been swallowed up, there is no more ocean left between the continents and so they 'meet'. The continents don't get pulled down beneath one…
