The depth of the continental shelf varies. It is generally limited to shallow water, shallower then 490ft. Vertical relief is minimal at less then 20m. The slope of the shelf is also quite low, 0.5degrees

Oceanic crust is roughly 4 miles in average depth. Continental crust is on average 25-30 miles in depth.
The approximate average is 19. The actual average is 19 and 1/3
The average price of a 5th wheel continental kit is $1070. This an estimate of the average based on stores that are currently selling a 5th wheel continental kit.
you couldwrite something like: the whole class had an approximate average of 77%
The average continental rock is less dense than the average oceanic rock. This is why when an oceanic and continental plate collide, the continental plate does not get subducted. There are varyations within the continental plates however, with some rocks being muck more dense and some being much less dense than the average.

Other than an estimate for Antarctica (average 2 km of ice cap), there are no reliable estimates of average continental elevation. However, Asia, North America, and Africa have large areas of relatively high elevation as compared to Europe and Australia.
