When sediment settles, at the bottom of a lake for example, more sediment will fall later on and the cycle will continue, making the sediment that fell first the oldest. So, after all of that science stuff, we can say that the father down you go, the older it is.
At the greatest distance from a mid oceanic spreading centre.
Main locations of sedimentary rock is at the bottom of a water source such as an ocean.As rivers flow to the sea, they may carry mud, sand, pebbles, and boulders along the way. The river drops this material, called sediment, into the sea. As layers of sediment build up over a period of many years, the great pressure of all these layers changes the sediment into sedimentary rock. Therefor you might be able to find sedimentary rock at the bottom of the ocean or a lake or river.
Somewhere at the bottom of the Marianas Trench you would find the oldest rock of the oceanic crust. Somewhere else, however, there are older rocks on the ocean floor--those deposited by icebergs that have broken off of glaciers. Those erratic rocks could be much older than the oldest oceanic crust.
Where would you find the most invertebrates
It would be found in the lower layers, rather that younger fossils which are found in the upper layers. ♥
you would expect to find a sword or a dagger at a scabbard.

I would expect to find Koala bears and kangaroos.

At which national park would you expect to find "hoodoos"?
