the dropping off of weathered rock is deposition
By the water scraping along it so often that little bits come off.
When a rock gets weathered or eroded there are small pieces that come off and become sand. I suppose if the rock isn't strong a larger piece might break off and form a pebble or something small. Otherwise I don't really know what to tell you.
The term is deposition.

Deposition is the answer
They can be moved by the rain coming down and landing on the rock so the rock brakes and crumbles off.Also it can be caused by the wind blowing on the rock and bits can fall off the rocks.
because they are broken off into little bits and so get smaller and gradually worn down
It gets worn away by the sea because it is simply eroded which mean when water is moving fast the waves crash against the rock and bits fall off into the sea. when this happens the waves carry the pieces of rock away and they end up on a beach as sand or at the bottom of the ocean.
its called silt

Transportation is a term used for the movement of sediments via transporting agents such as water, wind, ice and even gravity. Transportation is evident in rivers and streams where you can find pebbles of rock some of which might be perfectly spherical and others not quite spherical but round. Such round shapes are the result of transportation which causes attrition of rocks by hitting other rocks or materials, for example, in rivers, breaking bits off to form round shapes as supposed to angular shapes which are predominant in rocks which are freshly eroded.
The two theories if hoodoo formation (aside from metaphysical reasons) are: * Water eroded and cracked the harder cap rock on the hoodoos to be. The water in the cracks froze and thawed cracking off chips which were washed away. When the rough shape of the hoodoo was formed the cap rock biscuit acted as an umbrella to protect the center of the hoodoo. The outer edges then rounded off with ongoing spalling of rock in cycles of wetting and freexzing. * Sand blown by the wind eroded the hoodoos from soft rock. This is discredited by the lack of a single eroded side to the hoodoos caused by prevailing winds
When the mountains got eroded, sediments broke off, and rolled down the mountain into the lowlands, that were oceans at the time, and the pressure from all the rocks fused them together, making it a sheet of sedimentary rock
As the continents broke apart and drifted, so bits would be eroded way, other bits would also break off and may be left behind. Natural erosion would also reshape the land, and some pieces could even have turned round.
