Continental deposits of gravel and sand typically form through processes such as erosion, transportation, and sedimentation. These materials are often carried by rivers and streams from higher elevations, where they are eroded from rocks and soil. As the water flow slows, the heavier particles, like gravel and sand, settle out and accumulate in low-lying areas, riverbeds, or deltas. Over time, these deposits can become significant geological features, shaped by further weathering and sedimentary processes.

You run the sand and gravel over different size screens depending on how many sizes you wish to sort the gravel into. In most large gravel pits, a deposit is sucked up with a pump (with water) through metal pipe up to a steel tower.Using gravity the sand,small pea gravel and larger gravels are separated. In most gravel pits the water turns green over time because of the Iron in the deposits.
Sand and gravel are dug out of open quarries on the surface.

I attached a picture with the answers on it
A continental deposit of gravel and sand is typically created by the erosion and transportation of rock fragments by rivers, glaciers, or wind to a new location. These deposits can accumulate over time, forming layers of sediment that eventually solidify into sedimentary rocks like sandstone or conglomerate. They are important sources of building materials and may also contain valuable minerals or fossils.

Sand and gravel can be separated by sifting them through a mesh, that will allow the sand to fall through, but will hold back the gravel.
