There are 3 main ways for them to be formed. Sedimentary rocks are formed from dirt and sand, and can be found in rivers. Igneous rocks are made from molten magma or lava. Metamorphic rocks are made from already existing rocks, and are changed by pressure or temperature.
They fragment and become jagged, they become rounded by means of water erosion, which is why rounded rocks are found by rivers, creeks, etc.
Sedimentary rocks are typically found in layers along the sides of rivers and at the mouth of rivers. One very famous place where sedimentary rocks are most prevalent, more than metamorphic and igneous rocks the two other types of rocks, the Grand Canyon in Arizona. These rocks are associated with the vivid red rock layers seen throughout the canyon and took millions of years to form.
Most of the metallic sulphides are insoluble in water so such compounds can not move with rivers to the sea so their maximum ratio is in rocks form.
From rocks in rivers and lakes and when the rocks break up over time the sediments inside the rocks go into the rivers and lakes and overtime into the water supply.
