abyssal plains
Conglomerate rock is most likely formed from pebble-sized sediment deposited in shallow water at an ocean shoreline. As the pebbles accumulate, they cement together to form the rock.
Landforms such as deltas, alluvial fans, and beaches are formed by deposition. In these cases, sediments are deposited by rivers, wind, or waves, resulting in the accumulation of material and the creation of new landforms.
No, the soil in a delta does not primarily come from volcanoes. Deltas are formed from the accumulation of sediment carried by rivers and deposited as they flow into a body of water, such as an ocean or lake. The soil in a delta is typically a mixture of silt, sand, and clay particles eroded from the land upstream.
Sandy beaches are formed by the accumulation of sand particles eroded from rocks and minerals on land. These particles are carried to the coast by rivers, wind, and ocean currents, where they are deposited and shaped by waves and tides to create the characteristic sandy shoreline.
Where a river which transmits a great deal of material arrives at the sea and there is little tidal range a delta will form. Example the Nile into the Mediterranean or the Mississippi into the Gulf of Mexico. The Amazon & the Congo, which flow into an Ocean, the Atlantic in these examples, do not form deltas because the ocean currents distribute the outflow of material into & along the ocean currents.
You could be thinking of a delta or abyssal plains.

The four bodies of water that major rivers empty to are the Pacific Ocean, Artic Ocean, Indian Ocean and Atlantic Ocean. Those or some big lakes.
The Zambesi Rivers flows into the Indian Ocean.

The Mediterranean doesn't "empty" into anything. Rivers flow INTO the Mediterranean, not out of it. It is a SEA, primarily fed by the Atlantic Ocean.

The Yenisey, Lena, and Indigirka rivers all empty into the Arctic Ocean. These rivers primarily flow through Siberia in Russia, draining into the northern seas, including the Kara Sea and the Laptev Sea, which are part of the Arctic Ocean.
