At this point they are none of the above. They are sediment. If lithified they will form sedimentary rock.
Pebbles could be igneous, metamorphic, or sedimentary rocks.
A sedimentary rock called "breccia". The sharp angular pebbles making up the breccia could be igneous, sedimentary, or metamorphic. Breccias generally form close to the point of origin of the clast rock, having less time to round those sharp angular edges.
No. If it has rounded pebbles, it's probably called conglomerate, a sedimentary rock containing rounded rock fragments from 3/4" to 6' in diameter that may have a sandy matrix. Sandstone is made up of much smaller grains.
There are three main kinds of rocks that are named after the different ways that they form. The kind of rock that forms when molten rock cools is called igneous rock. Basalt and obsidian are some types of igneous rock. The other two kinds of rocks are called metamorphic and sedimentary rocks. Metamorphic rock forms beneath the earth's surface as a result of intense heat and pressure changes. Sedimentary rock forms from particles of material, literally called sediment, consisting of pebbles, shells, sand, and other fragments. The sediment hardens into rock over a period of time as the layers accumulate.
No, in order to be a metamorphic rock, it has to be a rock that undergoes extreme heat and pressure. What you're describing is the formation of a sedimentary rock called a limestone.
Pebbles could be igneous, metamorphic, or sedimentary rocks.
Many rapids, loads of all sizes from pebbles to boulders. igneous and metamorphic igneous and sedimentary rocks, sedimentary mud stones.
No. It's too late.Unless it gets eroded itself and eventually forms layers of sediment which may then get turned into rock.

Conglomerate is a sedimentary rock made up of rounded pebbles cemented together.

Rocks can be formed by particles of pebbles, sand or shells creating sedimentary rocks. When molten rock cools and hardens it will form igneous rocks. When there is pressure and intense heat on rocks, they form metamorphic rocks.
It's a metamorphic rock since it was formed from intense heat or pressure. Also because it was mined and sedimentary rocks have little pebbles. Lastly because igneous rocks can't be mined unless they were already on Earth's surface.

Conglomerate; a clastic sedimentary rock composed of rounded pebbles and sand cemented together.
