Pools in streams typically form in areas where water flow slows down, often due to changes in channel geometry, such as bends, or the presence of obstacles like rocks or fallen trees. These features create localized areas where sediment can accumulate, allowing for deeper sections to develop. Additionally, pools can form downstream of riffles, where the water's velocity decreases as it transitions from the fast-moving flow over the riffle to the slower-moving water in the pool. Overall, the interaction between water flow and the streambed topography is key to pool formation.
They drink from small pools of water or streams.
On the floor! E.g. in hollows where dripping water can accumulate. Often in streams as in surface streams. Or as "gour pools" (aka in USA, I think, "rimstone pools") - formed by calcite deposits forming natural weirs in the trickle of water flowing through them. These can be very beautiful.
They get moisture from their food - also they will (if necessary) seek out pools, streams etc to drink from.
Sure. There are natural pools and streams created by the water that made the cave in the first place.
Raccoons get their water from streams, rivers, lakes, puddles, pet bowls, ponds, and swimming pools.
Streams can slowly join together to form rivers.
Varicose veins form when blood pools in the veins.

Most wild animals get water by simply drinking it from pools and streams. A few get it as moisture from plants they eat.

When two streams come together, it is called a confluence. At a confluence, the two streams merge to form a single stream.
