a Flood
There are two types of crust, oceanic and continental. Oceanic crust is covered by most of the oceans, but water from the oceans flows over parts of the continental crust and we call them seas. The water covering the crust is relatively thin so that it is usually not counted when discussing the crust.
A low, broad, dome-shaped volcano built up of overlapping built up of basaltic lava flows and often covering a very large area.

A confluence
A river usually flows eventually into the sea.
A river is a large stream of water that flows across the land and empties into a larger body of water. A river usually empties into a sea or ocean.
The Columbia Plateau was formed by extensive lava flows from volcanic eruptions millions of years ago. These lava flows covered a large area of land in the Pacific Northwest, creating a distinctive geological region known as the Columbia Plateau.
The Amazon is a large river in Brazil that flows into the Atlantic ocean.
Usually the sea.

The maria of the moon are covered with basalt, a dark volcanic rock generated from ancient volcanic eruptions. This basaltic material formed vast plains on the moon's surface after lava flows filled large impact basins billions of years ago.
Electrical wires have plastic covering as when electric current flows through the copper wires and mistake we hold it so we may get an electric shock.
