V-shaped valleys by fast flowing rivers, and U-shaped valleys by glacier movement.
Fast moving rivers int he ocean are called currents. Currents are caused by the Earth's rotation. An ocean current is continuous.
Fast flowing rivers are more erosive and are light on the deposition of sediments. Slow flowing rivers allow for the deposition of sediment which create the meanders.
Mercury has the thinnest atmosphere so the fast winds from blown up stars go to the thin atmosphere, it will be easier to get in and change the atmosphere
fast-flowing liquid lava
The measurement of how fast the current is flowing is the Ampere.
If caught in a fast flowing river current you should swim parallel to the current and you should always go feet first so you know where you are going and your head does not crack open if you bump into anything
A fast flowing stream is called a rapid. Rapids are where the water flows downhill very fast and over underwater obstacles.

Well it is called rapids but I call it a waterfall
a rip current
The South Equatorial Current is a broad, westward flowing current flowing between approximately Venezuela and the south of Brazil. It is divided into three branches, each with different velocities - the range is 11.3 cm s-1 to 16.4 cm s-1.
A fast flowing river is faster
Jet streams

The jet stream is a fast flowing, river of air found in the atmosphere at around 12 km above the surface of the Earth just under the tropopause.
