aerodynamic, or hydrodynamic.
there fins push thorugh the water
Water beetles move through the water by thrusting their legs back and forth. This allows them to quickly move and catch prey.
Penguins can move quickly in the water, using their flipper-like wings to "fly" through the water at speeds up to 15-25 miles per hour. On land, however, penguins waddle at a slower pace due to their anatomical structure, which is not designed for speed on land.
There tail.
Yes, the temperature of water can affect how quickly food coloring spreads through it. Warmer water molecules move faster, allowing the food coloring to mix more quickly compared to colder water where the molecules move slower.
A non living "thing" cannot move without a living thing or a force moving it.
One thing to be sure of, is that you don't get STINGRAYS and MANTARAYS confused. Mantarays sip..stingaz don't
When you dive, you move quickly through water due to a combination of gravity pulling you down and your streamlined body position reducing drag. Additionally, the propulsion from your kicks and arm movements also help you move efficiently through the water.
Depth strider is an enchantment applied to boots which allows you to move more quickly in water. At its highest level, you move as fast in water as you do on land.
Fast-moving water, such as in rivers and streams, can move sediment quickly due to the force of the flowing water. Wind can also move sediment quickly, particularly in arid environments where there is limited vegetation to anchor the soil in place.
air and water
if aliquid is evaporating the particles are far apart and move very quickly randomly ! :D
