Any factor which alters the density of the sea water causes a variation in the velocity of sound in seawater. Basically, changes in temperature and salinity will result in changes in density. This can cause large changes in velocity.

For example, seawater in the carribean with a temperature of 20C and a salinity of 37ppt might result in a velocity of, say, 1530m/s, whereas seawater in the North Sea with a temperature of 3C and a salinity of, say, 31ppt, would result in a velocity of, say, 1480m/s.

What is the speed of electricity or lightning compared to the speed of sound and light?

The speed of lightning is somewhere between that of light and sound which is why most scientists would agree that the speed of light and the speed of sound make a good comparison to that of lightning and electricity.


Is Transonic speed faster than Mach 1?

By definition, Mach 1 is the speed of sound. Most of the time it is used to refer to the speed of sound in air, but it can be used to refer to the speed of sound in any fluid. Mach numbers are multiples of this speed, so Mach 0.5 is half the speed of sound while Mach 2.5 is two and half times the speed of sound. The term "transonic" refers to a condition where the speed crosses over the speed of sound - so it refers to a range of velocities of airflow exist surrounding and flowing past an air vehicle or an airfoil that are concurrently below, at, and above the speed of sound in the range of Mach 0.8 to 1.2. In this respect - at least some of the velocities must be below the speed of sound, some at the speed of sound and some faster. The correct term for speeds that are exclusively faster than Mach 1 is supersonic.

What is the most important factor affecting seawater density?

The most important factor affecting seawater density is its temperature. As temperature increases, seawater density decreases, causing it to expand and rise. Conversely, as temperature decreases, seawater density increases, causing it to contract and sink.

Why can most land vertebrates not drink seawater?

Most land vertebrates cannot drink seawater because their bodies are not adapted to process the high levels of salt found in seawater. Drinking seawater can lead to dehydration and damage to their internal organs.

What can affect the speed at which sound travels?

The most relevant answer to this question is medium, the most prime factor affecting the rate of sound travel is the medium which carries the sound waves, sound is fastest in solids and slowest in viscous fluids.
