A wave.
Measuring a wave from crest to trough in the verticaldirection will give the amplitude of the wave. It's called the peak to peak value (as it is is a measure of the distance from the positive peak to the negative peak -- the crest and trough). Measuring the wave in the horizontal direction from a crest to a trough will result in half a wavelength.Picture a water wave frozen on the surface of a pond. The distance (verticaly) from the bottom of a trough to the top of a crest is the amplitude of that wave. A measure of the distance (horizontally) from the bottom of a trough to the top of a crest is half the wavelength of the wave. (Note that athe use of "bottom of a trough" and "top of a crest" might seem redundant or even nonsensical, but is applied here in the hopes of clarity.)
From maximum (crest) to minimum (troth) in height.
A crest of the sea is the highest point of a wave. It is where the wave is breaking and the water is lifted up and pushed forwards by the wind.

[Improve]The loggerhead sea turtle slowly moves by their fins. When they move, they slowly press their fins against the water. This makes a power source which causes them to move along. Please save the loggerhead sea turtles from extinction!
The four ways the sea moves material are through currents (flow of water), waves (energy transfer through water surface), tides (rise and fall of sea levels), and sediment transport (movement of particles along the seabed).
The Central Trough is the deepest point in the Red Sea with a depth of 2,211 metres (7,254 feet or 1.37 miles). It runs straight down the centre of the Red Sea hence the 'Central Trough'.
A wave is disturbance or oscillation, that travels through matter (eg mechanical waves) or space (eg electromagnetic waves) accompanied by a transfer of energy. A wave can be transverse or longitudinal, depending on the direction of its oscillation.A single definition for the term WAVE is not straightforward. However waves haveA direction,A velocity,An amplitude,A wavelength.A waveformWaves are best described mathematically. ----------------------------------------------------------------------------------------------------------Parts of a Wave Transverse Wave For a transverse wave, there are five main parts that make up the wave. They are: the equilibrium or rest position, the crest, the trough, the amplitude, and the wavelength. The equilibrium or rest position is the imaginary line that represents where the string (for example) would assume if there was no wave traveling through it. The crest is the point on the wave that has the greatest positive displacement from the equilibrium or rest position. The trough is the point on the wave that has the greatest negative displacement from the equilibrium or rest position. The amplitude of a wave is the distance from the crest, or trough to the rest position. It is the maximum amount of displacement that the wave has. The wavelength of a wave is the length of one complete wave cycle. This means, the length from crest to crest or tough to trough, from the rest position over a crest and trough and back to the rest position, or any two other point that are one complete wave cycle. Longitudinal Wave For a longitudinal wave, there are three main parts that make up a wave. They are: the compression, the rarefaction, and the wavelength. Since the particles of a longitudinal wave are vibrating and moving in line with the wave, there are areas where the coils (of a slinky, for example) are closer together. These areas are called compression's. The areas where the coils are spaced out more are called rarefaction's. The wavelength for a longitudinal wave is very similar to that of a transverse wave. It is still the length of one complete wave cycle, but instead of it being from crest to crest, it is from compression to compression, or rarefaction to rarefaction, or any two other points that are at the same point on the wave cycle.
He had to do some navigation to travel trough the sea.
The Seine river is running trough Paris and it meets the sea at Le Havre
Stockholm is located along the Baltic Sea.
20-28 degrees Celsius trough the summer.
