Scientists know the depth of the ocean by using technology like the Deep Worker or the "Alvin". It takes them to the bottom of the ocean so they can study ocean life. Also ships use sonar (SOund NAvigation and Ranging) to see what the depth of the ocean is.
most of the beautiful coral reefs have disappeared
Iam not known
scientist use sound
4590 Meter.
Definitely each day scientist find more life down there. JASMYNELOVESFLOWERS
You use Sonar
A 30cm Ruler.
To find out the ocean`s depth
AN APPRATUS calld sonar is used to locate underwater objects and to find the depth of water.it sends out high freqncy sound viberations called ultasonic viberations,into the water.the time taken by the viberations to return is then used to calculatethe distance of the reflecting surface.
Metres.
Usually deals with hypersonic wavelengths, kinda like how bats see, and they see how long it takes to hear the signal back. Then they divide the time by 2, since the time given was the time down and back up, then they find out the speed of the hypersonic wavelength, and plug it in to the sound.
Bye internet
Sound energy is used by living things in order to hear stuff, and alsoto operate ultrasound equipment to see babies before they're born andsmash kidney stones, and also to operate SONAR to find enemy subsand fish and measure the depth of the ocean.
