The discovery of the Mid-Atlantic Ridge was confirmed through the use of sonar technology in the mid-20th century. This technology allowed researchers to create maps of the ocean floor and revealed the presence of the underwater mountain range running along the Atlantic Ocean.
The instrument used to measure the depth of the sea is called a bathymeter or echo sounder. It sends sound waves to the ocean floor and measures the time it takes for the sound waves to bounce back, allowing for the calculation of water depth.
Gneiss is more likely to form at great depths where mountains are being pushed up. This is because gneiss forms through the process of high-grade metamorphism, which requires high pressures and temperatures found at greater depths in the Earth's crust. As mountains are pushed up, rocks are brought to these depths and subjected to the conditions needed for gneiss formation.
The place where the ocean floor suddenly plunges downward is called a submarine trench. These deep underwater valleys form at tectonic plate boundaries where one plate is being pushed beneath another in a process known as subduction. Submarine trenches can reach depths of over 10 kilometers and are some of the deepest parts of the ocean.
Hurricanes typically form over warm ocean waters near the equator. The majority of hurricanes originate in the Atlantic Ocean, particularly in the Caribbean Sea and the Gulf of Mexico. They can also form in the Pacific Ocean, primarily in the region near Southeast Asia and the western coast of North and South America.

The full form of SONAR is "Sound Navigation and Ranging". It is a technique that uses sound waves to detect and locate objects underwater.
Yes, dolphins have eyes. Their eyes are located on the sides of their heads and are adapted for underwater vision. Dolphins rely on their eyesight, along with echolocation, to navigate and hunt in the ocean.
The answer is ASDIC
SONAR - sends out a pulse of sound... The resulting reflected sound is analysed to form a 'picture' of what's around the vessel.
Hydrographic surveyors (as people who map the ocean floor are called) typically utilize sonar systems to measure water depths. The simplest form is a single beam echosounder mounted on the underside of a boat floating on the surface. Like a flashlight that illuminates a small area in the direction it is pointed, a single beam sonar is pointed down and ensonifies a small area on the seafloor beneath it. The echosounder emits a pulse of acoustic energy into the water. This energy will travel down through the water; when it hits the seafloor (or anything else in the water column) some of the energy will be reflected back towards the echosounder. The speed of sound in water varies based on temperature, salinity and pressure, but is usually in the neighborhood of 1500 meters per second. By measuring the amount of time it takes for the acoustic energy to make its round-trip journey, and multiplying it by the speed of sound in water, we are able to calculate the depth.
Killer whales use sonar which is a form of echolocation.
Sonar was gradually developed and improved over many years, but the first operational form of sonar as we now know it goes back to about 1918.

Sonar for one thing
No , because it has to be deep inside the earth so it ca be pushed up.
