They send a I believe micro wave or radar wave down to the bottom and it bounces back and they measure the time of how long it takes to get back to the receiver and do a few calculations from the time they got and they have the depth. (usually the machines do the calculations for you. and it only take like .5 seconds to calculate everything if its like 100 feet or less.)
What else can I help you with?
Why are divers limited to depth when at sea?
because of the sea floor
What are two challenges of mapping the sea floor?
The depth and the vastness of the oceans.
What is the depth of the sea cucumber?
its ranges from about 183 meters down to the floor its ranges from about 183 meters down to the floor
What is the depth range of a sea cucumber?
its ranges from about 183 meters down to the floor its ranges from about 183 meters down to the floor
What is the reason for not drilling more of your own oil in the gulf of Mexico?
Depth of the sea floor. For example at 30,000+ feet of depth, it becomes increasingly difficult to drill for oil on the open sea.
Vine and Matthews determined that new ocean floor was being produced at ocean ridges by examing?
the magnetic pattern on the sea floor
How the depth of the sea determined by sound waves?
The depth of the sea can be determined by measuring the time taken for sound waves to travel from a source to the seafloor and back to a receiver. By knowing the speed of sound in water, scientists can calculate the distance to the seafloor based on the time taken for the sound waves to return. This method is known as echo sounding or sonar.
What part of ocean creates the sea floor?
acually its the moon, since it causes the tides to pound against the water making depth
Can a human live in the depth sea?
no human can live in the depth sea
How does the density of sea change with depth?
the density of sea increases with depth
What will exert more pressure the river water are the same amount of sea water?
The pressure exerted by a fluid is determined by its depth and density. While river water and sea water may be present in the same volume, sea water is denser due to its salt content. Therefore, at the same depth, sea water will exert more pressure than river water.
Process in which new sea floor forms as older sea floor is pulled apart?
sea-floor spreading
