Question

Describe why echo sounding is better method of mapping the ocean floor than lead weight on the line.

Answer 1

Because it is more accurate, faster, and cheaper than useing lead weights on a line.

Answer 2

Echo sounding is a better way of mapping ocean floors because this method can be used to measure larger depths of the ocean.

Step-by-step explanation:

• This method of mapping, the 'depth of the ocean' uses sound waves to send and receive signals from depths of ocean enabling accurate mapping.

• The lead weight on line method can also be used for mapping ocean floor but this method is better for up to 50 meters of depth.

• For greater depths, the lead weight method does not give exact results.
