Why is sonar a more accurate way of mapping the ocean floor than weighted lines?

Answer 1

sonar (coupled with computer enhancement) can actually give a picture
of the ocean floor

weighted lines give a collection of data points, so bottom contours and other features are not necessarily revealed
... the lines are also subject to currents, creating possible errors

Answer 2

Thx very much.😊

Answer 3

A sonar is more accurate when it comes to the way of mapping the ocean floor than weighted lines because, a sonar has a ‘ping’ that travels through the water and bounces off the sea base, which then succeeds once the transducer picks up the reflected sound of the ‘ping’. Weighted lines are less accurate because they give data points, so bottom contour and different features needed aren’t given which can give possible errors.
