why is sonar a more accurate way of mapping the ocean floor than weighted lines? explain! (atlease 3 sentences pleaz)
Multibeam sonar measures the depth of the sea floor, technically it measures the length of time it takes for the sound waves to travel from the boat to the seafloor and back as an echo. This measurement is used to figure out how deep the water is. This is much more accurate than sounding which is the process of using a rope that has weight attached to it. This method of seafloor mapping was very time consuming, especially when charting deep water. Unlike the newer method of using sonar.
a joined transmitter and beneficiary called a transducer sends a sound heartbeat straight down into the water and the beat travels through the water and bouces off the sea base with the goal that the transducer can pickup the reflected sound
unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
why is so...
