How is an echo sounder used to determine the bathymetry of the ocean floor?

They send down a sound wave (whose velocity they know) and measure how much time it takes for it to return.
Velocity=Distance/time
Distance=Velocity*time
They divide the distance by 2 (since the sonar wave has to return as well.)
They make thousands of these measurements to make a map of the ocean floor based on these distances.

What do scientist call the charting of the ocean floor?
Bathymetry
What is bathymetry?
The measurement of ocean depths and the charting of the shape or topography of the ocean floor. Bathos= Depth metry= Measurement
How do satellites determine the terrain of the ocean floor?
Satellites use radar altimeters that are specially made tomeasurethe height of the ocean surface. The satellitesmeasurethe height of the ocean surface with an accuracy of 3cm realitve to the center of the earth.
How did scientists determine how the ocean floor is?
Radiometric Dating.. APEX!
How do scientists use sound out to figure out the depth of the ocean?
They use an Echo Sounder. Many pulses of sound per second are sent to the ocean floor & the time it takes to rebound is measured and therefore the depth is calculated.
