How big is just one gigatonne of ice

So how big is just one gigatonne? This unit of mass is equivalent to one billion metric tons, 2.2 trillion pounds, or 10,000 fully-loaded U.S. aircraft carriers. Central Park is 4 kilometers long and 0.8 kilometers wide. A gigatonne of ice placed here would extend 341 meters (1,119 feet) high.

hope this helps...

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
