Zone 3 is a tropical zone, while zones 2 and 4 are temperate.
Since Zone 3 is around the equator and between the two tropics, it is a tropical zone.
Zone 2 and 4 are temperate since they are farther away from the equator, but not too close to the North and South poles.
I hope this helped! :-)
Answer:
Sound is a type of energy made by vibrations. When any object vibrates, it causes movement in the air particles. These particles bump into the particles close to them, which makes them vibrate too, causing them to bump into more air particles. This movement, called sound waves, keeps going until they run out of energy.

At the interface of two fluids, there is a difference in pressure. This leads to the existence of a surface force, the surface tension, that shapes the fluid.
The surface tension of water is roughly 72 dynes/cm,
However, that is highly dependant on the characteristics of the considered material (physical and chemical), and thus all fluids (and thus liquids) do not have the same surface tension.
