Question

1. why
is the difference in hearing up
of land and water?​

Answer 1

Answer:

Solar heating of the Earth's surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces. ... This differential heating is passed on to the air above by conduction which causes air expansion and changes in pressure.

Answer 2

Answer:

the difference is that in air the sound have more travel speed but in water our ears are in the water and the speed of sound is less in water so we are not able to hear properly in water
