A. Ice would not melt.

B. Lakes would freeze from the bottom up.

C. Icebergs would float higher in the water

D. Freezing water would cause more cracking in rocks than it does now.

Answer 1

.obvi b>

this is the main reason y acquatic animals can live in a place whose temp is below freezing pt

due to anomalous behavior of water below 4 degree celcius instead of becomin heavy

due to increasin density it becomes lighter so even though the top is 0 degree bottom part is 4 degree.

bingo!!

Answer 2

none are true.....i think

Answer 3

B. Lakes would freeze from the bottom up.

The reason all of the other things happens is because water is the most dense at 4 degrees C not at 0. This is because water wants to make a crystalline structure when it freezes giving it greater volume.
