Answer 1

$\huge\underline\red{ANSWER}$

☞The density of the water is highest at 4°C.

☞So the at winter the water having temperature 4°C goes to the bottom of the tank and the water having less temperature will be at the surface.

☞Hence the freezing starts at the surface.

☞Also since the ice is lighter than water ice also stays at the surface.
