Question

explain why snowshoes stop you from sinking into the snow

Answer 1

they increase the surface area of our feet and the pressure applied on snow reduces

Answer 2

$\huge\mathbb{\underline{Answer:-}}$

The area of snow shoes (which comes in contact with the snow) is much bigger than the area of sole of ordinary shoes worn by us in everyday life. So, the snow shoes exert less pressure (= force /area) on the soft snow and stop the wearer from sinking into it.
