a) The hiker’s weight is distributed over the area of the snow shoes, which reduces the pressure on the snow below and minimizes sinking
into the snow.

b) The snow shoes increase the normal force of the snow on the hiker.
c) The snow shoes increase the upward pressure of the snow on the hiker. d) The snow shoes compact the snow making it harder to sink into it.
e) The hiker’s weight is reduced by wearing large area snow shoes.
