What i think is, as there is less friction on a muddy road it is difficult to walk on it.
Water has less friction, that is why usually we see cautions warning us not to walk on wet floor as we'll slip and fall, so when soil is in contact with water it reduces the friction of soil.
It is difficult because if snow is soft our feet sink and when the snow is frozen we may slip.
Snow is soft when it first falls on the ground. People's feet sink in the snow. Frozen snow that has been on the ground becomes hard and slick making traction difficult.
It is because the reaction given by the road to the foot to move forward in least .That is why it is very difficult to work on a muddy
It is difficult to walk on an icy road, because your feet keep slipping on the ice.
kkkk
it is because smooth surfaces have less friction so when friction is less it is hard to walk
there had a possibility to slide
Friction is needed for stability in movement.
A walk. In the snow.
Always walk on yellow snow.
Snow is slippery.
they go to the Warehouse and buy snow shoes.
they have legs...
Blizzard conditions would make photographing snow crystals difficult.
Not exactly, but sometimes it can become grayer.
You can always walk a penguin up a snow covered hill.
snow is hó [hoː] not so difficult to pronounce it :)

Snow shoes, skis, or if daytime thaw has created a strong crust on the snow.
it was climate control. snow made growing food difficult.
