Why does snow melt in our hands?

Snow is frozen water, which is at a temperature of $0 ^\circ C$ and below. Our hands are at body temperature, which is close to $37 ^ \circ C$ . Hence, our hands are much warmer than the ground, and so there will be more heat transfer to the snow, which causes it to melt more.

The ice starts to melt when our hand and the snow reaches thermal equilibirium.Hot body transfers heat to a cold body. :)

pretty simple ! because in winters ground's temp fall with the atmosphere temp but our body temp is still 37*c so it is much warmer than temp of ground so snow melts faster in our hands

Ground cold, hands hot. Heat makes snow and ice melt faster.

I like the 4th answer very much.. fear of its safety...
