Solifluction is when the top layer of soil moves slowly down a slope because of melting snow or ice.
Solifluction is a natural process that happens in cold places. It can be a problem for building things.
Examples:
Solifluction happens when the snow melts and the ground moves.
The road was damaged by solifluction.
Solifluction can make it hard to build things on hills.
The solifluction made the road all bumpy.
In the cold, solifluction can make the ground move like a river.
The solifluction is slow, but it never stops.
