Layers of particles of which of the following states of matter can slip and slide over one another easily?

Layers of particles of liquid can slip and slide over one another easily.
The particles in a liquid are also attracted to each other, but not as strongly as in a solid. The particles are close together, moving constantly, and can slide past one another. Particles in a liquid will flow or glide over one another but remain at the bottom of the container. The attractive forces between particles are strong enough to hold a specific volume but insufficient to keep the molecules sliding over each other.
