What else can be solid and flow like the asthenosphere?

Materials like certain types of lava, some types of salt, and even certain polymers can behave like the asthenosphere, exhibiting both solid and fluid characteristics. These materials can flow under pressure over time, displaying a property known as "viscoelasticity." Similar to the asthenosphere, they can maintain a solid structure while allowing for slow movement. Additionally, geological features like glaciers also exhibit solid-like behavior while flowing slowly under their own weight.
