What kind of lava is so thick in consistency that it barley creeps along the ground?

The type of lava that is thick in consistency and barely creeps along the ground is known as "andesitic lava." This lava has a higher viscosity due to its composition, which includes higher silica content compared to basaltic lava. As a result, it flows slowly and can build up into steep-sided volcanic domes or plug formations. The thick nature of andesitic lava often leads to explosive volcanic activity when pressure builds up beneath the surface.
