The ice streams in Antarctica will be flowing rapidly due to basal sliding — so it is incorrect to say that all glaciers are flowing by internal deformation only.
The current flow speeds at the terminus are too fast to be caused solely by internal deformation of the ice, implying that an increase in basal sliding forced by additional meltwater production is the probable cause of the velocity increases.
Glacier - A mass of land ice that flows downhill under gravity (through internal deformation and / or sliding at the base) and is constrained by internal stress and friction at the base and sides.
