Is rock in the crust able to move around more easily than the rock in the lower mantle?
No it's the other way round. Rock in the mantle is hotter, nearer to its melting point (though it's still solid) and so can move around quite easily. Rock in the crust is much cooler, like frozen ice and so it is much harder to move around.
