By comparison: They're soft and flexible most of the time, but if you hit them hard they instantly lock solid, dissipating impact energy by spreading it over a much larger surface and absorbing it at the same time. Surtseyan Submarine Subglacial.

Most magma chambers sit far beneath the surface of the Earth. The density of the atmosphere varies seasonally, as winter forces carbon dioxide to freeze out of the Martian air. Hit it or try to move it more suddenly and the chains don't have time to rearrange themselves properly. A cutaway showing Earth's layers.
