The placing of rock armourstones at the foot of a cliff relies on several factors to protect the area behind. These are the slope of the front face of the structure, the voids within the structure itself and the weight of the individual blocks. If you imagine a boxing match when one of the contestants is hit full in the face the effect of the blow is much more than a "glancing " blow which slides off the opponents chin. This is the same with a rock strucure where the front slope shape means that the force of the wave attack is deflected and its impact is reduced. When you add to this the fact that a rock armour structure is full of voids between each individual piece of rock we can see that any wave energy is dissipated by the fact that the incoming wave passes into the voids and as it can expand into the void some of the pressure is released and the energy is lost. Imagine squirting a hose pipe into a sponge full of holes, the force of the water inside is much less. This loss of wave energy has two effects both in reducing the impact of the wave but also in preventing reflection of the wave when it hits the structure and it is this reflection which generally cause undercutting of more "solid" forms of structure such as the old Victorian vertical sea walls we see in many seaside resorts. For the above effects to happen it is vital that each of the individual blocks are of sufficient "size" that they are not picked up by the waves and tossed about into the cliff causing even more damage. The term "size" is a mixture of block weight and specific gravity of the rock piece and these two factors combined with the slope angle of the front face dictates the design of the structure required to withstand a particular wave height.
The cost of rock armor can vary depending on the type of rock, the size and thickness of the armor, and the location where it is being installed. Generally, expect to pay thousands to tens of thousands of dollars for rock armor installation to protect shorelines or structures from erosion. It is recommended to obtain quotes from different suppliers or contractors for accurate pricing.
Yes, rip rap and rock armor refer to the same thing - the use of large rocks or boulders to protect against erosion and wave action along coastlines or riverbanks. Rip rap is the term often used in North America, while rock armor is more common in Europe.
Sea cliffs: Steep vertical rock faces that are formed by the continuous erosive action of waves undercutting the base of coastal cliffs. Sea stacks: Tall pillars of rock that are isolated from the mainland due to erosion of softer rock material by waves. Sea caves: Hollowed-out openings in coastal cliffs or headlands created by wave action eroding softer rock along fault lines or joints. Wave-cut platforms: Flat, level areas of rock that are exposed at low tide, formed by the continual erosion of the base of cliffs by wave action.
Sea cliffs - steep rock formations created by the erosion of coastal areas by waves. Sea stacks - isolated pillars of rock formed when softer coastal rock erodes away, leaving harder rock formations behind. Wave-cut platforms - flat, rocky surfaces at the base of sea cliffs formed by the continual erosion of the cliff face by waves. Sea caves - hollow spaces within coastal cliffs carved out by the action of waves over time. Arch - natural rock formations with a hole through them formed by the erosion of coastal cliffs.
Cliffs can be protected from erosion by constructing seawalls, adding riprap or rock armour at the base, planting vegetation on the cliff face, and controlling surface water drainage to reduce erosion. Regular monitoring and maintenance are also important to ensure these measures remain effective in protecting the cliffs.

It depends on what kind of rock they are made of. Cliffs formed of igneous rock generally do not contain carbonates. Cliffs that have some limestone, marble, or dolomite do contain carbonates.
It needs armor to protect itself.
The cliffs and canyons of Starved Rock are made of an Ordivician age sandstone called St. Peter sandstone.
