Tombolo near Karystos, Euboea, Greece Tombolo contrasted with other coastal landforms.. A tombolo is a sandy or shingle isthmus.A tombolo, from the Italian tombolo, meaning 'pillow' or 'cushion', and sometimes translated incorrectly as ayre (an ayre is a shingle beach of any kind), is a deposition landform by which an island becomes attached to the mainland by a narrow piece of land such as a ...
Wave attenuators consist of concrete elements placed horizontally one foot under the free surface, positioned along a line parallel to the coast. Wave attenuators have four slabs facing the sea, one vertical slab, and two slabs facing the land; each slab is separated from the next by a space of 200 millimetres (7.9 in).
Shut-in – Type of rock formation found in Ozarks streams; Side valley – Valley with a tributary to a larger river; Sinkhole – Geologically-formed topological depression; Sound – A long, relatively wide body of water, connecting two larger bodies of water; Spit – Coastal bar or beach landform deposited by longshore drift
The sandy isthmus or tombolo "The Neck" connects North and South Bruny Island in Tasmania, Australia. An isthmus (/ ˈ ɪ s m ə s, ˈ ɪ s θ m ə s /; [1] pl.: isthmuses or isthmi) [2] is a narrow piece of land connecting two larger areas across an expanse of water by which they are otherwise separated.

An example of this type of cuspate foreland is the one found at Dungeness along the southern coast of Britain. [6] This cuspate foreland has formed as a result of the merging of SW waves from the English Channel, and waves from the east from the Strait of Dover. [ 4 ]
Map showing two examples of how coves form. The rock types are those of Lulworth Cove. In example A, a river breaks through the resistant chalk back rock and limestone, leaving the weak clays to be rapidly eroded. In example B, the sea breaks through the limestone, perhaps by forming a cave, and then erodes the clay away.
Compatibility controls the partitioning of different elements during melting. The compatibility of an element in a rock is a weighted average of its compatibility in each of the minerals present. By contrast, an incompatible element is one that is least stable within its crystal structure.
In model theory, a branch of mathematical logic, the diagram of a structure is a simple but powerful concept for proving useful properties of a theory, for example the amalgamation property and the joint embedding property, among others.
