Messinian salinity crisis
The Messinian salinity crisis (also referred to as the Messinian event, and in its latest stage as the Lago Mare event) was a geological event during which the Mediterranean Sea went into a cycle of partial or nearly complete desiccation (drying-up) throughout the latter part of the Messinian age of the Miocene epoch, from 5.96 to 5.33 Ma (million years ago).

Thalweg
In geography, hydrography, and fluvial geomorphology, a thalweg or talweg is the line or curve of lowest elevation within a valley or watercourse.
Till
Closeup of glacial till. Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is diagnostic of till. Glacial till with tufts of grass Till or glacial till is unsorted glacial sediment. Overdeepening and till are Glaciology.

A tunnel valley is a U-shaped valley originally cut under the glacial ice near the margin of continental ice sheets such as that now covering Antarctica and formerly covering portions of all continents during past glacial ages. Overdeepening and tunnel valley are glacial erosion landforms and Glaciology.

Valley
A valley is an elongated low area often running between hills or mountains, which typically contains a river or stream running from one end to the other.
