Geoconservation is the practice of recognising, protecting and managing sites and landscapes which have value for their geology or geomorphology. [1] [2] The conservation of these geological sites is through government agencies and local geological societies in areas such as Europe and Africa.
Uplift can therefore lead to a sequence of marine terraces at a few distinct elevations along the coast. Although these surfaces formed at sea level maxima during interglacial periods, the landforms are preserved solely due to tectonic uplift.
The effectiveness of protected areas to protect biodiversity can be estimated by comparing population changes over time. Such an analysis found that the abundance of 2,239 terrestrial vertebrate populations changed at slower rate in protected areas. On average, vertebrate populations declined five times more slowly within protected areas (−0. ...
Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type.Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains ...
A seawall (or sea wall) is a form of coastal defense constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation, and leisure activities from the action of tides, waves, or tsunamis. [1]

Walls of concrete and masonry are used to protect a settlement against erosion or flooding. They are typically about 3–5 metres (10–16 ft) high. Older-style vertical seawalls reflected all the energy of the waves back out to sea, and for this purpose were often given recurved crest walls which increased local turbulence, and thus increased ...
