In geology, a dike or dyke is a sheet of rock that is formed in a fracture of a pre-existing rock body. Dikes can be either magmatic or sedimentary in origin. Magmatic dikes form when magma flows into a crack then solidifies as a sheet intrusion, either cutting across layers of rock or through a contiguous mass of rock.
Urk was then and is still today a fishing community and it served as a natural construction-island for both dikes as well as a base of operations for the later exploitation of the polder. Both ceased to be islands: Urk on 3 October 1939, when the dike reaching from Lemmer was closed and Schokland when the surrounding water was consequently drained.

[11] In 1941 work for this project started; about 2 km of a dike north of Marken was built. It would have had an area of nearly 600 km 2. But the German occupation stopped the project.
The major contributors in later dike building were the monasteries. As the largest landowners they had the organization, resources and manpower to undertake the large construction. By 1250 most dikes had been connected into a continuous sea defense. The next step was to move the dikes ever-more seawards.

Constructed between 1954 and 1997, the works consist of dams , sluices , locks , dykes , levees , and storm surge barriers located in the provinces ...

The three types of polder are: Land reclaimed from a body of water, such as a lake or the seabed; Flood plains separated from the sea or river by a dike
