It depends, as there are different kinds of dike.
One kind of dike, which may also be called a levee is a slope or wall along the banks of a stream or other body of water that holds it back, preventing or limitng flooding. These may be man-made or can form by the natural deposition of sediments.
Another kind of dike releates to igneous geology. This kind of dike forms when magma, or molten rock intrudes through rock, cutting across the rock layers, often vertically, as opposed to a sill, which forms between and parallell to the layers.
Many dikes form when magma from a large magma chamber invades fractures in the surrounding rocks.
Dikes are igneous rocks that form when magma intrudes into existing rock layers and then hardens. Sills are produced in much the same way but forms parallel to the rocky layers.
A dyke is formed when magma or lava spreads itself horizontally acrooss existing rocks or layers and then hardens.
To reclaim lanf from the sea by holding back the water
By piling up earth and rocks to build an earthen dam.
Igneous rock makes dikes and sills. Basalt or Diabese Dikes are actually usually composed of dolerite.
dikes sills and volcanic necks all have something to do with volcanoes
because they prevent flood from coming to them they are safe

Dikes and siills
The Netherlands (The Dutch built the dikes):-)
Dikes and sills are intrusions.
Netherlands invented Dikes & Windmills
They needed dikes to control flooding.
Dikes are walls, or 'levees ' to stop rivers flooding.
Igneous rock makes dikes and sills. Basalt or Diabese Dikes are actually usually composed of dolerite.
Dikes were used in china and all over the world for controlling floods

Magma rises from the earth to form dikes and sills
Dikes and levees prevent flooding by forming a barrier against rising waters.
The Netherlands is known as "the land of dikes" because it has a extensive system of dikes and levees to protect its low-lying land from flooding. The country has been using dikes for centuries to reclaim land from the sea and manage water levels.
Dikes are built by engineers and construction workers to prevent flooding by controlling the flow of water in rivers, lakes, and coastal areas. The construction of dikes requires careful planning, engineering expertise, and maintenance to ensure they remain stable and effective in protecting against flooding.
