A fragmented state has several noncontiguous pieces of territory. Archipelagos such as Philippines, Indonesia, and Fiji are examples of fragmented states. [1] A prorupted or protruded has an extension that protrudes from the main territory. [3] Thailand is an example of a prorupted state. [1] A perforated completely surrounds another state ...
Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically . Natural patterns include symmetries , trees , spirals , meanders , waves , foams , tessellations , cracks and stripes. [ 1 ]
The example of king crabs (family Lithodidae) evolving from hermit crabs has been particularly well studied, and evidence in their biology supports this theory. For example, most hermit crabs are asymmetrical , and fit well into spiral snail shells ; the abdomens of king crabs, even though they do not use snail shells for shelter, are also ...
In political geography, an enclave is a piece of land belonging to one country (or region etc.) that is totally surrounded by another country (or region). An exclave is a piece of land that is politically attached to a larger piece but not physically contiguous with it (connected to it) because they are completely separated by a surrounding foreign territory or territories.
The term phase is sometimes used as a synonym for state of matter, but it is possible for a single compound to form different phases that are in the same state of matter. For example, ice is the solid state of water, but there are multiple phases of ice with different crystal structures, which are formed at different pressures and temperatures.
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 ]
Ferromagnetism: A state of matter with spontaneous magnetization. Antiferromagnetism: A state of matter in which the neighboring spin are antiparallel with each other, and there is no net magnetization. Ferrimagnetism: A state in which local moments partially cancel. Altermagnetism: A state with zero net magnetization and spin-split electronic ...
The Northwest Angle in Minnesota, bordering Manitoba, Ontario, and Lake of the Woods. There are several exclaves between the United States and Canada, including the entire state of Alaska (though the state can still be accessed by sea from the United States, except the small settlement of Hyder, which is only accessible by road from British Columbia).
