Answer:
A natural boundary would be that boundary caused by a river, mountain range, ocean, or lake or some other geographic, physical item.A political boundary is one that is a line on a map. ... A political map focuses on boundaries between entities, like countries, states or counties.
Explanation:
Political boundaries are the dividing lines between countries, states, provinces, counties, and cities. These lines, more often called borders, are created by people to separate areas governed by different groups. Sometimes, political boundaries follow physical boundaries, but most of the time you can’t see them. Most maps show political boundaries.
Political boundaries change over time through wars, treaties, and trade. After World War II, the map of Europe was almost completely redrawn. Germany’s eastern border was moved farther west, and the country itself was later divided into East and West Germany.
The most obvious type of boundary is a physical boundary. A physical boundary is a naturally occurring barrier between two areas. Rivers, mountain ranges, oceans, and deserts can all serve as physical boundaries. Many times, political boundaries between countries or states form along physical boundaries. For example, the boundary between France and Spain follows the peaks of the Pyrenees mountains, while the Alps separate France from Italy.
Most common Physical boundaries are made of:
Rivers
The Earth’s shell, or crust, is made of thick slabs of rock called tectonic plates. There are seven major tectonic plates and many smaller ones. These plates are constantly moving.
Ocean/Sea
Deserts
Mountains
