Natural boundaries are Coastlines, mountain ranges, lakes, rivers, gulfs, canyons, desert wastelands... basically, a part of the earth that is considered by most to be uninhabitable.
Political boundaries are the borders that are represented on maps by all the other lines besides natural boundaries and latitude/longitude indicators (although many political boundaries are natural boundaries and parts of lines of latitude and longitude). They are the boundaries between nations and between national subdivisions.
A natural border could be a river, sea or mountain range. Political borders are simply arbitrary lines drawn on a map.
The Pyreneesis a range of mountains in southwest Europe that forms a natural border between France and Spain.
Pennsylvania is bordered on all sides by state boundaries, which are all imaginary political boundaries between states. One boundary is purely political, the Mason Dixon line, with Maryland. One physical is the Delaware River, with New Jersey. Another physical boundary on the northwest corner is Lake Erie, both a physical and 'imaginary' political boundary between the US and Canada. How you can tell is to look for physical indicators---oceans, other water (large lakes, large rivers, places with many ports), or mountains that cut through an area or territory. These do not always mean a border--for example, the Applachian Mountains were not used as a state border in Pennsylvania--but often these physical indicators do make a border.
The border
A natural boundary is a boundary that is viewed from a physical factor like a mountain, river, or other land form/waterway. A political boundary is a boundary that is man made or decided by people. For example the state border is a political boundary.
A natural boundary is a boundary that is defined by natural features, such as a strait, a mountain range etc. A physical boundary is can be an imaginary boundary that is drawn on a map, which is not shown in real life, something like a political boundary.

A physical boundary is a natural feature of earth which can cause people or other organisms to esist differently depending on its placement. An example is the Appalachian Mountain Range, which caused a slower flow of American expansionism to the west than if the mountains had not been there. A political boundary is one drawn by people, such as the border of a country or a state, to define codes of behavior and law among humans. An example is the USA/Canada border which separates the two countries. Although political boundaries can occur near physical boundaries, one is not a type of the other and they can exist independently.
