What is the difference between a Natural boundary and a political boundary? Give examples of each.
A natural boundary something which separates things or places and is caused by geographic or physical items. A political boundary is a line on a map that separates countries from each other or states within each country.
Yes, you're right. Natural boundaries include the Rio Grande River between the U.S. and Mexico. Also -- the St. Lawrence River between the U.S. and Canada and the Mississippi River between many pairs of states.
Political boundaries are usually straight lines.
