What is the difference between a nation, state and a country? Give an example of each

A state is a territory with its own institutions and populations.

A sovereign state is a state with its own institutions and populations that has a permanent population, territory, and government. It must also have the right and capacity to make treaties and other agreements with other states.

A nation is a large group of people who inhabit a specific territory and are connected by history, culture, or another commonality.

A nation-state is a cultural group (a nation) that is also a state (and may, in addition, be a sovereign state).

Texas’ gulf coastal plains are the western extension of the coastal plain extending from the atlantic ocean to beyond the rio grande. its characteristic rolling to hilly surface covered with a heavy growth of pine and hardwoods extends into east texas. in the increasingly arid west, however, its forests become secondary in nature, consisting largely of post oaks and, farther west, prairies and brushlands.
