Introduction to Basic Geography Concepts

A boundary refers to the border of a country, usually demarcated by physical features or agreed-upon markers. It is the defining line that separates one nation from another.

A continent is defined as a large, continuous landmass surrounded by water on multiple sides. It is typically made up of various countries and has distinct geological features.

A country refers to a specific land region that is governed by a single government. It is not to be confused with a continent, food item, or currency.

The equator is an imaginary line that divides the Earth into the Northern Hemisphere and the Southern Hemisphere, located at 0 degrees latitude.

Geography is the study of physical features of the Earth's surface, as well as the processes that shape them, the interactions between the environment and humans, and the patterns and distribution of human populations.

Headwaters refer to the source or starting point of a river where water first emerges.

Latitude measures the north-south position of a point on the Earth's surface relative to the equator, with 0 degrees latitude being the equator and 90 degrees latitude being the North Pole and -90 degrees latitude being the South Pole.

Longitude is a geographical coordinate that specifies the east-west position of a point on the Earth's surface.

The prime meridian is the line of 0 degrees longitude that runs through Greenwich, England. It is used as the starting point for measuring longitude around the world.

A tributary is a smaller river that joins a larger river or body of water, contributing to its flow.
