Explanation
A border is a line or area that separates two countries, states, or places. It shows where one place ends and another begins. Borders can be natural, like rivers or mountains, or made by people, like fences or walls. Sometimes crossing a border means you need a passport or permission. Borders help keep places organised and safe.
