Because it is large.
Geographers divide the earth using hemispheres.

Europe and Asia
The division of continents is largely based on tectonic plate boundaries and geography. Factors like the separation of land masses by oceans, the location of mountain ranges, and historical contexts have also influenced how continents were divided by geographers. Additionally, cultural, political, and economic considerations have played a role in the delineation of continent boundaries.

The Earth can be divided into physical regions based on continents, oceans, climate zones, landforms (such as mountains, plains, and deserts), and vegetation types. These divisions help geographers and scientists understand the diversity of the Earth's physical features and environments.

Geographers divide Latin America into three main regions: Central America, the Caribbean, and South America. Each region has its own unique cultural, historical, and geographical characteristics.
A.Continental regions can be very complex and difficult to study as a whole. B.Some nations on a continent do not allow researchers to visit. C.Certain regions of continents are not interesting to study. D.Some regions of continents do not have a large enough population for studies.
Longitude and Lattitude lines are often used on maps to divide and subsequently locate locations.
