Here's why:

* Physical maps focus on the Earth's natural features. This includes:

* Landforms: Mountains, valleys, plateaus, plains

* Water bodies: Rivers, lakes, oceans, seas

* Vegetation: Forests, deserts, grasslands

* Political maps focus on human-made boundaries, like countries, states, and cities.

While some political maps may include simple symbols for major rivers or mountains, their primary focus is on human-made divisions.
