Explanation:
A world political map is a representation of the political divisions and boundaries of countries and territories around the world. It provides an overview of the political organization of the Earth's surface. The most commonly depicted feature on a world political map is political boundaries.

Political boundaries:
- Political boundaries are the lines that separate countries, states, provinces, and other administrative divisions.
- These boundaries are crucial in understanding the organization and structure of political entities globally.
- Political boundaries indicate the territorial limits of a country and the areas over which it has jurisdiction.
- They define the legal framework within which governments exercise their authority and establish their sovereignty.
- Political boundaries can change over time due to various factors such as historical events, territorial disputes, and diplomatic agreements.

Other features:
While political boundaries are the most common feature on a world political map, other features may also be depicted to provide additional information and context. Some of these features include:

- Mountain ranges: Mountain ranges are often represented on world political maps to show the physical geography and topography of the Earth. They can give an idea of the major landforms and natural barriers that exist between different regions.

- Rivers: Rivers are another feature that is commonly depicted on world political maps. They are important for understanding the hydrology and transportation networks of different regions. Rivers can also serve as natural boundaries between countries or states in some cases.

- Time zones: Time zones may also be included on a world political map to indicate the different standard times observed in different regions. This can help in understanding the global time differences and facilitate international communication and coordination.

While these features are important, political boundaries are the primary focus of a world political map as they provide the fundamental framework for understanding the political organization of the world. They play a crucial role in representing the distribution of power, governance, and international relations on a global scale.
