World maps are visual representations of the Earth's surface, showing continents, countries, and oceans. They help people understand geography by providing a way to see the relationships between different places. Maps can vary in style, including political maps that highlight borders and physical maps that showcase natural features like mountains and rivers. There are different types of world maps, such as Mercator projection and Robinson projection, each with its own advantages and disadvantages. World maps are essential tools for education, navigation, and planning, making it easier for individuals to explore and learn about the planet.
