Natural regions are areas of the Earth that share similar physical characteristics, such as climate, vegetation, and landforms. These regions can be large, like continents, or smaller, like specific ecosystems. For example, the Amazon Rainforest is a natural region known for its dense forests and diverse wildlife, while the Sahara Desert is recognized for its arid climate and sandy landscapes. Understanding natural regions helps us appreciate the planet's biodiversity and the different environments that exist. Each region supports unique plants and animals, like the Great Barrier Reef in Australia, which is home to a variety of marine life. By studying these areas, we can better protect and conserve our natural world.
