Natural Regions: Defining Earth's Physical Landscapes

What Are Natural Regions?

Natural regions are areas of the Earth defined by shared physical characteristics—climate, soil, vegetation, landforms, and hydrology. They provide a framework for understanding global environmental patterns.

Examples

• Tropical Rainforests: Near equator; high heat, heavy rain, dense biodiversity.
• Temperate Forests: Mid-latitudes; moderate climate, deciduous/coniferous trees.
• Deserts: Arid; sparse vegetation, extreme temperature swings.
• Grasslands: Prairies, steppes, savannas; dominated by grasses.
• Tundra: Arctic/alpine; permafrost, low-growing vegetation.

These regions help scientists study species distribution, ecosystem services, and human impacts.
