This document appears to be from a geography textbook and covers several key concepts:
- Geography studies both physical features of the Earth as well as human activities and interactions with the environment.
- Geographers use tools like maps and measurements to describe locations, regions, ecosystems, and relationships between places.
- Locations can be described in absolute or relative terms, and regions include formal, functional, and perceptual types based on shared characteristics.
- Physical systems and human activities both shape the Earth's surface and environments over time through migration, trade, and adaptation to barriers.
