1.1 What is Geography?

Geography is the study of Earth's landscapes, peoples, and environments. It focuses on spatial relationships and patterns, examining how physical and human elements interact across space and time. This field uses tools like GIS and remote sensing to analyze connections between different locations and features.

Geographers explore key questions like "Where is it located?" and "Why is it there?" They investigate how places change over time, interact with each other, and form patterns. This approach helps address global challenges like climate change, resource management, and urbanization.
