This document provides an overview of key concepts in geography, including the five themes of geography: location, place, human-environment interaction, movement, and regions. It discusses geography as the study of the Earth's surface and the relationship between people and their environment. As an example, it summarizes the settlement of Kenosha, WI, explaining that pioneers found desirable rich farmland and a port/harbor for fishing and trading. It notes the Potawatomi originally fished in the area and that the name Kenosha is derived from their word for pike fish. Tools used by modern geographers like satellite images, GPS, and GIS are also outlined.
