What does 'situation' describe in geography?

A place’s interrelatedness with other places.

How is distance considered in geography?

In both absolute (measured units) and relative (perceived, functional) terms.

Define linear absolute distance.

The straight-line distance between two places measured in units such as miles or kilometers.

What does the distance-decay (gravity) concept state?

Interaction between two places declines as the distance between them increases.

State Tobler’s First Law of Geography.

All places are interrelated, but nearer places are more related than farther ones.

What is meant by the 'friction of distance'?

The effect of distance increasing the cost, effort, or time required for interaction between two points.

Explain space-time compression.

The reduction in time and relative distance required to connect two places, often due to advances in technology or transportation.

Give two technologies that can reduce relative distance.

Modern transportation modes (e.g., high-speed rail, airplanes) and the internet.

What is human-environment interaction?

The reciprocal relationship in which humans affect the environment and the environment influences human activities.

Define a central place.

Any node of human activity that commonly serves as a center of economic exchange.

Who developed Central Place Theory and in what decade?

German geographer Walter Christaller in the 1930s.

What geometric pattern represents market areas in Central Place Theory?

Hexagonal market areas that can overlap at different scales.

What do core-periphery relationships depict?

Contrasts in regional, cultural, economic, political, and environmental phenomena between a dominant core and its surrounding periphery.

What is the Central Business District (CBD)?

The core of an urban landscape, typically the primary area of commerce and economic activity.

Must the core be at the exact geographic center of its periphery?

No; the core’s influence defines it, not its geometric position.
