APHUG 1.4

Flashcards that review key spatial pattern terminology, land-survey systems, density measures, and diffusion basics from the lecture notes.

What does the term "cluster" refer to in spatial analysis?

A grouping of things closely together on Earth's surface.

When clustering happens deliberately around a central point or economic growth pole, what is it called?

Agglomeration.

What kind of spatial pattern shows no rhyme or reason in its distribution?

A random pattern.

How do we describe objects that are normally ordered but appear dispersed?

They are described as scattered.

If a spatial pattern forms a straight line, what term is used?

Linear pattern.

Which term describes a wavy, snake-like spatial pattern?

Sinous pattern.

Why are land‐survey patterns important in geography?

They shape property lines and the political boundaries of states and provinces.

Before the 1830s, what land-survey system used natural landscape features to divide land?

The metes-and-bounds system.

Which land-survey system is based on rectilinear townships and ranges using lines of latitude and longitude?

The township-and-range survey system.

What characterizes a long-lot land-survey pattern?

Narrow frontage along a road or waterway with a very long, thin lot extending behind.

How is arithmetic density calculated?

Number of things per square unit of distance (e.g., people per square kilometer).

What does physiological density measure?

Number of people per square unit of arable (farmable) land.

What does agricultural density specifically measure?

Number of farmers per square unit of arable land.

In diffusion studies, what is a "hearth"?

The point of origin or place of innovation from which something spreads.

What general term describes the ways human phenomena spread across Earth’s surface?

Diffusion patterns.
