Hello. • 1. How was your spring break? • How do you plan on practicing our three goals in the following days? • Please bring your books for the remainder of this course!
Welcome Back What to expect for the next weeks.
Human Geography • Two questions Geographers strive to answer • Where- Where are people and activities found on Earth? • Why- Why are they found there?
1. Ratio • Ratio Scale- Fractional scale shows the numerical ratio between distances on the map and Earth’s surface. Example below…
2. Written Scale • Describes relationship between map and Earth distances in words. • Example below…
3. Graphic Scale • Use of symbols, usually bar line, used to show distance on Earths surface. • Example below….
II. Projection • Definition- Transferring locations on Earth’s surface to a flat map. • 4 types of distortions • Shape-Area appears more elongated or shorter than in reality • Distance-Distance between two points is disproportionate. • Relative size- Alters area to appear larger or smaller then they are in reality. • Direction-Direction from one place to another can be incorrect on map.
GPS – Global Positioning System Definition- Determines the precise position of areas on Earth • 3 Elements: • Numerous satellites (remote sensing) • Tracking stations (controls the satellites) • Receiver (used to pinpoint location
GIS – Geographic Information System) Definition- Computer system that can capture, store, analyze, and display geographic data • More accurate • Can show relationships between different kinds of information • http://
Density • Definition: How often something occurs in space. • High density=something occurs often Note: Large population does not always mean high density. • Low density= something occurs rarely • Kinds of density • Arithmetic density (including population density) • Physiological density • Agricultural density
Arithmetic Density • The total number of a certain object in an area • Often compares population in different countries • Myth: Large population means high population density
Physiological Density • The number of people per unit of land suitable for agriculture (farming). • A high physiological density may mean a country can’t grow enough food to feed its population
Agricultural Density • Number of farmers per unit of area suitable for agriculture • High agricultural density means that most people grow just enough to feed themselves and their families (subsistence farming)
