APHG Unit 1 Flashcards
Human Geography
The study of why something exists in a certain location, including social and economic processes.
Physical Geography
Focuses on natural landscapes, such as mountains, rivers, and climate.
Cartography
The science of map-making.
Reference Maps
Accurate maps used for navigation or location.
Myth of Continents
The misconception of continent sizes, such as Europe appearing larger due to Eurocentric map projections.
Equator
The 0° latitude line dividing Earth into the Northern and Southern Hemispheres.
Prime Meridian
The 0° longitude line running through Greenwich, UK, dividing the Eastern and Western Hemispheres.
International Date Line
A line roughly along the 180° meridian where the calendar date changes.
Time Zones
24 divisions of the Earth’s rotation, each representing an hour difference.
Projection
The method of representing Earth’s curved surface on a flat map.
Distortion
Alterations in shape, distance, area, or direction due to map projection
Mercator
Distorts size near the poles but preserves direction, often used for navigation.
Robinson
Distorts everything, but in low levels. Reduces the distortion of land masses as they near the poles.
Molleweide
Better for equal AREA. Shape & Direction are distorted
Winkel Tripel (National Geographic Standard)
Good for minimizing 3 kinds of distortion:
area, direction, and distance
Azimuthal
Displays one hemisphere from a central point, maintaining accurate distance from the center.
Interrupted
Maps that break apart oceans to minimize distortion on landmasses.
Dot Maps
Use dots to represent quantities; more dots indicate higher frequency.
The “Ghost Map” (John Snow)
A famous dot map used to trace the source of a cholera outbreak in London.
Choropleth Maps
Use colors or shading to represent data values across areas
Proportional Symbol Maps
Use symbols of different sizes to represent data values.
Cartograms
Adjust the size of areas to reflect a variable, such as population.
Isolene Maps
Use lines to connect areas of equal value, such as elevation or temperature.
Mental Maps
Personal perceptions of the geography around us.
Activity Spaces
Areas where people routinely travel as part of their daily activities.
Terra Incognita
Unknown or unexplored regions.
Generalized Maps
Maps that simplify data to show broad patterns
GIS (Geographic Information Systems)
A computer system for capturing, storing, analyzing, and displaying geographic data.
GPS (Global Positioning System)
A satellite-based navigation system.
Remote Sensing
The collection of data about Earth’s surface from satellites or aircraft
Geocaching
A recreational activity where participants use GPS to hide and seek containers, called “geocaches.”
Large Scale
small area with more detail
