Unit 1- This is geography Flashcards
The 5 concepts geographers use are:
Place, region, scale, space, and connections.
Maps can be used as (2 tools)
Reference tools and communication tools
Maps used as reference tools help us…?
find the shortest route between to places and not get list.
Maps used as communication tools help us…?
depict the distribution of human activities or physical features
Map scale-
The relationship of a feature’s size on a map to its real size on Earth
Three types of map scale-
Ratio, written, and graphic
A line of latitude is a parallel or median?
Parallel
A line of longitude is a parallel or median?
Median
How many time zones are there?
24
What is the universally accepted standard time? What median is it located at?
GMT, the Prime Meridian (0 degrees W)
GIScience-
Analysis of data about Earth acquired through satellites or other electronic information.
What are the three GIScience tools geographers use?
GPS, GiS, and remote sensing.
Define GPS.
GPS (global positioning system) is a system that determines the precise position of something on Earth.
Define GIS.
GIS (geographic information system) captures, stores, queries, and displays geographic data.
Define remote sensing.
The acquisition of data about Earth’s surface from a satellite orbiting Earth.
Four different maps get combined into one map showing the characteristics of all four. What geographic tool was used?
GIS
What is map projection?
Transferring locations on Earth’s surface to a flat map
What are the four types of map distortion?
Shape, distance, relative size, and direction.
Define shape distortion.
Appears more elongated
Define distance distortion.
The distance between two points changes.
Define relative size distortion.
The proportion of the size of two locations changes.
A map is in an oval shape with the top and bottom elongated. It contains significant relative size distortion. What map is this?
A Robinson Projection
A map is rectangular. There is very little relative size distortion, and there is a lot of space allocated to land. What map is this?
A Mercator Projection
What are the four ways geographers identify location?
Toponym (name), site, situation, and mathematical location (latitude/longitude)
