UNIT 1: Thinking Geographically Flashcards
(218 cards)
What is a map scale?
A map scale represents the relationship between distances on a map and actual distances on the ground.
What are large-scale maps?
Large-scale maps show a lot of detail and are used for city or street maps.
What are small-scale maps?
Small-scale maps cover a larger area but show less detail, such as world or regional maps.
What is a ratio scale?
A ratio scale is expressed as a ratio, such as 1:25,000, indicating the relationship between map distance and actual distance.
What is a written scale?
A written scale explains the relationship in words, such as ‘1 inch equals 1 mile’.
What is a graphic scale?
A graphic scale is a bar line marked on the map to show actual distance covered.
What is a projection in cartography?
A projection is a method of representing the curved surface of the Earth on a flat map.
What is the Mercator projection?
The Mercator projection preserves angles for navigation but distorts the size of land masses near the poles.
What is the Peters projection?
The Peters projection shows countries in their true relative size but distorts shapes and distances.
What is an equal-area projection?
An equal-area projection preserves the area of land masses but distorts shape and distance.
What is the Robinson projection?
The Robinson projection is a compromise projection that reduces distortions while maintaining visual appeal.
What is latitude?
Latitude measures the location of a place north or south of the equator, expressed in degrees.
What is longitude?
Longitude measures the location of a place east or west of the Prime Meridian, expressed in degrees.
What is a geographic grid?
The geographic grid is a system of intersecting lines that allows for the precise location of points on the Earth’s surface.
What is a meridian?
A meridian is an imaginary line running from the North Pole to the South Pole, used to measure longitude.
What is a parallel?
A parallel is a line of latitude that runs horizontally around the Earth, used to specify north-south position.
What is a graphic scale?
A graphic scale visually represents the relationship between distance on a map and actual distance on the ground.
What is the significance of map projections?
Map projections are essential for representing the Earth’s surface on flat maps, but they introduce distortions.
What is geographic data?
Geographic data is any data associated with a specific location on the Earth’s surface, including coordinates, names of places, terrain features, land use patterns, and population statistics.
What are examples of names of places?
Examples include cities (New York, London), towns (Millville, Maplewood), villages (Hogsmeade, Twin Peaks), regions (Southwest, Midwest), countries (United States, Canada), and natural features (Mount Everest, Grand Canyon).
What are terrain features?
Terrain features are natural features of the Earth’s surface, such as mountains, valleys, rivers, lakes, and oceans.
What are examples of mountains?
Examples include the Rocky Mountains, the Himalayas, and Mount Everest.
What are examples of valleys?
Examples include the Grand Canyon, the Shenandoah Valley, and the Rift Valley.
What are examples of rivers?
Examples include the Amazon, the Nile, and the Mississippi.
