Social Studies Unit 1

What is the name given to the parallel, 0° latitude?


Equator

What is the highest latitude you can measure from the Equator?



90°

What is the highest longitude you can measure from the Prime Meridian?
°

180°

Why are maps more practical than globes?


They are easier to carry and you can see specific locations

Why are maps not as accurate as a globe?


Because they make some places look bigger than they actually are

What is a graticule?


A grid system of parallels and meridians

What is the name given to the meridian, 0° longitude?


Prime Meridian

What is the BEST and most accurate model of Earth?


Globe

Describe map scale and list the 3 types.


Gives a relationship between the length measured on the map and the corresponding distance on the ground. Verbal scale, graphic scale, fractional scale

What is an isoline?


A thematic map that uses lines to connect points of equal value to depict variations in the data across space (elevation)

Describe how to construct an isoline on a map. (Use the word interpolate or estimate correctly.)


To construct an isoline, connect points of equal value and interpolate (estimate) the line’s position between known data points

What type of isolines are found on topographic maps?


Contour lines (lines that show elevation)

What information is provided on topographic maps?


Shows the elevation and shape of the land, along with natural and man-made features

Political map


It shows labels of human-created boundaries like states, countries, cities, and capitals

Physical map


A map that shows labels of natural features

Cartogram
Map

that shows sizes of countries not based on their land area, based on population and other stuff

Absolute location


The precise spot where something is according to a system

Relative location


The position of places in relation to other places or landmarks

The global positioning system is based on what information?


Satellite signals

Your phone uses GPS. What general term is used for your phone?


GPS receiver

What type of waves does radar use?


Radio

What type of waves does sonar use?


Sound

What type of waves does lidar use?


Light / laser

Describe a conformal map in terms of size and shape accuracy.


Impossible to depict true shape; usually greatly enlarges sizes in higher latitudes

Describe an equivalence map in terms of size and shape accuracy.


Avoids misleading impression of size; they must display disfigured shapes

Describe a compromise map in terms of size and shape accuracy.


Can only closely approximate both equivalence and conformality in maps of very small areas
