Unit 1

Question 1

Reference maps show

Answer 1

Are informational. show boundaries and place names

Question 2

What do reference maps often display?

Answer 2

they often display physical and man-made features.

Question 3

Thematic maps show

Answer 3

thematic maps show density and distribution of quantitative data.

Question 4

Quantitative data vs. qualitative

Answer 4

quantitative data is number-based, countable, measurable
Qualitative data is opinion-based, descriptive

Question 5

Geospatial data

Answer 5

data that included information related to locations on Earth.

Question 6

5 ways to represent geospatial data

Answer 6

1) Choropleth maps
2)Dot maps/ distribution maps
3)Graduated symbol maps/ proportional
4)Isoline
5)Cartograms

Question 7

Choropleth maps

Answer 7

use colors and shading to show density, NOT distribution.

Question 8

Dot distribution maps

Answer 8

place a dot representing a value in its approximate location.

Question 9

Graduated symbol maps

Answer 9

feature symbols proportional in size to actual value of data. sometimes too cluttered and hard to differentiate symbol size.

Question 10

Isoline

Answer 10

Connect areas of equal value with lines. Often for weather maps, hard to interpret unless colors are used

Question 11

Cartograms

Answer 11

Distort appearance of places on the map to represent their value. (make countries with high population relative to size larger. )

Question 12

Absolute location

Answer 12

Quantitative measurement. Coordinates, exact distance

Question 13

Relative location

Answer 13

qualitative measurement. where something is compared to another place.

Question 14

elevation

Answer 14

topographical maps, isoline

Question 15

Map projection

Answer 15

taking anything that is spherical and displaying it on a flat surface. Earth is gonna be distorted in some way.

Question 16

Conformal projection

Answer 16

preserve shape but no size

Question 17

equal-area projections

Answer 17

distort oceans to preserve size of landmass not shapes

Question 18

Mercator projection

Answer 18

latitude and longitude lines meet at right angles. Preserves shape not size massively at higher latitudes. Used for navigation.

Question 19

Gall-peters projection

Answer 19

preserves size but not shape. appears opp. of mercator

Question 20

Robinson projection

Answer 20

preserves size and shape of continents but distorts polar areas. published atlases

Question 21

Goode’s Homolosine projection

Answer 21

interrupts projection and removes much of ocean to preserve size and shape of landmass. used for thematic maps.

Question 22

push factors vs. pull factors

Answer 22

push factors are why you leave pull factors why you migrate there.

Question 23

geographic features examples

Answer 23

Valleys.
Plains.
Deserts.
Seas. …
Wetlands.
Canals.
ect.
