Maps

Question 1

What are the characteristics of maps?

Answer 1

scale, symbols, and grids.

Question 2

How do geographers describe where things are?

Answer 2

use absolute location

Question 3

How does the longitude/latitude system work?

Answer 3

All lines of latitude measure either north or south from the 0-degree line of latitude (the equator). … The lines of longitude measure either east or west from the 0-degree line of longitude (the Prime Meridian).

Question 4

Meridians

Answer 4

Longitude is measured by imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians.

Question 5

Parallels Degrees

Answer 5

Parallels represent degrees of latitude, or how far a place is away from the equator. The equator’s latitude is 0 and the poles are 90 south and north.

Question 6

Properties of a Map

Answer 6

distance, direction, shape, and area

Question 7

International Date Line

Answer 7

passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth

Question 8

Time zones

Answer 8

The United States is divided into six time zones: Hawaii-Aleutian time, Alaska time, Pacific time, Mountain time, Central time and Eastern time.

Question 9

How wide is a time zone?

Answer 9

15 degrees

Question 10

Why are time zones not all the same size and shape?

Answer 10

They are based on longitude and defined by Earth’s rotation

Question 11

Cylindrical

Answer 11

cylindrical projection, in cartography, any of numerous map projections of the sphere on the surface of a cylinder that is then unrolled as a plane. Originally, this and other map projections were achieved by a systematic method of drawing the Earth’s meridians and latitudes on the flat surface.

Question 12

Mercator

Answer 12

Mercator is a conformal cylindrical map projection that was originally created to display accurate compass bearings for sea travel. An additional feature of this projection is that all shapes are accurate.

Question 13

Conic

Answer 13

A map projection in which the surface features of a globe are depicted as if projected onto a cone typically positioned so as to rest on the globe along a parallel

Question 14

polyconic

Answer 14

The name translates into “many cones,” and it is created by lining up an infinite number of cones along the central meridian.

Question 15

Area / Equal-area

Answer 15

preserve area measure, generally distorting shapes in order to do that

Question 16

Shape / Conformal

Answer 16

A map that preserves shape

Question 17

Distance / Equidistant

Answer 17

A projection that maintains scale along one or more lines

Question 18

Direction / Azimuthal

Answer 18

a horizontal angle measured clockwise from a north base line or meridian

Question 19

Mercator Projections

Answer 19

a geographical chart where the spherical globe is flattened into a two-dimensional map

Question 20

Miller Cylindrical

Answer 20

The Miller cylindrical projection is a modified Mercator projection, proposed by Osborn Maitland Miller in 1942.

Question 21

Robinson Projection

Answer 21

map projection of a world map which shows the entire world at once

Question 22

What are the best uses for the basic types of projections?

Answer 22

they are azimuthal, conic, Mercator cylindrical, and Robinson cylindrical due to their conformity

Question 23

3 ways Scale represented on maps

Answer 23

There are three primary ways to indicate scale on a map: a representative fraction (e.g., 1:24,000), a verbal scale (e.g., “One inch to the mile”), or a graphic scale bar.

Question 24

Large Scale vs Small Scale Maps

Answer 24

Large scale maps show a smaller amount of area with a greater amount of detail. … Large scale maps are typically used to show neighborhoods, a localize area, small towns, etc. Small scale maps show a larger geographic area with few details on them.

Question 25

Formal Regions

Answer 25

Formal regions are uniform or homogeneous areas where everyone in that region shares common attributes or traits like language, climate or political system.

Question 26

Functional Regions

Answer 26

A functional region is a region that serves a function. Places within in an area are linked together through a common factor. For example, a city and its surrounding suburbs creates a functional region. People generally move to the suburbs if they have a job in the city.

Question 27

Perceptual Regions

Answer 27

can also be an idea of a person’s mental map. It can be viewed as how people think about or perceive a region based on factors that may not reflect the truth, such as the Bible Belt or Hillbilly region.

Question 28

Quantity Maps

Answer 28

A GIS quantity map is color-coded, but uses different shades of the same color to show the variety in quantities of something depicted on the map.

Question 29

Cartogram Maps

Answer 29

A cartogram is a thematic map of a set of features, in which their geographic size is altered to be directly proportional to a selected ratio-level variable, such as travel time, population, or GNP.
