Unit I Review – Chapters 1 -8
30. Map projection – when the round features of the globe are transferred to a flat surface.
31. Mental map – map in our mind of places we know
32. Mercator Projection – the most common map projection but it distortes true size of
landmasses.
33. Pie graph – common graph that uses sections of a circle to illustrate value
34. Population density – figure calculated by dividing the population of a region by a region’s area
35. Prime meridian – line of longitude on maps or globes that joins the North and South Poles and
runs through Greenwich, England.
36. Proportional area graph – type of graph that can be produced in many shapes, frequently circles
37. Radar – in remote sensing, rador sensors send out microwaves to the Earth’s surface and use
the microwaves reflected back to create image of human objects and natural features on the
Earth’s surface
38. Remote sensing - science of acquiring information about the earth’s surface without being in
contact with it.
39. Representative fraction scale – scale on a map given as a ratio of distance on the map to
distance on the ground, such as 1:50 000
40. Satellite – manufactured object that is launched by a rocket and circles the Earth
41. Scale – measurement on a map that represents an actual distance on the Earth’s surface
42. Small-scale map – map that shows a small amount of detail of a large area
43. Stacked bar graph –very much like bar graph, with one important difference: while each bar
in a simple bar graph represents one value, a stacked bar can be used to represent several
closely related values
44. Standard time –every place within a time zone has the same time, which is referred to as
standard time
45. Stereo pair - pair of aerial photographs that when looked at through a stereoscope, show 3dimensional
image
46. Thematic map - map containing information on only one particular topic
47. Time zone – division of the Earth’s surface, usually extending across 15 degrees longtitude,
that establishes a uniform time
48. Topographic map – large-scale map showing both natural and human-made features
49. Topography – natural and human features of the landscape
50. Weather – combination of temperature, precipitation, cloud cover, and winds experienced daily
51. Winkel Tripel projection – best map projection for providing a balance between size and shape
52. X / y scattergraph - simple and useful graphs showing relationships between two sets of data
Review/Sample Questions
1. The main problem with the Mercator Projection in class is distorts size and shapes of
large objects like landmasses
2. Which map is used to show elevation? Topographic
3. When the features of a globe are transferred onto a flat surface, it is called: map projection
4. Thematic maps show information from one particular topic.
