Lesson 1.2 Geographers Tools

Question 1

What do maps show?

Answer 1

Map show the location of places landforms and bodies of water and where they are in relation to other parts of the Earth

Question 2

What are maps?

Answer 2

Maps are two dimensional graphic representations are selected parts of the Earth’s surface Distortion occurs as the earth’s surface is flattened to create the map

Question 3

What does a cartographer do?

Answer 3

Reduces distortion

Question 4

What is map projection?

Answer 4

A way of drawing the Earth’s surface that reduces Distortion caused by representing a round Earth on flat paper

Question 5

What does a topographic map show

Answer 5

A representation of natural and man-made features on Earth

Question 6

What do thematic Maps show?

Answer 6

Emphasize specific types of information

Ex: climate or population density

Question 7

What are navigational maps?

Answer 7

Pilots and sailors use navigational Maps

Question 8

What does surveying do?

Answer 8

What is observed, measured, and recorded from a specific area to be converted to gray image which is then used by cartographers to construct Maps

Question 9

What do satellites do?

Answer 9

Geographers rely heavily on satellites to provide Geographic data

Question 10

What is geographic information (GIS)

Answer 10

Stores information about the world in a digital database and has the ability to combine information from a variety of sources and display it in ways it allowed the user to visualize the use of space in different ways

Question 11

What is global positioning system (GPS)

Answer 11

Uses 30 satellites to beam information to Earth including the exact position, longitude, latitude, altitude, and time to help geographers visualize and display information for analysis

Question 12

What does a small scale show?

Answer 12

A small scale map shows a large area but without much detail. A small scale is used to see relative location in a region or between regions.

Question 13

What does a large scale map show?

Answer 13

A large scale map shows a small area with much more detail. A large scale is used to see relative location within a region.

Question 14

Latitude lines

Answer 14

Latitude lines are also called parallels because they run parallel to the equator North 90° and South 90°

Question 15

Longitude lines

Answer 15

Longitude lines are also called meridians because like the prime meridian, they run from pole to pole. 180° in West and 180° in East

Question 16

What is a planar (azimuthal) projection?

Answer 16

A projection on a flat surface. The azimuthal projection shows the Earth so that a line from the central point to any other point on the map gives the shortest distance between the two points. Size and shape are distorted.

Question 17

What are conical projections?

Answer 17

A projection onto a cone that shows shape fairly accurately but it distorts land masses at the edges of the map. They are often used to show landmasses that extend over large areas going EAST and WEST

Question 18

What are compromise projections?

Answer 18

A projection onto a cylinder that shows the entire Earth on one map

Question 19

What are the three types of compromise projections?

Answer 19

Mercator- the shapes of the continents are distorted at the poles and somewhat compressed near the equator

Question 20

What are the three types of compromise projections?

Answer 20

Homolosine- an interrupted a map because the oceans are divided this projection shows the accurate shapes and sizes of the landmasses the distance on the map are not correct

Question 21

What are three types of compromise projections?

Answer 21

Robinson- shows the entire Earth with nearly the truth sizes and shapes of the continents and oceans however the shapes of the landforms near the poles appear flat
