Latitude/Longitude Pg. 8

One of the Greeks’ primary contributions to oceanography and seafaring is the latitude/longitude system.

Latitude lines run east-west and Longitude lines run north-south.

They are numbered in degrees, then minutes and seconds like time. (1degree=1/360 of earth)

Mapping Pg. 9• Cartography- the science of map making.• Cartographers are scientists who make maps.

They collect data from a lot of sources•Remote sensing—gathering and analyzing information about an object without physically touching it.

How do we make maps?

• Map projections –a flat map that represents the curved surface of the earth.

• The problem is that it is hard to transfer a curved surface to a flat format.

• Distortions always happen in map projections.

Map Projections

1. Cylindrical• A cylindrical projection is

the most common type of map. Imagine placing a movie screen around a globe in a cylinder shape. The projection that results is shown in this image. Near the equator there is very little distortion. But, the closer you get to the poles, the more distorted the map is. In this ex. Greenland appears to be many times larger than it really is.

2. Conic• A conic projection map

is created by placing a cone shaped screen on a globe. The resulting projection is more accurate than the cylindrical projection map discussed above. However, the further we travel down the map, the more distorted and less accurate the map becomes.

3. Planar/Azimuthal• A plane projection

is created by placing an imaginary screen directly above or below a globe. The image that would result is called a plane projection. This type of map projection is not commonly used.

Attach map projections in notebook

Parts of a map:• 1. Compass directions

(compass rose)• 2. Legend(key)=explanation of

symbols • 3. Scale(the relationship

between the distance on the map and the actual distance)

Types of maps: 1. Road maps

2. Weather maps

3. Satellite maps

4. Geologic maps- rocks, faults and folds

5. Topographic Maps

model is a topographic map? Explain.

Topography Pg. 11Topographic Maps-show the surface shape(topography) of the land.–Uses lines called contour lines to connect

areas of equal elevation(height above sea level).• Isogram-line on a map that represents

constant or equal values.

– Contour interval-the difference in elevation between contour lines.

– Relief-the difference in elevation between the highest and lowest point on the map.

•

• lines pointing inward indicate a depression = decrease in elevation= like a pit or crater!

• What is the contour interval?• What is the relief?

Topographic Model Lab

• Need:– Model box– Washable marker– Piece of paper– Ruler– Water

Topo Map Model• Place the clear plastic lid on the box containing the

volcano model.• Using the marker and ruler, make marks at 1 cm intervals

on the outside of the box. Label the marks in cm’s(1cm, 2cm, etc.) up to 7cm.

• Fill the box up to the 1 cm mark with water poured in through the opening in the lid corner.

• On the lid, draw the line created by the water touching the volcano.

• Repeat for the 2cm, 3cm and the other marks up to 7cm.• Copy the map you made on the model lid on your

notebook page. Make sure you add elevation labels on each line and show depressions where appropriate.

Analysis Questions

1. What are the lines you just drew called?2. What is the contour interval of this map?3. What is the relief of this map?4. How did you represent the crater of the

volcano on your map?5. As the slope on the volcano gets steeper,

what happens to the distance between the contour lines?

• Create 2 circle maps—1 for the Prime Meridian and one for the International Date Line. As you read the following slides, fill in 5 facts for each topic.

Prime Meridian

Interna-tional

Date Line

The Prime Meridian is the meridian with a longitude of 0°. It was adopted officially in 1884 as a line from which longitude east and west are measured and as a basis forstandardized time zones. It passes through Greenwich, England, home of the Royal Greenwich Observatory. The Observatory was founded in 1675 and closed except as a museum in 1998. The prime meridian, together with its opposite meridian(the International Date Line at 180°) divide the Earth into the Eastern and Western Hemispheres.

The International Date Line is the imaginary line on the Earth that separates two consecutive calendar days. That is the date in the Eastern hemisphere, to the left of the line, is always one day ahead of the date in the Western hemisphere. Without the International Date Line travelers going westward would discover that when they returned home, one day more than they thought had passed, even though they had kept careful tally of the days. Likewise, a person traveling eastward would find that one fewer days had elapsed than he had recorded.

The International Date Line can be anywhere on the globe. But it is most convenient to be 180° away from the Prime Meridian that goes through Greenwich, England. It also is fortunate that this area is covered, mainly, by empty ocean. However, there have always been zigs and zags in it to allow for local circumstances.

?? How many time zones to go around the globe?• There are 24 time zones – 1 for each hour of
