1 Mapping Our World Section. and Longitude Skim Section of your text. Write three questions that come to mind from reading the headings and the illustration captions.. Responses may include questions about latitude,. longitude, and time zones.. New cartography Use your text to define the following term. the science of mapmaking Use the terms to label the figure below. equator line of latitude line of longitude prime meridian International Line 0 0 Academic parallel Define the following term. lines that lie in a common plane and do not intersect Section. and Longitude

2 Section. and Longitude (continued) Use with pages. Organize information about latitude by completing this graphic organizer. Use Figure - and other information in your text. They run parallel to the equator. Distances are in degrees north or south of the equator. Lines of The equator is at 0 latitude. The poles are at 0 latitude. Summarize the information about degrees of latitude by completing the table. Degrees of Symbol Actual Distance Degree km Minute. km Longitude Use with page. Complete each sentence to help you remember information about longitude. Lines of longitude are also known as meridians. Longitude is distance in degrees east or west of the prime meridian. The prime meridian is the reference point for meridians. It represents 0 longitude. The prime meridian goes through Greenwich, England. Points west of the prime meridian are numbered from 0 to 0 west longitude. Points east of the prime meridian are numbered from 0 to 0 east longitude. Mapping Our World

3 Name Section. and Longitude (continued) Use with pages. Compare and contrast information about latitude and longitude. Place each statement in the Venn diagram to show whether it is true for latitude, longitude, or both. Two statements have already been written in for you. Lines are parallel. Lines converge at a point. Lines form circles. Lines form semicircles. Degrees cover consistent distances. Degrees do not cover consistent distances. Necessary to precisely locate positions on Earth Longitude Both Lines converge Necessary to at a point. precisely locate Degrees do not positions on cover consistent Earth distances. Lines form semicircles. Lines form circles. Lines are parallel. Degrees cover consistent distances. Time Zones Use with page. Analyze the figure below showing U.S. time zones. Assume that it is :00 in the Mountain time zone. Draw the hands on the other clocks to show the time it would be in each of the other U.S. time zones. Alaska Standard Time 0 0 Pacific Mountain Central Eastern Hawaii-Aleutian Standard Time 0 AK HI WA OR ID NV UT CA AZ MT WY CO NM VT NH ME ND MN WI NY MA SD RI MI IA IL IN OH PA NJ CT NE DE WV VA MO MD KS KY NC TN OK AR SC GA MS AL TX LA FL SYNTHESIZE Write the instructions you would give a classmate to locate the point N, E on a globe. Responses should demonstrate an understanding of using latitude and longitude to locate points. Section. and Longitude

4 Mapping Our World Section. Types of Maps Skim Section of your text. List the three map projections mentioned in the headings and illustration captions.. Mercator projection. conic projection. gnomonic projection New In the left column, write the terms defined below. gnomonic projection a map made by projecting points and lines onto a piece of paper that touches a globe at a single point Mercator projection a map that has parallel lines of latitude and longitude topographic map a map that shows changes in elevation of Earth s surface conic projection a map made by projecting points and lines from a globe onto a cone map scale the ratio between distances on a map and actual distances on the surface of Earth contour interval the difference in elevation between two side-by-side contour lines on a map map legend a table that explains what the symbols on a map represent contour line Academic distort a line on a map that connects points of equal elevation Define the following term. to twist out of the true meaning or proportion Mapping Our World

5 Section. Types of Maps (continued) Mercator Use with page. Complete the table to organize information about Mercator projections. Made by Advantages Disadvantages Uses Mercator parallel lines of latitude and longitude show the correct shape of landmasses; indicate directon in straight lines distort areas of landmasses navigation of ships and planes Conic Use with page. Organize information about conic projections by filling in the graphic organizer. Made by: projecting points and lines from a globe onto a cone Advantages: highly accurate for limited areas Conic Disadvantages: distortion near top and bottom of projection Uses: road maps, weather maps Gnomonic Use with page. Complete the following sentences to help you understand gnomonic projections. Gnomonic projections are made by projecting points and lines from a globe onto a piece of paper that touches the globe at a single point. The advantage of these projections is that they plot the shortest distance between two points. The disadvantage of gnomonic projections is that they distort direction and distance between landmasses. They are used by air and sea navigators to plot great-circle routes. Section. Types of Maps
