1. Earth Systems - Chapter 1.3 Mapping Our World

2. Learning Objectives Identify the seven continents on a map Identify the four oceans on a map Distinguish between the longitude and latitude lines on a globe Differentiate between the equator and the prime meridian Explain how the tilt of the Earth determines the season Define key words: continent, degrees, equator, globe, hemisphere, latitude, longitude, meridians, ocean, parallel, polar regions, poles, prime meridian

3. Monday’s Assignment: 1.Read Chapter 1.3 – Mapping Our World (pages 11 to 17) 2.Using good note taking strategies (e.g. Cornell Notes), take effective notes. As a reminder, I have posted a chapter outline on Canvas that some of you may find very useful. 3.Answer teacher asked questions related to the chapter 4.Be prepared to participate in meaningful discourse tomorrow during class.

4. Latitude Vocabulary Lines running horizontally; they measure distance north and south Longitude Lines running vertically; they measure distance east and west from the Prime Meridian

5. Prime Meridian Vocabulary Marks 0-degrees on the longitude line International Date Line Marks 180-degrees on the longitude line (the opposite side of the prime meridian); travelling east subtract one day; going west adds a day

6. Equator Vocabulary The line of latitude around the middle of the Earth that marks o-degrees Eastern & Western Hemispheres The two hemispheres formed by the prime meridian and the 180- degree meridian

7. Northern & Southern Hemispheres Vocabulary The two hemispheres formed by the equator Globe A spherical model of Earth

8. Mercator projection Maps and Mapping Rectangular; longitude lines are parallel; direction shown accurately; Although first created in 1569, this map is still used by sailors toady Sizes and distances distorted

9. Robinson projection Maps and Mapping Most distances, sizes, and shapes are shown accurately Distortions around the map edges

10. Conic projection Maps and Mapping Made by wrapping a cone of paper around a globe at a particular line of latitude; great accuracy over small areas; good for roads and weather maps Lots of distortion on most of the map

11. Gnomonic projection Maps and Mapping Made by placing a piece of paper on a globe so it touches a single point on the globe’s surface; shows the shortest distance between two points; used by sailors and navigators Exact distance and directions are distorted

12. Topographic Maps Maps and Mapping A map that shows relief features of the Earth's surface by means of contour lines that show changes in elevation; often used by hikers and the military

13. Remote sensing Advance Technology The scanning of the Earth by satellite or high- flying aircraft in order to obtain information about it.

14. Example of Remote Sensing Google Maps: https://www.google.com/maps/place/Shaw+High+School/@32.558213,- 84.909585,636m/data=!3m2!1e3!4b1!4m2!3m1!1s0x88f334eff00e2ac 5:0xbc17460df0f4757d https://www.google.com/maps/place/Shaw+High+School/@32.558213,- 84.909585,636m/data=!3m2!1e3!4b1!4m2!3m1!1s0x88f334eff00e2ac 5:0xbc17460df0f4757d Google Earth:

15. Tips to Remember Latitude is always given before longitude (49° N 100° E) Latitudes are parallel, but longitudes are not Degrees West and South are sometimes referred to as negative degrees (-12° -23° is the same as 12 S 23 W) A place's latitude effects its climate, but its longitude does not Key longitude lines are the Prime Meridian (0°) and the International Date Line (180°)
