2. 2 Vocabulary This word is abstract. If something is abstract then it is not concrete or real. If you cross the Alaska state line you do not actually see a line on the ground. The Alaska state line is _____________.

3. 3 Vocabulary Abstract geographical features like state boarders, the Equator, and lines of latitude and longitude are visible on maps and globes, but are not visible on Earth. If something is ____________ then it is not concrete or real.

4. 4 Vocabulary This word is latitude. Lines of latitude are abstract, or imaginary lines that can help you find a location on a map or globe.

5. 5 Vocabulary Latitude lines are equally spaced apart. The lines of latitude look like the rungs (the part you step on) on a ladder.

6. 6 Vocabulary Latitude lines run parallel to the Equator. A line of __________ can help me find a location on a map or globe.
