TOPIC 1 OBJECTIVES
DIMENSIONS OF THE EARTH
1. Define altitude as used in locating stars, sun, moon, etc.
2. Using the Big Dipper, determine the location of the North Star.
3. Determine and write the latitude on Earth, given the altitude of Polaris.
4. Given cross sectional diagrams of the Earth, identify the one that represents the actual appearance of the Earth's shape.
5. Using the Earth's polar and equatorial diameters, describe how this represents the Earth as being slightly oblate.
6. List three kinds of evidence that can be used to determine the shape of the Earth.
1)
2)
3)
7. Given the Earth Science Reference Tables (ESRT) identify any listed physical value or dimension of the Earth.
8. Calculate the number of miles or kilometers in a degree of latitude.
9. Determine the circumference of the Earth, using the difference in altitude of a star from two different positions, taken at the same time, on a North-South line.
10. Describe the parts of the Earth:
a. Lithosphere:
b. Atmosphere:
c. Hydrosphere:
11. Compare the relative densities of the lithosphere, atmosphere, and hydrosphere.
12. a. Given graphs of distance vs. ocean depth identify the graph which best shows the ocean floor relief in true scale.
b. Given diagrams showing the Earth and its atmosphere, identify the diagram most nearly in true scale.
13. Create a model, which best shows, the relief of the Earth's surface in true scale.
14. On a map or globe, identify lines of latitude and lines of longitude.
15. Given latitude and longitude values (degrees, minutes, seconds), identify that location on a map.
16. Define isoline.
17. Construct an isoline map, given measured values.
18. Given a topographic map, be able to interpret and read the map.
19. Given a field map with isolines, match the correct profile with the change in isoline values.
20. Calculate the gradient on a topographic map, given the difference in elevation between two places.
