11. Compare the elevation of a coastal plain to that of an interior plain.

A coastal plain has low elevation, but an interior plain can have high or low elevation.

13. What do geologists call an area where there is mostly one kind of topography?

A large area of land where the topography is similar is called a landform region.

14. The South Island of New Zealand lies at about 170 E. What hemisphere is it in?

It is in the Eastern Hemisphere because it lies 170 degrees east of the prime meridian.

15. What is one advantage of a Mercator projection? What is one disadvantage?

Checking Concepts

15. What is one advantage of a Mercator projection? What is one disadvantage?

On a Mercator projection, the size and shape of landmasses near the equator are distorted only a little; but as you move towards the poles, size and shape become more distorted.

16. What information does a map's contour interval provide?

Checking Concepts

16. What information does a map's contour interval provide?

A map's contour interval states the amount by which elevation changes between each contour line.

17. How do the contour lines on a topographic map indicate the slope of the land?

Checking Concepts

17. How do the contour lines on a topographic map indicate the slope of the land?

Contour lines that are far apart indicate flat or gently sloping land. Contour lines that are close together indicate steeply sloping land.

Thinking Critically

Which would be more likely to show a shallow, 1.5 meter deep depression in the ground- a 1 meter contour interval or a 5 meter contour interval?

Thinking Critically

Which would be more likely to show a shallow, 1.5 meter deep depression in the ground- a 1 meter contour interval or a 5 meter contour interval?

A 1.5 meter-deep depression would not show on a map with a 5 meter contour interval because that interval only shows changes in elevation greater than 5 meters. The depression would show on a map with a 1-meter contour interval because the depression is greater than 1 meter.

21. How would the colors in a satellite image of an area compare with those in a color photograph of the same area?

Thinking Critically

21. How would the colors in a satellite image of an area compare with those in a color photograph of the same area?

The colors in the photograph and the satellite image would be different. For example, vegetation often appears red, water appears black, and cities appear grayish blue.
