Question

1. why would a landsat photo be better than an airplane photo for mapping a small forest tree?

a. airplane photos are not as good quality.
b. the satellite is further away from the earth.
c. landsat uses visible and infrared radiation.
d. landsat uses visible and ultraviolet radiation.

1. what is a graphic scale?

a. a statement that expresses distance, such as \one centimeter equals one kilometer\
b. a ratio that expresses distance, such as 1:50 000
c. a line like this: 0 1 2 3 4 miles

d. a diagram that shows the elevation of the hills and valleys of an area

1. how can you identify an index contour?

a. index contours never have numbers
b. index contours are bold with numbers
c. index contours are different colors
d. index contours are longer

1. on a topographic map, the difference in elevation between two side - by - side contour lines is called the

a. contour interval
b. scale
c. depression contour
d. index contour

Explanation:

1. Landsat uses visible and infrared radiation which can provide more detailed information for mapping a small forest tree compared to airplane photos. Airplane photos may have limitations in resolution and spectral information.
2. A graphic scale is a line - like representation (e.g., 0 1 2 3 4 miles) that shows distance on a map.
3. Index contours are bold and have numbers on a topographic map to indicate elevation.
4. The difference in elevation between two side - by - side contour lines on a topographic map is called the contour interval.

Answer:

1. c
2. c
3. b
4. a
