27
make sure you can recognize longitude and latitude maps, and topographic maps
okiii
28
name two uses for a topographic map
1. hiking 2. planning 3. engineering
29
what is remote sensing
method of obtaining information about the properties of an object without coming into physical contact
30
what kind of waves does sonar use
sound waves
31
which sonar based remote sensing system was used to map the ocean floor
sea beam
32
explain the difference between passive remote sensing and active remote sensing
passive: satellite detects energy radiating from energy active: satellite sends signal and receives reflected signals
33
does sea beam use active or remote sensing
active

3
35
name four pieces of info that can be measured with gps
1. location 2. elevation 3. direction of movement 4. speed
