| Question | Answer |
|---|---|
| when placing coordinates in order east to west , you must look at longitude coordinates (T/F) | True |
| the equator represents 0 degrees longitude (T/F) | False |
| if it is 3:30 pm in Central standard time, then it is 1:30 in Pacific standard time (T/F) | True |
| it is earlier in the west than i the east because the earth rotates in a clockwise direction (T/F) | False |
| there are 4 time zones in the united states (T/F) | False |
| by using 4 satellites rather than 3, GPS would provide a much more accurate location (T/F) | True |
| the global positioning system, or GPS, is a satellite-based, radio navigation system that allows users to determine their exact position on earth (T/F) | True |
| remote sensing is a way of collecting information about earth from a distance (T/F) | True |
| lines of latitude are parallel (T/F) | True |
| The topex/poseidon satellite allows its users to determine their exact position on earth (T/F) | False |

| if you travel one time zone to the west in the U.S., you must set your watch _________ | back one hour |
| each time zone is separated from the next by ___________ of time on a clock | 1 hour |
| what would be necessary items that would need to be put into a key for a geologic map? | Rock layers, have a scale |
