|
parallels.
|
any circle that runs east and west around the Earth and that is parallel to the equator; a line of latitude
|
|
|
latitude.
|
the angular distance north or south from the equator; expressed in degrees
|
|
|
meridian.
|
any semicircle that runs north and south around Earth from the geographic North Pole to the geographic South Pole
|
|
|
longitude.
|
the angular distance east or west from the prime meridian; expressed in degrees
|
|
|
topography.
|
the size and shape of the land surface features of a region, including its relief
|
|
|
elevation.
|
the height of an object above sea level
|
|
|
contour lines.
|
a line that connects points of equal elevation on a map
|
|
|
contour intervals.
|
the difference in elevation
|
|
|
Describe the difference between the lines of latitude and longitude.
|
- Latitude; horizontal; north to south. Has range 0 - 90 degrees
Longitude; vertical; west to east. Has range 0 - 180 degrees |
|
|
Explain how latitude and longitude are used to find specific locations on Earth.
|
Each latitude and longitude degree pin points a certain spot on the planet.
|
|
|
Explain how a magnetic compass can be used to find directions on Earth.
|
Earth has magnetic properties as if a powerful bar shaped magnet were buried at Earth's center at an angle to Earth's axis of rotation.
|
|
|
How might GPS technology be beneficial when used in airplanes or on ships?
|
In the sky or on water, it is easy to get lost so if you have a GPS then it is easy to know where your location is.
|
|
|
Explain how elevation is shown on a topographic map.
|
Contour lines are used to show elevation.
|
|
|
Summarize how you can use information on a topographic map to compare the steepness of slopes on the map.
|
When the lines are close on a topographic map then it is steeper in elevation. When the lines are widely spaced apart then the ground is level.
|
|
|
What type of map would be the most useful to a scientist studying earthquake patterns: a geologic map or a topographic map?
|
Geologic map
