Mapping of Our World
What feature on a map shows the ratio of map distance
to actual distance on Earth?
Map Scale
What type of map shows changes in elevation on
Earth’s surface?
Topographic map
What technology is used to map sea floor features?
Sonar
and/or
Topex Poseidon satellite.
What is the disadvantage of the Mercator projection?
It distorts the size of the land masses near the poles
Example: Greenland is drawn way too big
What is the reference point for lines of latitude?
The Equator (0 degrees Lat)
What is the reference point for lines of longitude?
The Prim Meridian (0 degrees longitude)
What is the distance of one degree of latitude?
69 miles or 111 Km
What is the indication of a depression on a map?
Hatchured contour lines
What is the term for map making?
Cartography
What is the location of the international date line?
180 degrees Longitude (Pacific Ocean)
Which lines run north and south and measure east and
west?
Longitude
Which lines run east and west but measure north and
south?
Latitude
What is the location of the prime meridian?
0 degrees Longitude
(runs through Greenwich England)
What is the location of the equator?
0 degrees Latitude
What is a contour interval?
The difference in elevation the lines are counting by.
If you have 4 concentric circles (like tree rings) and
the out side circle is at sea level and there is a 20 m
contour interval what could be the height of a bench
mark on the inside of the inner most circle?
79 m (one less than the next contour line would be)
The apparent altitude of Polaris is equal to what?
The observers latitude
On average which are bigger, the parallels or
meridians?
The meridians (they all form great circles)
How many time zones are there in the US?
6 (including Alaska and Hawaii)
What type of line connects areas of equal elevation?
Contour lines
Which type of map shows you parallel lines of
longitude?
Mercator
Where do lines of longitude intersect?
At the poles
What are great circles?
Lines that bisect the Earth in half
(All connecting lines of Longitude and the equator)
Which map is useful for plotting long trips by air or
sea?
Gnomonic Projections
Which map is useful for navigating short trips by car
such as using a GPS?
Conic projections
What is an index contour?
A contour line with the value on it
What is a map legend?
A key that describes map symbols
What is the term for collecting data about Earth far
above Earth’s surface?
Remote sensing
How fast does light travel in a vacuum?
186,000 miles/s
What type of radiation is light apart of?
Electromagnetic
1 : 100,000 is which type of scale?
Fractional scale
A statement on a map that tells you about the scale is
which type of scale?
Verbal scale
What is the term for the number of waves that pass by
a particular point each second?
Frequency
Which type of scale shows you a line that measures
distance of the map compared to real life?
Graphic Scale
Which satellite creates images of the ocean floor?
Topex Poseidon
What does GPS stand for?
Global positioning system
Why would a ship appear to sink when heading off in
the distance?
The Earths surface is curved
What is the name of the Earth’s shape?
Oblate spheriod
At sea level which location would be closest to the
center of the Earth (more gravity and weight)?
The poles
Where on Earth would you weigh the least?
The Equator
What is the equatorial circumference of the Earth?
About 25,000 miles or 40,000 Km
(24,901miles or 40,075 Km)
What could you measure with a straw, protractor and
string?
The altitude of a star
How can you find Polaris using the big dipper?
The end two stars of the cup point to Polaris
(which is the end star of the little dippers handle)
As an observer travels northward, what happens to the
altitude of Polaris?
The altitude increases
What happens to your view of Polaris as you travel
South passed the equator?
You can no longer see it.
How can you tell the direction of flow of a river using
the contour lines shape?
The contour lines bend upstream
What is the formula for gradient?
Gradient = Change in field value
Distance
What is the formula for percent error?
(The absolute value of the numerator)
% Error = Accepted value – estimate
Accepted value
X 100

rocks mass to be 4 grams when the actual value is 5
grams?
20%
