CONS 127-Final Exam Study Guide
Questions With 100% Verified
Solutions | Solved
What is latitude and Longitude CORRECT ANSWERS Latitude is the line moving in the
North-South direction, Longitude is the line that goes around the Earth horizontally
Where is the Prime Meridian CORRECT ANSWERS Greenwich, England at 0 degrees
longitude
What is a parallel CORRECT ANSWERS A parallel is a circle connecting all locations
with a given latitude
What are the three ways the earths shape can be mathematically defined CORRECT
ANSWERS Geoid, Ellipsoid, Sphere
Geoid CORRECT ANSWERS Shape of the surface of the calmed oceans (best
representation of earth)
Ellipsoid CORRECT ANSWERS Where our A axis is longer than our B axis. (semi
major and semi minor axis)
What is the main difference between an equivalent and conformal projection CORRECT
ANSWERS In a conformal map projection the angles are preserved, equivalent
projection preserve the size of a country/landmass
Considering the case of Africa and Greenland, describe how map projection might
influence the perspective of the map viewer CORRECT ANSWERS when a
country/continent is projected to look smaller than it actually is, people may think it is of
lesser importance
How was a meter first defined? CORRECT ANSWERS A meter was a part of a distance
between the north pole and the equator
How is a meter defined now? CORRECT ANSWERS A fraction of how many seconds
light takes to travel across a meter
What is the name of the unit which is equal to 1000nm CORRECT ANSWERS
nanometer
Which covers more area, a small or a large scale map? CORRECT ANSWERS A small
scale map
, What are two ways scale can be indicated on a map? CORRECT ANSWERS Graphic,
scale, verbal scale
What kind of map scale would be appropriate for representing large countries and or
continents? For a city neighbourhood? CORRECT ANSWERS A verbal scale would be
used for neighbourhoods (large scale), Maps of countries are in small scale
Name three devices which can measure distance at different scales CORRECT
ANSWERS GPS, theodolite, geodetic marker
What is the difference between relative and absolute position? CORRECT ANSWERS
Relative position is based off of where you are in relation to something, absolute
position is your absolute coordinate location
What is a geodetic marker? CORRECT ANSWERS Points of absolute coordinate to
mark key survey points on the earths surface
In ocean navigation, which is easier to calculate? latitude or longitude CORRECT
ANSWERS Latitude
What is the critical measurement to obtain an accurate longitude CORRECT
ANSWERS time on the ship/place you are and time/place of a starting point
What is an orbit? CORRECT ANSWERS A path taken by an object created by gravity, it
keeps going around but never falls all the way
What are some ways we can define space? CORRECT ANSWERS Space is an area
outside of earth with no atmosphere or oxygen
What type of orbit would be used to monitor weather CORRECT ANSWERS
Geostationary orbit
Which type of orbit is used for GPS tracking CORRECT ANSWERS far elliptical orbit
What orbit is best for getting to and returning from space easily? CORRECT ANSWERS
Low earth orbit
Which orbit type are most remote sensing satellites in? why? CORRECT ANSWERS
Close elliptical orbit because the satellites have a broader view of the earth and don't
have to worry about drag effecting their proximity to the earth
Name three types of satellites that use geostationary orbit CORRECT ANSWERS
television, cellphone, weather
In what decade were the first images collected from spacec? From what platform?
CORRECT ANSWERS The first images were collected on balloons in the 1940s
