CONS 127 FINAL COMPREHENSIVE STUDY
GUIDE WITH SOLUTIONS
◉ What are two ways scale can be indicated on a map?
Answer: - graphic scale/bar scale
- fractional scale/ratio scale
◉ What kind of map scale would be appropriate for representing
large countries and/or continents? For city neighbourhood?
Answer: 1. small scale (cover a large area with coarse detail)
2. large scale (cover a small area with great detail and accuracy)
◉ Name some 3 devices which can measure distance at different
scale
Answer: - electron microscope
- optical microscope
- camera
- telescope
◉ What is the difference between relative and absolute positioning?
Answer: - your position in relation to something else (dead-
reckoning)
,vs.
- coordinates of a point in space - identified by using a coordinate
system, such as longitude/latitude (position fixing - a fixed location
that never changes)
◉ What is a geodetic marker?
Answer: - points that are the basis for the mapping of the Earth's
surface
- a marker placed in the ground that gives us accurate information
on their relative and absolute position and is used to calculate other
points by using triangulation
- every marker has a unique latitude and longitude
◉ In ocean navigation, which is easier to calculate, latitude or
longitude?
Answer: Latitude because you can use the stars to measure your
position
◉ What is the critical measurement to obtain an accurate longitude?
Answer: - obtaining the precise local time
- time relates to longitude because of the earth's rotation
◉ What is an orbit?
Answer: - a curved path around a celestial object
, - the path is created from gravitational attraction between the two
objects
- in reality, it is the effect of continuously falling towards the target
◉ What are the ways that we can define space?
Answer: - a gradual concept that we move up through
- there is no 100% distinguishing line, the atmosphere gradually
changes as we go further up (the density of air decreases and air
pressure lowers)
- space would truly be defined as an area that has no atmosphere/air
particles but in reality we think of things being in space that are
closer
- roughly 380 km away is where we start to say space starts
◉ types of orbits
Answer: - low-earth orbits
- close elliptical orbits
- far elliptical orbits
- geostationary orbits
◉ Which type of orbit would be used to monitor weather?
Answer: geostationary orbit
