Unit 2 test Flashcards
models
a smaller copy to represent something
physical model
information that is provided so you can see it
mathematic model
mathematical relationships Express by symbols formulas and equations
graphical model
a graph provides a picture of a relationship of symbols formulas and equations
Earth shape
one could argue Earth shape is obliquely spiracle
Central Force
outward Force caused by spinning on Earth access
E=MC*2
energy equals mass times speed of elevation
evidence of Earth shape
1.photography
2. The Horizon of earth’s surface is curved
3.eclipses people would see the Earth’s shadow in the Moon
4.measurement of gravity gravity is a stronger the closer you get to the center of the Earth
5.Northstar of Polaris Polaris does not move
latitude
angular distance north or south of the Equator
equator
0 degrees starting point for measuring latitude
parallel lines
these lines are used for measuring latitude runs east to west
North/ South pole
90 degrees latitude is the maximum latitude one can travel
longitude
angular distance measured east to west of the Prime Meridian
Meridians
runs north to south from pole to pole
prime meridian
0 degrees starting point for measuring longitude
International Date Line
180 degrees maximum longitude
WEEL
W E
West Early (if you cross the International Date Line West it’s the next day)
E L
East Later (if you cross the International Date Line East it’s the day before)
time zones
the Earth has 24 time zones
width of time zones
15 degrees
u.s.a. Time zone
has four time zones
eastern time zone
Central Time Zone
Mountain Time Zone
Pacific time zone
Contour ( ISOlines)
lines connecting two points of equal value
contour lines
ISOlines that have elevation
elevation
the action or fact of elevating or elevated
isothermic
ISOlines on a map that are based on weather
approximate measurements of isolines
for example if the contour interval is 20 and the point is in between 20 and 40 it has to be in between(21-39) those numbers because it is not on a line
topographic map
most often models of areas of the Earth showing elevation
benchmarker
points on a topographic map that have the specific elevation.
Contour index lines
most often dark lines with numbers with elevation
contour interval
the difference between the contour lines
what contour lines look like on a hill
1.the closer spaced contour lines indicate = a steep slope
2. The Wider the space between the contour lines indicate = gentle slope
3.the evenly spaced contour lines indicate = uniform slope
laws of V
contour lines with River attached to them always bend up strain. the contour lines usually follow the river pointing in V to determine the direction of the river you flip the V upside down to get the direction
depression lines
contour lines that near depressions without Outlets are shown by closed hachured Contours, where the first hachured Contour is equal to the elevation of the line before.
the top of a topographic map
North
verbal scale
equates 2 different units
profile
side view of a landscape
gradient ( slope)
rate of change for field value between two locations
essentially slope with rise over run but has units
gradient formula
change in field value( rise) over distance( run)
gradient units
the USA uses miles over feet well everywhere else uses m / km
magnetic deviation
the comparison from true north
connecting lines on a contour map
when connecting lines on a contour map a few key things to do
1.go off the map
2.make sure each of your lines is in between a number that is bigger than the interval and smaller than the interval
3.all numbers inside your interval should have a value of itself
diagram models
