geographical skills Flashcards
1
Q
Latitude
A
- measuring the distance north or south of the equator
- run parallel to the equator
- tropic of cancer, tropic of capricorn, arctic circle, antarctic circle.
- 0 is the equator
2
Q
longitude
A
- measures the distance east or west of the prime meridian(0)
- lines of longitude- meridians that converge at the poles
- international date line- 180 longitude.
3
Q
Area reference
A
- general location using 4 digits.
- identify the easting( first 2 digits), and northing (last 2) within the grid square
- from the bottom left corner
4
Q
Grid reference
A
- using a 6 digit identifier
- first 3 digits is the eastings then how far along the grid(1-10) the point is.
- last 3 digits are the northings then how far up the grid the point is
5
Q
scale
A
- distance in real life corresponding to the map
- e.g. 1:25,000 - 1cm on map = 250m on ground(large scale)
- e.g. 1:100,000- 1cm on map = 1km on ground. (small scale)
6
Q
distance
A
- measure point to point on the map then convert using the scale.
7
Q
contour intervals
A
- difference in elevation between contour lines on a map
- close contours = steep terrain(higher elevation)
- wide contours = indicate gentler slopers(lower elevation)
- contour interval = the number between each contour value.
8
Q
synoptic charts
A
- a summary of weather conditions happening over a specific location at a certain point of time.
9
Q
Isobars(synoptic charts)
A
- connects places of equal air pressure
- every point on isobar = same pressure
- closer = stronger, further = gentle winds
- high pressure system = broad, high number (pressure)in the middle
- low pressure system.= steep, low number(pressure) in the middle
10
Q
high and low pressure systems (synoptic charts)
A
- high pressure systems = sinking air = stable weather, inc. temp, dec. wind speed, dec pre., sunny
- low pressure system = rain, poor weather, unstable weather, decrease in temp, inc wind speed
11
Q
cold fronts
A
- front of a moving mass of cold air
- moves in direction of pointing arrows
- similar weather to low pressure systems
- change in wind direction
- dramatic fall of temp.
12
Q
wind directions
A
- shows wind strength and where the wind comes from
- where the wind is coming from(look for were the arrow is pointing)
e.g.westerly winds blow east.
