Location
On a globe, are lines of latitude horizontal or vertical?
Horizontal
"Lat is flat"
What type of map has a scale of 1:50 000 and shows both natural and cultural features and relief through contours?
A Topographic Map
What do widely spaced contour lines indicate about the slope?
A gentle or gradual slope.
What are isobars?
Lines on a weather map joining places of equal atmospheric pressure.
Do contour lines cross each other?
No. Contour lines do not cross because each line represents a different elevation.
When writing a grid reference, which digits must you write first?
A) The x-axis digits (easting)
B) The y-axis digits (northing)
C) It does not matter which digits you write first
A) You must walk to the ladder (X axis) before you climb it (Y axis)
What does a scale show?
How much smaller the map has been drawn compared to the real world.
What do contour lines on a map show?
They show the height (elevation) of the land above sea level.
What does it mean when isobars are close together on a weather map?
They indicate strong winds.
When writing a coordinate, which comes first: latitude or longitude?
Latitude comes first, followed by longitude.
How many lines of longitude are there?
360
What is the key issue with the Mercator Projection Map?
It greatly distorts the size of countries and land areas, especially near the poles.
E.g. It makes Greenland appear a similar size to Africa even though Africa is about 14 times larger.
What are index contour lines?
Index contour lines are the thicker, darker contour lines that show the elevation of the land at that line.
In which direction do winds blow around a low-pressure system?
Clockwise.
What is the name of the line of latitude at 23.5°S?
The Tropic of Capricorn
In a six-figure grid reference, what do the 3rd and 6th digits tell you? E.g. 665 311
The exact location within the grid square
What is the difference between large scale maps and small scale maps?
Large scale maps cover small areas likes a single neighbourhood or a city.
Small scale maps cover large areas like entire countries, continents, or the world.
What do closely spaced contour lines indicate about the terrain?
A steep slope.
What are lines on a map that join points of equal value called?
Isolines
How many minutes is each degree divided into?
60 minutes
What is the difference between an Area Reference (AR) and a Grid Reference (GR)?
An Area Reference uses 4 figures to locate the position of an entire grid square on a map. A Grid Reference uses 6 figures to pinpoint an exact location within that square.
What are the 5 conventions to use when drawing a map?
Scale, Orientation (North arrow), Frame, Title, and Key.
What do contour lines that form closed circles usually indicate?
A hill or high point.
What type of weather is usually associated with high-pressure systems?
Fine weather.
Which direction is North? Point to it.
