Atlas maps - physical and human features
atlasA book containing global and national maps. provide maps on global and national scaleThe ratio of a distance on a map, graph or diagram to the corresponding actual distance.. Some atlas maps show physical featureA natural landform., whilst others show human featureAn aspect to do with humans, eg poor sanitation..
Physical maps
Physical maps show natural features such as mountains, lowlands, major rivers, seas, oceans and ecosystemA community of animals, plants and microorganisms, together with the habitat where they live. like deserts and rainforests on a global scale. On a national scale, physical maps show reliefThe way that the landscape changes in height. and drainage features, such as rivers.
Some maps show physical features that are experienced rather than seen. Examples of this are average temperature and rainfall maps.
How to read human and political maps
Political maps show country boundaries and major cities. Human thematic maps show features that people have created. Examples of these are population distributionThe location of people in an area., migrationWhen people move from one place to another. flows, transport routeA form of transportation, eg a road, railway or ferry route. and settlementA place where people live. layout.

Examples of this are life expectancyThe average number of years a person is expected to live depending on where they live., standard of livingThe amount of wealth or personal comfort that a person or group of people have. or even measures of world happiness.
Direction
Often, maps should have a directionInformation to give the direction of travel, or the direction of a force, for example, a speed of 20 m s-1 to the left, or a force of 15 N to the right. arrow to show which way is north. North is at the top of the globe and south is at the bottom. East is to the right and west is to the left. Compass points in between these four are shown as combinations, eg the point in between north and east is called north-east. If the point is slightly closer to the east, it is called east-north-east.
What are latitude and longitude?
latitudeImaginary lines around the Earth running parallel to the equator. These are measured in degrees north or south of the equator. and longitudeImaginary lines around the Earth running from the north to the south pole. These are measured in degrees east or west of the Greenwich or Prime Meridian. enable users to find locations on atlases.
- As the Earth is a sphere, lines of latitude and longitude are measured using degrees of a circle.
- Lines of latitude run from east to west. The EquatorThe line around the centre of the Earth, parallel to the Tropics of Cancer and Capricorn. is a line of latitude that lies at 0掳. Lines above this are shown as 掳N (north) and lines below this are shown as 掳S (south).
- Lines of longitude run from north to south. The Prime MeridianThe line of longitude at 0掳 that runs through Greenwich, in London. or Greenwich MeridianThe line of longitude at 0掳 that runs through Greenwich, in London. in London is a line of longitude at 0掳. Lines to the right of this are shown as 掳E (east) and lines to the left of this are shown as 掳W (west).
Latitude is shown first and longitude is shown second, eg Manchester in the UK is at 53.5掳N, 2.2掳W.
