Parts of a map

Title (what it shows) · key / legend (what the symbols mean) · compass rose (which way is north) · scale (1 inch = 50 miles) · grid (letters and numbers, or latitude and longitude). A map is a picture of a place from above, a bird’s-eye view; a globe is a small round earth.

Directions

  • Cardinal: North, East, South, West, clockwise (“Never Eat Soggy Waffles”). Intermediate: NE, SE, SW, NW.
  • The sun rises in the east and sets in the west; at noon it is south (in the northern hemisphere). A magnet points north.
  • Bearings: N = 0°, E = 90°, S = 180°, W = 270°. Orienteering: set the map to north, take a bearing, pace the distance.

International Date Line180°a new day begins
North / South Pole90°N / 90°Sthe ends of the axis
Latitude lines lie flat like ladder rungs (parallels); longitude lines run pole to pole (meridians). Say latitude first: 40°N, 74°W. Time zones: 24 zones of 15°, one hour apart, set in 1883 for the railroads.

Topographic maps (grades 6, 8)

  • Contour lines join points of equal height; the contour interval is the step between them. Close lines = steep; far apart = gentle; a V points upstream where lines cross a river.
  • Draw a profile by plotting heights along a line.
  • A flat map must stretch somewhere: Mercator stretches the poles (Greenland looks as big as Africa).

GPS and GIS

GPS: satellites broadcast the time; a phone measures how long each signal took from four or more satellites and fixes its place. GIS stacks map layers (roads, rivers, elevation, people) by coordinates; QGIS is free. Old maps and new maps compared show how a city grew.

2Landforms, Water & ClimateK–6 · the shape of the land

Landforms
WordMeaning
mountain / hillhigh land; a range is a chain; a pass is a low way through
plateauhigh flat land
plain / prairielow flat land; grassland
valleylow land between hills; a canyon is a deep, steep valley
islandland with water all around
peninsulaland with water on three sides (Florida, Italy)
isthmusnarrow land joining two larger (Panama)
capea point of land into the sea
desertunder 10 inches of rain a year; hot or cold
coast / beachwhere land meets sea
deltafan of mud where a river meets the sea (Nile, Mississippi)
glaciera slow river of ice
Water words
WordMeaning
source → mouthwhere a river starts → where it ends
tributarya river that joins a bigger one; a confluence is the joining
floodplainflat land a river floods
lake / pondwater with land all around; fresh
sea / oceansalt water; a gulf or bay is sea reaching into land
straitnarrow water joining two seas (Gibraltar)
harborsheltered water for ships
spring / well / aquiferwater that comes up / is dug for / is stored in rock

The water cycle

Evaporation → condensation (clouds) → precipitation (rain, snow) → rivers run to the sea → springs and wells. Rivers at work: weathering breaks rock, erosion carries it, deposition builds deltas and floodplains.

Climate

  • Weather is today; climate is the pattern over years.
  • Latitude: near the equator the sun strikes straight down (hot); near the poles it slants (cold). Four seasons in between.
  • Altitude: higher is colder (snow on Kilimanjaro at the equator).
  • Rain shadow: wet on the windward side of mountains, dry behind.
  • Oceans: the Gulf Stream warms Europe; gyres circle the oceans; the moon makes two tides a day.
  • Köppen zones: tropical, dry, temperate, continental, polar.

Land and water

  • Rivers: the Mississippi (with the Missouri and Ohio) drains the middle; the Colorado cut the Grand Canyon; the Rio Grande is the Mexican border; the Columbia runs to the Pacific.
  • Mountains: the old, rounded Appalachians in the east; the young, high Rockies in the west. Deserts: Mojave, Sonoran, Great Basin.
  • Great Lakes: Huron, Ontario, Michigan, Erie, Superior (HOMES). Ties: Lewis and Clark (1804–06), the Oregon Trail, the Pony Express (1860), the telegraph (1844), the railroad (1869).

5Explorers, Ports & Why Cities Stand Where They Dogrades 3–5, 8

Explorers
WhoWhenWhat
Leif Eriksonc. 1000Vikings reach Vinland (North America)
Marco Polo1271–95Venice to the court of Kublai Khan by the Silk Road
Ibn Battuta1325–54the great traveler of Africa and Asia
Columbus1492crosses the Atlantic to the New World
Magellan / Elcano1519–22first voyage around the world
Captain Cook1768–79maps New Zealand, Australia, the Pacific; cured scurvy with diet
Lewis and Clark1804–06across the Louisiana Purchase to the Pacific
Peary and Henson1909near the North Pole
Amundsen1911South Pole (Shackleton’s Endurance, 1914–16)
Hillary and Tenzing1953Everest
Missionaries as geographers: William Carey (India), David Livingstone (crossed Africa), Hudson Taylor (inland China), Mary Slessor (Calabar). Judge explorers honestly: courage and skill, real wrongs, exchange across the ocean.

Site and situation

  • Cities grow where a river could be crossed (ford, then bridge: Oxford, Frankfurt), where rivers meet (confluence: Pittsburgh), at the fall line where boats stop and mills start (Richmond), and on a defensible hill beside a harbor (Athens).
  • River civilizations: the Nile (Egypt), Tigris and Euphrates (Ur, Babylon), Indus (Mohenjo-daro), Yellow River (Yu the Great).
Ports, straits and canals
KindNames
Great portsVenice, Amsterdam, London (Thames), New York (Erie Canal, 1825), Rotterdam (Rhine), Singapore, Hong Kong
Choke-point straitsGibraltar, the Bosporus, Malacca, Hormuz, the English Channel
CanalsGrand Canal of China, Suez (1869), Panama (1914), St. Lawrence Seaway (1959)
Malcom McLean’s container (1956) made a ship load in hours instead of days; the Silk Road, the compass and sails that beat against the wind made trade possible.

Water first

Almost every great city began at water: a crossing, a confluence, a fall line or a harbor. Ask of your own town: where is the river, and why here?
