Tell them apart

1.3.1 — the 8 pairs that get mixed up

Most mix-ups happen when two words sit next to each other. These are the 8 pairs worth practicing apart. The 4 marked most confused are the ones the course itself flags, or that sit closest together.

Cover the right-hand column with your hand, read the left definition, and say which term it is out loud before you look. Then swap sides.

most confused
latitude

North–south distance from the equator. Lines run east–west. They get shorter toward the poles.

vs
longitude

East–west distance from the prime meridian. Lines run pole to pole and are all the same length.

How to tell Latitude lines go side to side (the lesson's football trick: a lateral pass goes to the side). Longitude lines are always long, pole to pole. GPS gives both. You still read latitude first.
most confused
equator

0° latitude. Naturally in the middle of the poles.

vs
prime meridian

0° longitude. Chosen in 1884. Runs through Greenwich.

How to tell The equator is the zero for north and south. The prime meridian is the zero for east and west. Only the east-west zero had to be chosen at a meeting.
most confused
planar projection

Globe onto a flat wall. One hemisphere. Polar maps.

vs
cylindrical projection

Globe onto a tube, then unrolled. Whole world. Stretches the poles.

How to tell Ask: one end of the Earth, or the whole wrap-around? Polar view → planar. Usual rectangular world map → cylindrical.
physical map

Landforms and water: mountains, rivers, deserts.

vs
political map

Human borders and cities: countries, states, capitals.

How to tell Mountains and rivers vs countries and capitals.
most confused
thematic map

One theme, still on a normal land-area outline.

vs
cartogram

Places resized by a statistic, not by land area.

How to tell If the countries still look like themselves, it is thematic. If they balloon or shrink, it is a cartogram.
hierarchy

Important things get more space and a more prominent position.

vs
balance

Spread elements so the frame is not crowded in one place and empty in another.

How to tell Importance vs evenness. Both are design rules on your study sheet.
Tropic of Cancer

~23.5° N. Overhead sun on the June solstice.

vs
Tropic of Capricorn

~23.5° S. Overhead sun on the December solstice.

How to tell Cancer is north. Capricorn is south. Same job, opposite hemisphere.
Arctic Circle

~66.5° N. Polar day in June, polar night in December.

vs
Antarctic Circle

~66.5° S. Polar day in December, polar night in June.

How to tell Arctic = north. Antarctic = south. The 24-hour sun and dark swap on opposite calendars.
If you only remember one thing Demography is the study; demographics are the data. Population is how many; density is how packed. Deviance is society rejecting you; a counterculture is a group rejecting society. Culture shock is the feeling; acculturation is the adjusting.
