Circle the best answer.
At 60° N, a Mercator map draws land 2 times too wide and 2 times too tall. How many times too big does Pia see its area?
- 1 time: the area is true
- 4 times too big
- 2 times too big
- 8 times too big
At about 75° N, Tala's Mercator map draws land about 4 times too wide and 4 times too tall. About how many times too big does its area look?
Square of land on a globe beside the same land on a Mercator map at about 75° N, drawn 4 times as wide and 4 times as tall. Square of land on a globe beside the same land on a Mercator map at about 75° N, drawn 4 times as wide and 4 times as tall. globe about 75° N Mercator map 4 times as wide 4 times as tall - About 4 times too big
- About 64 times too big
- About 8 times too big
- About 16 times too big
Data: Wikidata and Wikipedia, read Nov 11, 2026, rounded. Beside it, a Mercator map where Alaska looks larger than Mexico. Zee's friend says Alaska is bigger than Mexico, because Alaska looks much bigger on a Mercator map. Which response is right?
- Agree: a flat map shows sizes correctly
- Disagree: the map stretches Mexico, near the equator
- Disagree: Mexico is bigger; the map stretches far-north Alaska
- Agree: lands farther north are bigger
Ari's friend says a Mercator map is useless. Which response is right?
A Mercator map with a straight compass course drawn across the Atlantic Ocean. A Mercator map with a straight compass course drawn across the Atlantic Ocean. Mercator map straight compass course - Agree: it shrinks the lands near the poles
- Agree: it is the one flat map that bends anything
- Disagree: it keeps compass directions straight for sailors
- Disagree: it shows sizes correctly
Bo's friend says an equal-area map is the best map for every job. Which response is right?
An equal-area world map; land near the poles looks short and wide. An equal-area world map; land near the poles looks short and wide. equal-area world map - Agree: Mercator is the kind of map that bends land
- Agree: it keeps sizes and shapes true
- Disagree: it keeps sizes true but bends shapes
- Disagree: it makes the poles look too big
World map with straight, parallel longitude lines; latitude lines at 0°, 30°, 60° spaced wider and wider toward the poles. On Esme's Map P, latitude lines spread farther apart toward the poles, and longitude lines never meet. Which map is it, and what does it get wrong?
- Mercator: land near the equator looks too big
- Mercator: land near the poles looks too big
- Equal-area: land near the poles looks too big
- Equal-area: land keeps its true shape
On Jun's Map Q, latitude lines crowd closer together toward the poles, and land near the poles looks short and wide. Which map is it, and what does it keep?
World map with straight, parallel longitude lines; latitude lines at 0°, 30°, 60° spaced closer and closer toward the poles. World map with straight, parallel longitude lines; latitude lines at 0°, 30°, 60° spaced closer and closer toward the poles. longitude lines 60° 30° 0° 60° 30° - Equal-area: shapes true, sizes squashed
- Equal-area: sizes true, shapes squashed
- Mercator: sizes true, shapes squashed
- Mercator: nothing is stretched or squashed
Kira's Map R keeps every small shape right, and steady compass courses are straight lines on it. Which map is it, and what does it get wrong?
World map with a straight compass course drawn across an ocean; small islands keep their true outlines. World map with a straight compass course drawn across an ocean; small islands keep their true outlines. World map straight compass course - Mercator: sizes are wrong near the equator
- Globe: it keeps sizes and shapes true
- Equal-area: sizes are wrong near the poles
- Mercator: sizes are wrong near the poles
Luz's note says: "Mercator maps stretch land most near the equator." Which fix makes the note right?
A Mercator map with latitude lines 0°, 30°, 60° whose gaps grow toward the poles. A Mercator map with latitude lines 0°, 30°, 60° whose gaps grow toward the poles. Mercator map 0° 30° 60° latitude lines whose gaps grow toward the poles - Change "stretch" to "keep the true size of"
- Change "most" to "evenly"
- Change "equator" to "poles"
- Change "land" to "oceans"
Milo's note says: "2 times too wide and 2 times too tall means 2 times too big in area." Which fix makes it right?
A square beside a rectangle drawn 2 times as wide and 2 times as tall, divided into four equal squares. A square beside a rectangle drawn 2 times as wide and 2 times as tall, divided into four equal squares. A square beside a rectangle drawn 2 times as wide and 2 times as tall, divided into four equal squares. - Change it to 4 times, because 2 + 2 = 4
- Leave it at 2 times; it is already right
- Change it to 4 times, because 2 × 2 = 4
- Change it to 8 times, because 2 × 2 × 2 = 8
