  • A. Only at the poles
  • B. Yes, they are 360° apart
  • C. No; they identify the same meridian
  • D. Yes, one is in the east and one in the west

Explanation: 180° east and 180° west are the same line.

Correct answer: No; they identify the same meridian
  • A. Yes, always
  • B. Yes, except in the Arctic
  • C. No; it follows the prime meridian instead
  • D. No; it deviates to accommodate countries and island groups

Explanation: The Date Line zigzags around the 180° meridian to keep island nations on one calendar day.

Correct answer: No; it deviates to accommodate countries and island groups
  • A. The Northern and Eastern Hemispheres
  • B. The Southern and Eastern Hemispheres
  • C. The Southern and Western Hemispheres
  • D. The Northern and Western Hemispheres

Explanation: North latitude puts it in the Northern Hemisphere; east longitude puts it in the Eastern Hemisphere.

Correct answer: The Northern and Eastern Hemispheres
  • A. The Southern and Western Hemispheres
  • B. The Northern and Western Hemispheres
  • C. The Northern and Eastern Hemispheres
  • D. The Southern and Eastern Hemispheres

Explanation: South latitude means the Southern Hemisphere; west longitude means the Western Hemisphere.

Correct answer: The Southern and Western Hemispheres
  • A. The Northern and Eastern Hemispheres
  • B. The Northern and Western Hemispheres
  • C. The Southern and Western Hemispheres
  • D. The Southern and Eastern Hemispheres

Explanation: North latitude and west longitude place it in the Northern and Western Hemispheres.

Correct answer: The Northern and Western Hemispheres
  • A. The Southern and Western Hemispheres
  • B. The Northern and Eastern Hemispheres
  • C. The Southern and Eastern Hemispheres
  • D. The Northern and Western Hemispheres

Explanation: South latitude and east longitude place it in the Southern and Eastern Hemispheres.

Correct answer: The Southern and Eastern Hemispheres
  • A. 23.5°
  • B. 24.5°
  • C. 23.3°
  • D. 23.03°

Explanation: Thirty minutes is half a degree, so 23°30′ equals 23.5°.

Correct answer: 23.5°
  • A. 45°25′
  • B. 45°15′
  • C. 45°02′
  • D. 45°52′

Explanation: A quarter of a degree is 15 minutes, so 45.25° equals 45°15′.

Correct answer: 45°15′
  • A. 10°
  • B. 55°
  • C. 15°
  • D. 5°

Explanation: Subtracting 20° from 35° gives a 15° difference.

Correct answer: 15°
  • A. 15°
  • B. 5°
  • C. 25°
  • D. 35°

Explanation: From 20° N down to the Equator is 20°, plus 15° to 15° S, totalling 35°.

Correct answer: 35°
  • A. About 11 kilometres
  • B. About 111 kilometres
  • C. About 1,111 kilometres
  • D. About 1,011 kilometres

Explanation: One degree of latitude corresponds to roughly 111 km on the ground.

Correct answer: About 111 kilometres
  • A. 1,110 kilometres
  • B. 555 kilometres
  • C. 55 kilometres
  • D. 111 kilometres

Explanation: Five degrees of latitude at 111 km each gives 555 km.

Correct answer: 555 kilometres
  • A. No; it is smallest at the Equator and increases towards the poles
  • B. Yes, it is 111 km everywhere
  • C. Yes, except at the poles
  • D. No; it is greatest at the Equator and decreases towards the poles

Explanation: Meridians converge toward the poles, so a degree of longitude shrinks with latitude.

Correct answer: No; it is greatest at the Equator and decreases towards the poles
  • A. 340°
  • B. 180°
  • C. 10°
  • D. 20°

Explanation: The two meridians are 10° on either side of the 180° line, so the smaller gap is 20°.

Correct answer: 20°
  • A. Points where the Equator meets the prime meridian
  • B. The two tropics
  • C. Two points directly opposite each other on Earth, with opposite latitudes and longitudes differing by 180°
  • D. Points on the same meridian at equal latitudes

Explanation: Antipodes are diametrically opposite points on the globe.

Correct answer: Two points directly opposite each other on Earth, with opposite latitudes and longitudes differing by 180°

5776. A lake is:

  • A. An underground water reserve
  • B. A coastal inlet of the ocean
  • C. A flowing channel of water reaching the sea
  • D. An inland body of standing water occupying a basin surrounded by land

Explanation: A lake is still water held in a land-enclosed basin.

  • A. A lake containing water with a low concentration of dissolved salts
  • B. A lake formed by glaciers
  • C. A lake with no outlet to the sea
  • D. A lake used for drinking water only

Explanation: Freshwater lakes have only small amounts of dissolved salts.

Correct answer: A lake containing water with a low concentration of dissolved salts
  • A. A lake fed only by rain
  • B. A lake containing a relatively high concentration of dissolved salts
  • C. A lake with water safe for drinking
  • D. A lake at high altitude

  • A. A lake formed in a volcanic crater
  • B. A lake that freezes every winter
  • C. A lake in a drainage basin with no surface-water outlet to the ocean
