In order to find out the absolute location of a place on the map, which of the following will be required?
- A.Latitude of the place alone
- B.Longitude of the place alone
- C.Both latitude and longitude of the place
- D.Neither latitude nor longitude of the place
Correct answer
Explanation
The correct answer is C, Both latitude and longitude of the place. The exact, absolute position of any point on Earth is fixed only where its line of latitude crosses its line of longitude.
Latitude measures the angular distance north or south of the Equator, from 0° to 90°, and lines of latitude are called parallels. Longitude measures the angular distance east or west of the Prime Meridian through Greenwich, from 0° to 180°, and its lines are meridians. Together they form a grid of geographic coordinates. New Delhi, for example, lies at about 28.6° N and 77.2° E. Relative location, by contrast, describes a place by its position with respect to other places, such as north of a river or near a city.
A is wrong: a latitude alone gives a whole circle running round the globe, not one point.
B is wrong: a longitude alone gives a half circle from pole to pole, not one point.
D is wrong: without either coordinate only a relative location can be given, never an absolute one.
Exam tip: absolute location = latitude + longitude; parallels run east to west, meridians run from pole to pole.

- A.Brazilian Current
- B.Gulf Stream
- C.North Equatorial Current
- D.California Current

Radiation fog is associated with radiation cooling of the land at night. 3. Advection fog forms when moisture is blown over a cold surface and is chilled by contact. Which of the statements given above are correct ?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
Show answer
All three statements are correct descriptions of fog and its two main types. Fog forms when air near the ground cools to its dew point and its water vapour condenses on tiny dust and smoke particles, so it is in effect a cloud at or near ground level.
