Advantages: On the globe, countries, continents and oceans are shown in their correct size.
Disadvantages: Globes may be of varying size and type - big ones, which cannot be carried easily.

Latitudes and longitudes are expressed in degrees. However, the increments of less than one degree can be expressed as a decimal or minutes and seconds. There are 60 minutes in a degree and 60 seconds in a minute. Longitudes can be written with an E or W for East or West and respectively latitudes have N or S for North or South.

Latitudes and longitudes can locate the exact location of a place, but they are not uniform units of measurement.
(i) If we look at the globe, we will see that longitudes are closer together as we move towards north and south of the Equator.
(ii) Only near the Equator, the distance represented by 1° longitude is equal to the distance represented by 1° latitude

The mid-day sun never shines overhead on any latitude beyond the Tropics. The angle of the sun's rays goes on decreasing towards the poles. As a result, the places between the Tropics and the Arctic and Antarctic Circles have moderate temperature.

The Earth is spherical in shape and thus, it is impossible to locate the places on the Earth. To locate a place on the globe, latitudes and longitudes are drawn. The latitudes and longitudes point out the exact positions of places on the Earth's surface.

Slowly rotate the globe on N-S axis and mark a series of points near the middle of the globe from West to East. Join these points and a big circle around the globe is formed. This circle is the largest possible circle that can be drawn on the Earth. It is known as the Equator

The two imaginary lines drawn on the surface of the Earth are :
(i) The lines on the axis, which form the North and South poles.
(ii) The Equator, which runs midway between the North arid South Poles

Greenwich time is called Greenwich Mean Time because GMT is the local time of the old Greenwich observatory i.e., 0°.It is adopted uniformly by all the countries at the international level.

Temperate Zones experience moderate temperature because here the rays of the Sun always fall slanted at these plots which diminishes the heat.

The zone lying between the Tropic of Capricorn and Tropic of Cancer is known as the Torrid Zone. It is also known as hot zone because the mid-day Sun is exactly overhead at least once a year on the latitudes between the Tropic of Cancer and Tropic of Capricorn.

Importance of latitudes:
(i) They help us to locate the position of a place away from the Equator.
(ii) They help us to know the temperature of a place.

Besides the equator at 0°, North pole at 90° Nand South pole at 90° S, the important parallels latitudes are as given below:
(i) Tropic of Cancer at 231/2^o N
(ii) Tropic of Capricorn at 231/2^o S
(iii) Arctic Circle at 661/2^o N
(iv) Antarctic Circle at 661/2^o N
