2.     23^1/2degree South             Tropic of Capricorn

3.     23^1/2degree North             Tropic of Cancer

4.     0 degree                               Equator

Exercise B(Fill in the blanks)

1.     (b)Equator

2.     (b)South Pole

3.     (a)Tropic of Cancer

4.     (d)Antarctic Circle

5.     (b)Grid

Exercise C(Answer these questions)

Ans: 1. The imaginary lines that run from east to west are called latitudes. These lines are parallel to each other.

The important latitudes are:

a.     Equator(0°)

b.     Tropic of Cancer(23¹/2°N)

c.      Tropic of Capricorn(23¹/2°S)

d.     Arctic Circle(66¹/2°N)

e.     Antarctic Circle(66¹/2°S)

 

 

Ans:2. The important features of latitudes are:    ( page no: 9)

                      

 

 

Ans:3. Longitudes and Latitudes form a network of lines called a grid. It helps us to locate places on a globe.

 

 

Ans:4.  An imaginary line 180° longitude is usually known as International Date Line. It is not a straight line because it passes through many islands in the pacific Ocean.

                                    When we from east to west of the international dateline or the 180 degree meridian we gain a day.  When we move from west to east of the 180 degree longitude, we lose a day.

 

 

Ans: 5. Grid helps us to locate the places on a map. A point at which a latitude and longitude cross each other is the exact location of that place.

 

 

Ans:6.  Difference between Latitudes and Longitudes are-

 

 

Exercise D(Think and Answer)

 

Equator is also known as the Great Circle because it is the longest latitude and it passes through the exact centre of the Earth and divides it in two equal half.

 

Exercise E(Label the important latitude)
