What term is used for the imaginary east-west horizontal lines on the earth?

What is the shape of the meridians?

What do the parallels of latitude and meridians of longitude together form on the globe? 

How many parallels are there in the northern hemisphere?

Which circle forms the eastern and western hemispheres?

Which circle appears as a point on the globe?

How many places on the earth may be located on 45°N parallel?

Parallels of latitude lie parallel to the Prime Meridian.

All parallels of latitude converge at the equator.

Parallels and meridians are imaginary lines. 

8° 4' 65'' is a north meridians. 

Meridians are parallel to each other.

Find the correct graticule out of the following.

How will you express the latitude and longitude of the North Pole? 

How much is the angular distance between the Tropic of Cancer and Tropic of Capricorn? 

Using a globe, write down the names of the countries through which the equator passes. 

Write down the main uses of the graticule. 

Complete the following table.

Observe the figure and answer the following questions:

• Which places are shown on the map?
• In which city is the Taj Mahal located?
• In which continent is the Taj Mahal located?
• In which direction is the Taj Mahal located for Graham in St. Petersburg, for Katya in Kimberley, · for Michico in Tokyo and Minakshi in Port Blair?
• Shahid in Agra is specifying the directions in which the others live. How will he express them?
• In what direction will Natalia in Rome and Enrike in Lima say the other child lives? Will their answers be the same?

Observe the globe in your school. Think about the following question and then discuss it.

There are some vertical and horizontal lines on the globe. Which of these lines are more in number? 

Observe the globe in your school. Think about the following question and then discuss it.

What labels do these lines have? What similarities and differences do you see in the labels? 

Observe the globe in your school. Think about the following question and then discuss it.

Will it be possible to actually draw such lines on the earth?

Use the below figure for the following:

• In the upper portion of the circle, at the centre X, draw angles of 20°, V₁ X K₁ and V₂ X K₂; K₁ and K₂ being the points on the circle. Draw an ellipse joining K₁ and K₂.
• In the lower half of the circle, mark angles of 60° and name the points on the circle as P₁ and P₂.
• Draw an ellipse joining P₁ and P₂.

Can you tell?

• Are the distances between K₁ K₂ and P₁ P₂ the same?
• Compare the distances XK₁ and XP₂. Are these distances the same or are they different?
• Now compare the ellipses you have drawn.
• Which is the larger ellipse? Why?

Use the figure to do the following:

Let the line AM be 0°.

• Draw the line MB. Measure the angle it makes with the line AM and write it near B. Note the semicircle that passes through B and joins the North and South Poles. Trace it. 
• Now join MC. Measure LAMC and write it next to C. Draw a semicircle that passes through 'C' and joins the North and South Poles.
• Draw a line that passes through point A at 0°, and joins the North and South Poles.

A game of reading the meridians on the world map is going on. Shaheen and Sanket are asking each-other to locate places on specific meridians and are making notes of the same. Shaheen asks Sanket to locate Wrangel Island on 180° meridian. Sanket could locate the island in the map but both are confused while making a note of it. They are puzzled whether to write 180°E or 180°W? What would be the precise answer? Please help them. Can we use a similar logic with reference to 0° meridian as well? 

How many parallels and meridians can be drawn on a globe at an interval of 10°?
