( The exterior……..) ----------------------------------- tapering? (The sharpened part ….,) ----------------------------------- pointed? ( The sharpened end….) ----------------------------------------- flat? (The back ……)

  18. Complete the description. • The top and the bottom of this case are horizontal. The front, the back and the sides are vertical. There is a handle on the front. The handle is curved. The interior is hollow. • The interior of cigarette is filled with tobacco. The ends are circular. The exterior is white. • The front edge of the blade is thin. The back edge is thick. The blade is wedge shaped. The end of the handle is tapering.

  19. Latitude and Longitude

  20. Latitude and Longitude The position of places on the Earth’s surface are given in latitude and longitude. These are imaginary circles running round the Earth. Lines of latitude run horizontally and are parallel to the Equator. Lines of longitude run vertically. They converge at the North and South poles. What are given in latitude and longitude? Are the latitudes and longitudes real circles on the earth’s surface? Which lines are parallel to equator? Where do the lines of longitude converge(تلاق)? Horizontal lines are called………….. Vertical lines are called………..

  21. Position of Chicago

  22. Latitude and Longitude The position of Chicago is 42 C N and 88 W. This means that it is situated at the point where latitude 42 crosses longitude 88. ‘N’ means north of the Equator. ‘W’ means west of the zero meridian. This is the line of the longitude which passes through Greenwich. To find Chicago we should know…….. The latitude is……… The longitude is……. ‘N’ means…….. ‘W’ means…….. Primary line of longitudes is……… Primary line of latitudes is ………. Which line passes through Greenwich?

  23. Positions are given in degrees

  24. Positions are given in degrees Positions are given in degrees. Imagine a line from centre of the Earth on the Equator and another line from the centre of the Earth to Chicago. The angle between these two lines is 42. Similarly, the angular distance between the zero meridian and Chicago is 88. What is the angle between the line from the centre to equator and the line to Chicago? And what is the angular distance between the zero meridian and Chicago?

  25. The Earth is not at right angles..

  26. The Earth is not at right angles.. The Earth is not at right angles to its path round the Sun. Therefore, the position of the Sun in relation to the Earth’s surface changes during the year. Twice a year on March 21st and September 21st , the Sun is vertically over the Equator. At other times it is vertically over other latitudes between the tropical zones. These lie between the Tropic of Cancer (23 27 N) and the Tropic of Capricorn (23 27 S). the sun is vertically over the Tropic of Cancer on June 21st and vertically over the Tropic of Capricorn on December 21st.
