(1a)To draw the map to a new scale from 1:50,000 to
1:25,000 means to enlarge the map to twice its
i.e old scale/new scale =50,000/25000=2

cultivations for minimal crop production.
(ii)presence of good road networks showing urban

Latitudes are angular distances drawn along the earth
surface dividing the earth north and south of the

of places on the earth
(iii)they both contain great circles.
(3cii)the lines of latitudes are called parallels while
that of longitudes are called meridians.
(3ciii)the lines of latitudes are used for calculating
distance while that of longitudes are used for
calculating local time.
(3civ)the lines of latitudes run from west to east while
that of longitudes run from north to south.
(3cv)the lines of latitude measure up to 180 degree
while that of longitude measure up to 360 degree.

place over a period of time usually measured over a
period of about 35years.
Chemically formed sedimentary rocks are
precipitation from rock solutions.
