Map: Map is an easy source of information
about Earth.
Longitudes (طول بلد):The vertical line from north to south in globe is called
longitudes.
Longitude divides in degrees.
Longitudes degrees are 360. It’s calculated
from Greenwich a city of England.
Pakistan position on map:On the map of world Pakistan is
located at 23.420 to 36.550 north latitudes
and 60.450 to 75.260 east longitude.
Prime meridian
(نصف
النہار اعظم ):The central line is on zero degree and
called prime meridian.
Latitudes (عرض بلد):Parallel lines have been drawn on the globe from east
to west is called latitudes. in number (90
degree northern latitudes and 90 degrees southern latitudes.
Latitudes degrees are 180 in number (90
degree northern latitudes and 90 degrees southern latitudes.
Equator
(خط استوا):It
is 00. The central line between the latitudes lines which
divides the earth in to two equal parts is called equator.
Tropic of
cancer (خط
سرطان):This line is located at 23degree in the north of equator.
Tropic of
Capricorn (خط جدی):This line is located at 23degree in the south of equator.
Arctic line (دایرہ قطب
شمالی):Arctic line is located in the north of equator at 66 degree.
Antarctic Line
(دایرہ
قطب جنوبی):Antarctic line is located in the south of equator at 66 degree.
Torrid Zone(منطقہ
حارہ):The area between 23degree north and 23degree in south on the line equator
is called Torrid Zone.
Northern temperate Zone (منطقہ معتدلہ شمالی):The Area between23degree and 66 degree in north side is called northern
temperate zone.
Southern temperate Zone(منطقہ معتدلہ جنوبی):The area between23degree and 66 degree in south side is called southern
temperate zone.
Northern Frigid Zone (منطقہ باردہ شمالی):The up area from66 degree in north Zone.
Southern Frigid zone (منطقہ باردہ جنوبی ):The down area from66 degree in south Zone.
The
book of map is called Atlas.
There
are main two kinds of maps. 1) Need based map 2) Scale based maps
Need Based map:
These maps are made for specific purpose for example physiographic, weather,
population, earthquakes and floods etc.
Scale based Map: It has also two types. 1) Small scale map 2) Large scale map
Small scale map:In small scale maps a large part of the earth is shown
through a single inch or a centimeter.
Large Scale Map:In the large scale maps comparatively, small part of the
earth is shown through a single inch or centimeter.
Scale:Ratio between distances on the earth and map is called
scale of the map.
Scale types: 1) Statement of scale 2) Linear Scale
Statement of scale:When the scale of a map is
described in words it is called statement of scale. For example 1centimeter is
equal to 10 kilometers. Which mean that one cm on the map shows 10 km of the
ground.
Linear Scale:When the scale of a map is shown through a proper lengthy line, is called
linear scale.
An
imaginary vertical line from north to south on globe is called…….
a) Longitudes
b) Latitudes
c) Equator
d) None of these
The
calendar days of Eastern and Western Hemispheres are separated by
a) Arctic Date Line
b) Antarctic Date Line
c) Latin Date line
d) International Date Line
