Black vertical and Horizontal lines on the topographical sheets are called eastings and northings respectively.

The following are seen in white colour on the topo map: __________ ____________, rocky land.

In this method scale is given in a fraction or in a ratio form, such as 1:50,000.

It is a feature generally found along the banks of a seasonal river in arid region and formed due to alternating dry and wet seasons. Land is submerged by flood water during wet season, and rapid evaporation due to intense heat in the dry season cause weathering to occur.

It is water which is salty and is unfit for drinking. In dry regions, due to extreme heat, extreme evaporation occurs leaving high mineral content in the water.

______________are marked on the map by a dot accompanied with a number (e.g. .351).

Cartographer is an art and science of drawing maps, diagrams and charts.

_______________ lines are the broken lines running in the direction of contours and are used in addition to contour lines to represent particularly the hilly or mountainous region. They are not as accurate as contours and are based on observation only.
