Class 6 Geography Chapter 2 Complete Guide Book — Globe and Maps | PunjabTest.com

A globe is a small model of Earth: true in shape and relative size, but small and hard to carry or to show detail. A flat map shows Earth (or part of it) on paper: easy to carry and detail, but shapes or sizes get distorted.

We use globes to understand the whole Earth, and maps for towns, routes and small areas. Neither is perfect — each suits a purpose.

Here is the trade-off in one sentence: a globe is true but clumsy, a map is handy but never fully true. You cannot peel an orange and lay the peel flat without tearing or stretching it, and flattening the round Earth onto paper has the same problem — something always stretches, shrinks or tears. So use each tool for what it is good at: spin a globe when you want the big picture of continents and oceans in their true shapes, and open a map when you need a street, a route or a small area in detail. Asking which one is better in general is the wrong question; the right question is, better for what job?

Physical maps show natural features: mountains (brown), plains (green), rivers and seas (blue). Political maps show boundaries of countries, provinces and cities.

Thematic maps show one theme: rainfall, population, crops, or roads. A weather map is thematic; a road map helps travellers.

Do not start by staring at a map; start by asking what you need from it, because that tells you which kind to pick up. If you want mountains, rivers and plains, take a physical map and read its colours: brown for high land, green for low plains, blue for water. If you want countries, provinces and capitals, take a political map and follow the boundary lines. If you want one single idea — where it rains most, where wheat grows, where roads run — take a thematic map, because it hides everything else and lets that one theme stand out. In a test, the map's title usually gives the kind away, so reading the title first is free marks.

Scale shows the relation between map distance and real distance, e.g. 1 cm : 1 km means 1 cm on the map = 1 km on the ground. Large-scale maps show small areas in detail; small-scale maps show large areas roughly.

Direction: maps usually put north at the top (compass rose / north arrow). Symbols (conventional signs) stand for features: a blue line for a river, a black dot for a town. The key (legend) explains symbols.

Work through a map in this order and you will rarely go wrong. First, the scale: 1 cm : 2 km means every centimetre you measure on paper is really two kilometres on the ground, so a 5 cm stretch is 10 km — just multiply. Second, direction: find the north arrow or compass rose before you decide anything is north, south, east or west, because the top of the page is only north when the map says so. Third, the key: a blue line, a black dot, a tiny triangle — none of these mean anything until the key tells you that the line is a river, the dot is a town and the triangle is a mountain peak. Large-scale maps show a small area in great detail, like your own mohalla; small-scale maps show a whole country roughly, like a map of Pakistan in your book.

Steps: read the title (what the map shows), check the scale, note the direction, use the key for symbols, then find places with the grid (latitudes/longitudes).

Example: on a Pakistan map, find the Indus river (blue line) flowing south to the Arabian Sea, and the Karakoram mountains (brown) in the north.

Reading a map is a recipe, not a talent: follow the steps in order. Step one, read the title, because it tells you what the map is about — a road map, a rainfall map, a map of Pakistan. Step two, check the scale so your distances mean something. Step three, note the direction from the north arrow. Step four, use the key to learn the symbols. Only then, step five, go hunting for places, using the grid of latitudes and longitudes like rows and columns. Try it on a Pakistan map: the blue line running south to the Arabian Sea is the Indus, and the brown shading in the north is the Karakoram and Himalayas. If you skip the title and key, you are guessing; if you follow the steps, you are reading.

Maps guide travel, plan cities, track weather, and help in emergencies (flood maps). Today, digital maps and GPS on phones give live directions.

Even so, reading a paper map matters when phones fail: batteries die, signals vanish, but a paper map still works.

Maps are not just a school subject; they quietly run daily life. A delivery rider follows a digital map, a town planner uses maps to decide where roads and schools go, and during floods, relief teams use flood maps to see which areas are under water and where help must reach first. Phones and GPS have made all this easier, with live directions spoken aloud. But a phone can run out of battery, lose signal in the mountains, or break — and a paper map needs none of those things. That is why learning to read a paper map is not old-fashioned; it is your backup plan, and in an emergency a backup plan is the whole plan.
