Chapter # 4 – Introduction to Geography
4.1 Map Reading
4.1.1 Define Map and globe
Map
A map is a drawing or representation of the whole Earth or a part of the Earth’s surface on a flat surface. Maps use symbols, colours, lines, and labels to show features such as countries, cities, rivers, mountains, roads, and boundaries. Maps can show large areas, such as continents and countries, or smaller areas, such as cities and villages.
Examples of Maps
- Political map
- Physical map
- Climate map
- Road map
- Population map
- Weather map
Globe
A globe is a three-dimensional, spherical model of the Earth. It represents the Earth in a shape similar to its actual shape and shows continents, oceans, countries, and important imaginary lines such as the Equator and Prime Meridian. A globe gives a more accurate representation of the Earth’s shape and relative location of places than a flat map.
Difference Between Map and Globe
| Map | Globe |
|---|---|
| A map is a flat representation of the Earth or part of it. | A globe is a spherical model of the Earth. |
| It can show a small or large area in detail. | It shows the whole Earth at once. |
| It is easy to carry and use. | It is usually larger and less convenient to carry. |
| It can show detailed information such as roads and cities. | It mainly shows major geographical features. |
| Shapes and distances may be distorted when representing the Earth. | It represents the Earth’s shape more accurately. |
Why Are Maps and Globes Important?
Understanding Locations
They help us locate countries, cities, oceans, mountains, and other places.
Studying Geography
Maps and globes help us understand the physical and political features of the Earth.
Navigation
Maps are used to find routes and directions, while globes help us understand the relative position of places.
Understanding the Earth
A globe provides a three-dimensional view of the Earth and helps students understand continents, oceans, hemispheres, and important lines of latitude and longitude.
Key Terms
Map: A flat representation of the whole Earth or a part of its surface.
Globe: A spherical model of the Earth.
Symbol: A sign or picture used on a map to represent a particular feature.
Direction: The position of a place in relation to another place, such as north, south, east, or west.
Scale: The relationship between a distance on a map and the actual distance on the Earth’s surface.
Facts to Remember
- A map is a flat representation of the Earth’s surface.
- A globe is a three-dimensional model of the Earth.
- Maps are useful for showing detailed information about specific areas.
- Globes provide a more accurate representation of the Earth’s shape.
- Both maps and globes help us locate and understand places on Earth.
Summary
A map is a flat representation of the whole Earth or a part of it, while a globe is a spherical model of the Earth. Maps are useful for studying specific areas and showing detailed information, whereas globes are useful for understanding the Earth’s overall shape, continents, oceans, and relative locations.
