Comparing a Globe and a Map; Field Visits Class 6 Geography Notes Maharashtra State Board
Friends, we have seen how meridians and parallels are drawn on a globe. We have also learned how they are used to determine the location. In this lesson, let us compare a map and a globe and understand the difference between them.
You must have observed that
- Maps are two dimensional whereas a globe is three dimensional.
- Two-dimensional objects have length and width.
- The product of length and width defines the area.
- Three-dimensional objects have length, width, and height, the product of these provides volume.
- Maps can be used to study the whole world or also regions of a limited extent.
- However small or large the globe, it is only a representative model of the entire earth.
Two-Dimensional – A surface having two dimensions, length, and width, is called two-dimensional, e.g., paper, blackboard, tabletop, land, etc.
Three-Dimensional – An object having three dimensions such as length, width, and height (or thickness) is called three-dimensional, e.g., a duster, box, glass, pot, hill, the moon, etc.
Field Visit (Educational Trip)
A field visit is an important method of studying geography. Field visits help us to understand the geographical and social conditions of a place. Moreover, it provides an opportunity to directly interact with the local people and understand their problems.
With the help of your teacher(s), visit one of the following places to know the geographical condition of the area – a planetarium, post office, bus station, mall, hill, sea coast, small scale industry, etc. Study places like these to observe and record various features.
Your teacher will guide you at the time of the field visit. Prepare a questionnaire with the help of your teacher and take interviews wherever it is necessary. Note down the responses, and make sketches or other notes.
In order to draw a map of the whole world, first a wire globe is prepared. A source of light is placed inside the globe. Then the projection of the wire graticule is obtained on paper. This projection is used to draw maps. Thus, a graticule is essential for drawing the map of the earth or any part of it. That is how a two-dimensional map is obtained on paper from a three-dimensional globe.
Geography Museum
‘EARTHA’ is the largest operational globe in the world. It is housed at Yarmouth in the State of Maine in the United States of America. The rotation and revolution speed of this globe are maintained as per that of the earth.
