Que 2 What important cultural traits do you observe while going to school? Are they all equal or unequal? Should they be included in the study of geography or not? If yes, why?
ANS. We observe important cultural features like settlements, roads, markets, fields, canals, temples, places of worship, etc., while going to school.
These are all unequal.
They should be included in the study of geography. Because in the study area of geography, cultural features are studied in the form of human activities along with the physical environment. All these are an integral part of the subject matter of geography.

Que 3 You must have seen a tennis ball, cricket ball, orange and gourd. Which of these objects has a shape similar to the shape of the Earth? Why did you choose this particular object to describe the shape of the Earth?
ANS. Yes, we have seen tennis ball, cricket ball, orange and gourd etc.
Of these, the shape of an orange is similar to the shape of the earth.
We have chosen the orange to describe the shape of the earth because the orange is also spherical like the earth and is flattened from above and below. The earth is also spherical and is slightly flattened at the poles.

Que 4 Do you organize Van Mahotsav celebrations in your school? Why do we plant so many trees? How do trees maintain ecological balance?
ANS. Yes, we organize Van Mahotsav celebrations in your school during the rainy months.

We plant so many trees so that the tree can absorb CO2 (Carbon Dioxide) from the environment and the amount of oxygen in the atmosphere remains appropriate. Through this process the trees maintain the ecological balance. Along with this process, the trees hold the soil together with the roots and also help in bringing rain by evaporating from the leaves. Trees also provide shelter to many animals and birds.

Que 5 You have seen elephants, deer, earthworms, trees and grass. Where do they live and grow? What is the name given to that circle? Can you describe some of the features of this circle?
ANS. Yes, we have seen elephants, deer, earthworms, trees and grasses etc.
All of them live and grow in the biosphere existing on the earth.
This zone has been named as the biosphere.
Some of the characteristics of biosphere are as follows: -
1. The biosphere is a mixed form of lithosphere, hydrosphere and atmosphere on the earth, that is, in these three circles, wherever life is possible, there is a biosphere.
2. The extent of the biosphere is up to a depth of 9000 meters in the oceans, up to a depth of 300 meters under the land and up to a height of 5000 meters in the atmosphere.
3. The biosphere was first conceptualized about 100 years ago by the Australian geologist Edward Swaes.

Que 6 How long does it take you to go to school from your residence? If the school was across the street from your house, how long would it take you to reach the school? How does the distance between your home and school affect the arrival time? Can you convert time to space or vice versa, place to time?

ANS.
It usually takes half an hour to go from home to school. Had the school been across the street from the house, it would have taken only a few minutes to reach the school.
Other conditions being equal, it takes longer to cover a greater distance. Time cannot be converted into place or space into time.

Que 7 On observing your surroundings, you find that there is a difference in both natural and cultural facts. Not all trees are of the same type. All the animals and birds that you see are different. All these different elements are found on the surface. Can you now argue that geography is the study of regional variation / areal differentiation?

ANS. Yes, on observing our Surrounding, we find that there is a difference in both natural and cultural facts. Not all trees are of the same type. All the animals and birds that we see are different. All these different elements are found on the surface.

This is due to the difference in physical and climatic conditions found on the surface. For example, the trees and fauna of the Himalayas located in the north of India are related to more rainfall and snowfall, while the effect of dry desert climate on the fauna and flora of Rajasthan is clearly visible.

On studying the above facts, we can argue that geography is the study of regional/regional variation.

Que 8 You have already studied geography, history, civics and economics as parts of social studies. Attempt an integration of these disciplines highlighting their interface.
