Answer
Yes, we do celebrate Van Mahotsava in our school.

Answer
The sphere where elephants, deer, earthworms, trees and grasses live and grow is known as biosphere.
Important features of this sphere are:
→ The biosphere is the layer of the planet Earth where life exists.
→ Since life exists on the ground, in the air, and in the water, thus, biosphere overlaps all other three spheres.
→ Plants and animals are biotic elements of biosphere while soil, water, air are abiotic elements.
Answer
It takes me around half an hour to reach my school. Had my school been located across the road from my house, I could reach there within four minutes. Due to the long distance between my residence and school, a lot of time gets wasted in commuting which affects my studies hour as well as playing hours negatively.
Time can be converted into space, vice versa is also true, i.e., we can convert space into time.
3. Answer the following questions in about 150 words.
(i) You observe every day in your surroundings that there is variation in natural as well as cultural phenomena. All the trees are not of the same variety. All the birds and animals you see, are different. All these different elements are found on the earth. Can you now argue that geography is the study of “areal differentiation”?

Answer
Geography helps in understanding the reality in totality in its spatial perspective. Geography, thus, not only takes note of the differences in the phenomena from place to place but integrates them holistically which may be different at other places.
(ii) You have already studied geography, history, civics and economics as parts of social studies. Attempt an integration of these disciplines highlighting their interface.
• Geography and History: Geography influences historical events. Spatial distance itself has been a very potent factor to alter the course of history of the world. Spatial depth provided defence to many countries, particularly in the last century. In traditional warfare, countries with large size in area, gain time at the cost of space. Every geographical phenomenon undergoes change through time and can be explained temporally. The changes in landforms, climate, vegetation, economic activities occupations and cultural developments have followed a definite historical course.
• Geography and Civics: The core concern of political science is territory, people and sovereignty while political geography is also interested in the study of the state as a spatial unit as well as people and their political behaviour.
• Geography and Economics: Economics deals with basic attributes of the economy such as production, distribution, exchange and consumption. Each of these attributes also has spatial aspects and here comes the role of economic geography to study the spatial aspects of production, distribution, exchange and consumption.
