Study the survey of India toposheet 45D/10 given and answer the following questions.
(i) Which is the largest settlement? Name and identify it.
Wahan is the largest settlement located at grid reference 1923.
(ii) Identify a steep slope shown on the map and give four figure grid reference of the same.
Grid reference 2314 shows a steep slope.
(iii) In what colour are contour shown on the map? What is meant by Index contours?
Contours are shown with brown colour on the map.
The ordnance survey maps of 1:50,000 scale have contours drawn at the vertical interval of 20 m. Although the contour interval is 20 m, in the topographical maps one finds the heights shown as 100 m. To make the contour maps distinct, every fifth line in multiple of 20 m is accentuated and this is called Index contour.
(iv) Name the settlement patterns shown in the given survey sheet. Why is Anadra an important town?

How do forests help in conserving our wildlife and ecobalance in nature?
Forests are the natural habitat of a large variety of wildlife. Wildlife refers to the animal species that are not domesticated. So, any living organism that lives in the forest region is associated with wildlife. It is found in almost all ecosystems such as rain forests, boreal forests, plains, grasslands, deserts etc. Wildlife provides great stability to our environment wherein they are involved in natural processes either directly or indirectly. Each living organism is placed in the food chain and is equally important, they may be a producer, a consumer or a decomposer, all these are interlinked and depend on each other for their survival. Since, forests provide a habitat to wildlife, they help in conserving our wildlife.
Animals release carbon-dioxide during respiration which is absorbed by plants. On the other hand, plants release oxygen during the process of photosynthesis. In this way the oxygen and carbon dioxide cycle goes on. Since forests contain a large number of plants and trees, they help in maintaining the balance between oxygen and carbon dioxide in the atmosphere.
Forests also affect the climate of a place by regulating the temperature and rainfall of the area. They prevent soil erosion as well. Hence, forests help in balancing our ecosystem.
What is meant by a rain shadow area?

Give reasons for the following:
