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) The settlement patterns shown in the given survey sheet are-

1. Nucleated settlement
2. Linear settlement
3. Dispersed settlement

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.

A rainshadow area describes the dry area on one side of a mountain or mountain range where less rain falls. This side of the mountain or mountain range is called the leeward side, while the side which has greater rainfall is called the windward side.

In India, rural to urban and urban to rural migration is important because rural to urban population provides labour to the industries in the urban areas. This labour sends remittances to their family in the rural areas and hence help in rural development.

The cold and warm ocean currents affect the climate of a region. The climate of a region becomes cold if a cold current flows near it such as the cold Oyashio current washes the western coast of Japan and makes it extremely cold, whereas if a warm current flows near a region, the winter becomes milder, as is the case with eastern coast of Japan which is washed by the warm Kuroshio current.

The climate of Indonesia is equatorial type because Indonesia lies near the equator and receives a large amount of rainfall due to hot and wet climate.
