NCERT Solutions for Class 7 Geography Social Science Chapter 6 Natural Vegetation and Wildlife

The growth of vegetation relies on temperature, moisture, soil slope, and depth. Natural vegetation is typically categorized as Forests, Grasslands, and Shrubs. Examples of natural vegetation include Tropical Evergreen Forests, Tropical Deciduous Forests, Temperate Evergreen Forests, Temperate Deciduous Forests, Mediterranean Vegetation, Coniferous Forests, and various types of Grasslands. Practicing the NCERT Solutions for Class 7 Geography Chapter 7 is crucial for students aiming to achieve excellent marks in their exams, given its diverse array of questions.

Natural Vegetation and Wildlife

Question 1 :

Answer the following questions.

(i) Which are the two factors on which the growth of vegetation mostly depends?

(ii) Which are the three broad categories of natural vegetation?

(iii) Name the two hardwood trees commonly found in tropical evergreen forest.

(iv) In which part of the world are tropical deciduous forests found?

(v) In which climatic conditions are citrus fruits cultivated?

(vi) Mention the uses of coniferous forest.

(vii) In which part of the world is seasonal grassland found?

 

Answer :

(i) The growth of vegetation depends on two factors: temperature and moisture.

(ii) Natural vegetation is divided into three categories:

  1. Forests – where rainfall and temperature are plentiful for plant growth

  2. Grasslands – plants that grow in regions of moderate rainfall

  3. Shrubs – plants that grow in dry regions

(iii) Two hardwood trees commonly found in tropical evergreen forests are rosewood and mahogany.

(iv)  Tropical deciduous forests, also known as the monsoon forests are found in regions that experience seasonal changes. These areas include India, northern Australia and America.

(v) Citrus fruits are grown in regions marked for hot, dry summers and mild rainy winters. These citrus fruits include oranges, figs, olives and grapes.

(vi) The softwood evergreen trees that grow in the coniferous forests are used for making matchboxes and packing boxes. They are also used for making pulp, which is used to manufacture paper and newsprint.

(vii) Seasonal grasslands can be found in the mid latitudinal zone and in the interior parts of the continent.

(v) Campos

(g) Tropical grassland of Brazil

(vi) Downs

(d) Temperate grassland in Australia


Question 4 :

Give reasons.

(i) The animals in polar region have thick fur and thick skin.

(ii) Tropical deciduous trees shed their leaves in the dry season.

(iii) The type and thickness of vegetation change from place to place.

 

Answer :

(i) Animals in the polar region have thick fur and skin so as to protect themselves from cold climatic conditions. This region has limited natural vegetation due to its cold climate.

(ii) Tropical deciduous forests are found in large parts of India, the northern part of Australia and America. Such areas experience seasonal changes and hence the tropical deciduous trees shed their leaves in the dry season to save water.

(iii) The type and thickness of vegetation change from place to place because of the change in climatic conditions, landform, temperature and moisture. Different types of plants and animals can survive in different types of vegetation.
