It is equal to the difference between the crude birth rate and the crude death rate.

  • This measure of the population change excludes the effects of migration.

  • Sunrise industry is a colloquial term for a burgeoning sector or business in its infancy stage, showing a rapid boom.

In the coastal and dry regions, rows of trees are planted to check the wind movement to protect soil cover, this process is known as :

  • A shelterbelt is defined as a barrier of trees and shrubs that protects wind and storm and decreases erosion.

  • Shelterbelts may be planted for a specific purpose, which determines how many rows of trees are planted, the species planted, and the planting design.


The freshwater is continuously being renewed and recharged through the:

  • The water cycle, also called the hydrologic cycle, involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff.


It is the uppermost layer, Rich in humus & minerals and Consists of Sand, Silt & Clay:


Horizon A or Topsoil: It is also called the humus layer, rich in organic material. This layer consists of decomposed material and organic matter. This is the reason the topsoil has a dark brown colour. The hummus makes the topsoil soft, porous to hold enough air and water.


In the biosphere living beings are interrelated and interdependent for survival. This life-supporting system is known as the:

  • The ecosystem is the set of species in a given area that interact among themselves, through processes such as predation, parasitism, competition and symbiosis, and with their abiotic environment to disintegrate and become part of cycles of energy and nutrients.

  • The ecosystem of the ecosystem, including bacteria, fungi, plants and animals, depends on each other.


A natural area designated to protect the ecological integrity of one or more ecosystems for present and future generations is known as:
