First, boiling is the change of state from a liquid to a gas. Second, boiling of a pure substance occurs at a particular constant temperature called boiling point.
First, the change of state from a gas to a liquid is called condensation. Second, a pure substance condenses at a temperature equal to its boiling point.
Hope this helps you!
Drought and desertification are closely related phenomena. Persisting over months or years, drought can affect large areas and may have serious environmental, social and economic impacts. While drought is a natural phenomenon, whose impacts can be exacerbated by human activities that are not adapted to the local climate, land degradation is the process of turning fertile land into less or non-productive land. In extreme cases in drylands this is called desertification. Land degradation and desertification are complex phenomena driven by un-adapted human activity in combination with land and climatic constraints. Inappropriate land use, such as monocultures, and unsustainable land management practices, such as deforestation, unsuitable agricultural practices and overexploitation of water resources), can cause land degradation that can be further aggravated by drought.
Answer:
Five professional are Cartographer, Town planner, Teachers, Gis experts, Demographers,
Explanation:
- As cartography is the art and science of making maps the Cartographers use geographic data on maps from various maps, diagrams and define locational boundaries. Use the geographic principles of the globe to form models of the earth's surface.
- Town planners or urban geographers use the art of geography to interpret and plan the cities formation and development, they also use the basic geographic techniques like zoning and land-use patterns of a city, the internal structure, etc.
- Teachers, they use their knowledge of geography to teach and develop approaches so as the student can understand the world better, they use innovative ideas and out of text information to spread this body of knowledge far and wide.
- Demographers, generally study the population parameters based on the statistics and data collected from the surveys both primary and secondary. Population studies also come under this field, and analysis the population age and sex ratio, etc.
- Gis experts or professional working with the software need to have a thorough knowledge of geography as it helps them to formalise and plan various types of maps the as they are governed by the government bodies and private groups in the country.
The three transposing agents of erosion are water, wind and deforestation.
