SUSTAINABLE USE OF FORESTRY Definitions of Forest – Forest is a large area of land covered with trees and plants, usually larger than a wood, or the trees and plants themselves. – Forest is a large area covered chiefly with trees and undergrowth. – Forest is a large tract of land covered with trees and underbrush; woodland. – Forest is a large area dominated by trees. – Forest is a large area where trees grow close together. – Forest is a tract of woodland or wasteland, usually the property of the sovereign, preserved for game. Sustainable use of forest means to maintain and enhance the economic, social and environmental values of all types of forests, for the benefit of present and future generations. Forests and…

TOPIC 1: STRUCTURE OF THE EARTH The Meaning of Earth – Earth is the planet on which we live, the world – Earth is the planet third in order from the sun, having an equatorial diameter of 7926 miles (12,755 km) and a polar diameter of 7900 miles (12,714 km), a mean distance from the sun of 92.9 million miles (149.6 million km), and a period of revolution of 365.26 days, and having one satellite. – The earth is the land surface on which we live and move about. Earth Structure of Earth – The shape of the earth is an oblate spheroid, because it…
WATER MANAGEMENT Definitions of Water – Water is a clear liquid, without colour or taste, that falls from the sky as rain and is necessary for animal and plant life. – Water is a colourless, transparent, odourless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms. – Water is the liquid that descends from the clouds as rain, forms streams, lakes, and seas. – Water is a transparent, odorless, tasteless liquid, a compound of hydrogen and oxygen. – Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth’s hydrosphere and the fluids of most living organisms. Water Definitions of Water Management – Water management is the activity of planning, developing, distributing and optimum use of water resources…
CONTINENTAL DRIFT THEORY History of the Theory Continental drift was first conceived by scholars and philosophers named Francis Bacon, George Buffon, and Alexander von Humboldt. As maps grew more accurate the landmasses began appeared as puzzle pieces. The continents once had fit together but had drifted apart after millions of years. The continents now far apart showed similar sediment, rock formation, and vegetation supporting the theory that they were one landmass in the past. These men helped establish the idea of continental drift, but Alfred Wegener spent much time exploring and researching to prove this theory. Alfred Wegener, in full Alfred Lothar Wegener, (1880…

SPACE DYNAMIC (WEATHER AND CLIMATE) The Meaning of Climate – Climate is the average weather in a given area over a longer period of time, typically averaged over a period of 30 years. Or, – Climate is the average weather conditions of an area observed and recorded over a long period of time (about 30 years) Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, which includes the ocean and ice on Earth. The climate of a location is affected by its latitude, terrain, and altitude, as well as nearby water…

PLATE TECTONIC THEORY History of Plate Tectonics The concept of plate tectonics was formulated in the 1960’s. Plate tectonics is the modern version of continental drift, a theory first proposed by scientist Alfred Wegener in 1912. Wegener didn’t have an explanation for how continents could move around the planet, but researchers do now. Plate tectonics is the theory of geology, said Nicholas van der Elst, a seismologist at Columbia University in New York. The theory also takes the combination of theory of theory of isostacy, continental drift…
SUSTAINABLE MINING Definitions of Mining – Mining is the extraction of valuable minerals or other geological materials from the Earth, – Mining is the industry or activity of removing substances such as coal or metal from the ground by digging: – Mining is the industry and activities connected with getting valuable or useful minerals from the ground, for example coal, diamonds, or gold. – Mining is the process or industry of obtaining coal or other minerals from a mine. Mineral is a valuable or useful chemical substance that is formed naturally in the ground. For example, gold, diamond, coal, copper, oil, salt and gas. Sustainable mining is to maintain and enhance the economic, social and environmental values of all types of minerals, for the benefit of present and future generations. …
