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. …

FORCES THAT AFFECTS THE EARTH Also read: Books of Physical Geography We have two Types of Notes for you: Notes 1 and Notes 2 NOTES 1 Despite our tendency to consider Earth as static, it is actually a dynamic and ever-changing planet. Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of…

POWER ENERGY AND RESOURCES The Meaning of Power and Energy Energy is the capacity for doing work. You must have energy to accomplish work. Power is the rate of doing work or the rate of using energy. Therefore, you need energy to produce power. Without energy there is no power that can be produced. Energy and power are related but totally different concepts. A tank of petrol contains a certain amount of energy. We can combust this petrol in a certain time period, that is, we convert the energy of the petrol into mechanical energy, perhaps to power a car. The power is the energy…
