Sustainable Aviation The term ‘Sustainable’ was first introduced in 1972 from United Nations conference on Ecological Sustainable Development‚ whereby the spotlight was focused on reconciliation of environment and economic development. (Sustainable Development‚ 2012). This essay discusses how aviation industries efforts to a sustainable future are mere tokenism. Cited by Daley B. et al‚ ‘Sustainability means balancing economic‚ social and environmental benefits and costs of development‚ both for

1. There are four eras of Earth’s history they are Precambrian (87.6%)‚ Paleozoic (7.1)%‚ Mesozoic (3.9 %)‚ and Cenozoic (1.4 %) 2. There are four layers and two sub layers. * Inner core is solid metal and made up of nickel and iron * Outer core is made of a liquid molten core of nickel and iron * Mantle is made up of dense and mostly solid silicate rock * Lithosphere is the uppermost layer (100km thick) * Asthenosphere is the layer below the

1. Wegner’s hypothesis of continental drift using the observation that the earth’s surfaces are continually changing and other evidence was that the continents had once been joined‚ and over time had drifted apart but he couldn’t explain the mechanism behind it. 2. Evidence gathered by Ewing‚ Tharp and Hess that lead to the theory of plate tectonics was: ⦁ In the early 1950s Ewing‚ with the help of Marie Tharp‚ a cartographer‚ mapped the seafloor using available echo profiles‚ the resulting mapped

GENERAL SCIENCE POINTERS BASIC CONCEPTS AND LAWS Science and Technology Science - is a systematic study that is concerned with facts and principles‚ and methods that could be observed in our natural or physical and social environment. It comes from the Latin word ’scire’ that means ’to know’. - is both a body of knowledge and a process – away of thinking‚ a way of solving problems The Branches of Science THE PHYSICAL SCIENCES • Physics: The study of matter and energy
