Lecture :1 Geography: Geography is the study of locational and spatial variation in natural and human phenomena on Earth. Vidal de la Blache Geography is the science of places‚ concerned with the qualities of potentialities of countries. The particuler character of a country is expressed by the totally of its feature‚ the social diversities associated with the diversities of places.Geography mainly divided into two parts. • Physical geography • Human geography Physical

atmospheric carbon dioxide by at least 35%. (Boorse‚ 2011). The impact that humans have had on this cycle has change many different elements of the natural environment. An example is the ozone layer is slowly being thinned out‚ which in turn is heating up the atmosphere of the earth. The thinning of the ozone layer is leading to changes with water level. The natural changes to the carbon cycle have been slowed compared to the rate at which humans are adding carbon dioxide to the atmosphere. (unknown)

PROJECT in our physics class to somehow lessen our environmental problem. Our project to be investigated is the HOMEMADEOR NATURAL INSECTICIDE. We all know‚ that our Ozone layer is getting thinner and thinner every time because of the chemicals we use daily. Now‚ to lessen the problem in our ozone layer‚ we are going to study about the use of natural insecticide. We can not only protect and help preserve our environment‚ we can

contains three compositional layers- CORE‚ MENTLE & CRUST. Core: At the centre is the densest of the three layers‚ the core. The core is a spherical mass‚ composed largely on metallic iron‚ with lesser amount of nickel and other elements. Mantle: The thick shell of dense‚ rocky matter that surrounds the core is mantle. The mantle is less dense than the core but denser than the outer most layer‚ the crust. Crust: Above the mantle lies the thinnest and outermost layer‚ the crust‚ which consists

dangerous chemicals that have found their way into the air. Five Sources Cited Pollutants in the air are a serious environmental issue today. We‚ as an industrial society‚ have become far too familiar with terms like smog‚ radon‚ lead‚ asbestos‚ ozone‚ and carbon monoxide. We have also seen on the news‚ read in the newspaper‚ or experienced in our own lives some of the harmful consequences that result from these pollutants -- perhaps as allergies or congestion from exposure to smog or more dangerous

Introduction The major objective of the report is to illustrate the coffee machine environmental life cycle analysis‚ so as to satisfy the increasing demand of the customer for the expectation of the environmental protection as well as to response to the new implemented environmental legislation. As one of the responsible manufacturers located in U.K. specialized in the production of coffee machines dedicated for the public and domestic application‚ the conduction of the environmental life cycle

carbon dioxide (CO2). - Environment was anoxic (no free oxygen) = no ozone layer‚ earth exposed to high solar radiation (UV) - Early Earth = atmosphere of water vapour‚ hydrogen‚ methane and ammonia making production of organic carbon-containing easier. - energy for driving these reactions could have come from a number of sources‚ in particular the sun. Ultraviolet light would easily have reached the Earth’s surface because no ozone layer existed. Other sources include: lightning‚ hot springs and volcanoes

Environmental Science Essay Air Pollution Pollution and How It Affects Elements within an Environment Harry Bond III Everest University The Earth is entirely surrounded by a blanket of air which is called the earth’s atmosphere. The atmosphere allows human‚ plants‚ and all the earth’s creatures big and small to exist. The atmosphere protects the earth and without it the heat from the sun would burn all that is exposed to its rays
