What are Impact and Non-Impact Printers? A printer is an output device that prints characters‚ symbols‚ and perhaps graphics on paper. The printed output is generally referred to as hardcopy because it is in relatively permanent form. Softcopy refers to temporary images such as those displayed on a monitor. Printers are categorized according to whether or not the image produced is formed by physical contact of the print mechanism with the paper. Impact printers have contact; nonimpact printers do

collision.(2) An impact crater is a hole excavated out of a surface usually circular (e.g. a planet‚ moon‚ asteroid‚ or comet) when a smaller mass moving at very high speed collides with it. Impact craters typically have raised rims and floors that are lower in elevation than the surroundings. Meteor crater is perhaps the best-known example of a small impact crater on the Earth. (3) The Barringer crater is over a kilometre in diameter and 750ft in depth.(4) The size and shape of the crater depends on

Meteorites What are impact craters? Impact Craters are depressions on many planetary surfaces. How are craters formed? They are formed by the impact of chunks of interplanetary matter (meteorites) striking the surface. Upon first impact‚ shock waves dissipate the energy of the meteorite through the ground. The ground is compressed rapidly and severely‚ and may be fractured‚ melted or vaporized Next‚ the surface is decompressed‚ and the material is flung violently out from the impact site to form

great wind which looked like an aftereffect of an asteroid strike. The reading points out that an asteroid leaves a huge impact crater which has not been found in Tunguska. The writer also mentions that a large area of forest was damaged which is likely to be a methane explosion. Reversely‚ the lecturer explains that the asteroid exploded in the air so that rocks and impact craters could not be found. Besides that‚ trees below the explosion only missed leaves and branches‚ which is similar to an asteroid

It has been incorporated since into the formal planning and approval processes in several countries‚ in order to categorise and assess how major developments may affect populations‚ groups‚ and settlements.

ENVIRONMENTAL IMPACT ASSESSMENT Environmental Impact Assessment (EIA) is a systematic process to identify‚ predict and evaluate the environmental effects of proposed actions in order to aid decision making regarding the significant environmental consequences of projects‚ developments and programmes. EIA helps the stakeholders with the identification of the environmental‚ social and economic impacts of a proposed development before a decision is taking on whether or not to proceed. Particular
