Finally, one of the most overlooked quarrying was simply Nile Mud, used for pottery making and for making bricks that were used in most common building applications.

2018-5-1The quarrying sector's primary impact on biodiversity is through the removal of surface features during the extraction of minerals. Through this process, habitats can be altered or destroyed. Secondary effects of the quarrying process, such as noise, dust, pollution and waste removal can also impinge on plants and animals.

It measures the intensity of ground motion. This measured intensity will be stronger if the seismograph is close to a blast and lower if the seismograph is far away. In blasting, the unit of measurement we use to describe this motion is peak particle velocity. The Richter Scale reports the power of an earthquake or its magnitude. It's an
