How does acid precipitation affect marble and limestone buildings? Acid rain is a type of precipitation that is characterised by containing contaminating substances such as sulphuric and nitric acid‚ both of which have harmful effects on the environment. Both marble and limestone are extremely vulnerable to the damages done by acid rain due to their components. These materials contain calcite‚ a substance that easily reacts and dissolves with acid. Acid rain is the cause of the destruction of many

and put it in their own museum for visitors to see. This document has so much importance to the United State of America and it just would not be right for someone else to be showing it off. This is the issue that has risen with the Elgin Marbles. These marbles hold such a large part of Greek history and art but they are being seen by others in the British Museum. The Greeks have tried for decades to get these important items returned but the British Museum just does not want to let them go.

Freshman Physics Name:_________________________________ Per:____ LAB: Marble Launcher Due Date:_________________ You have learned that the motion of any object moving through the air affected only by gravity is an example of projectile motion. Examples of projectile motion include a basketball thrown toward a hoop‚ a car driven off a cliff by a stunt person‚ and a marble launched from the CPO marble launcher. Toss a ball some distance and you can imagine in your mind the arc it follows

Some avoid marble because they hear it’s hard to keep “looking nice” or they think it’s too expensive. So while it may cost more than some other options you have‚ rest assured your marble floor will long outlive you—if you let it. It does take some care‚ but this can be far outweighed by the sheer elegance it offers. When it’s first installed‚ your marble floor will need a protective sealant. Your natural stone supplier can recommend the best product for the particular marble you’ve selected

PLANNING: Skill Area P Write down the aim of your Investigation. To investigate the effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid. Briefly describe your Preliminary Experiment and include your results. Explain how these results have helped you plan your main experiment (p8b). An increase in concentration will lead to an increase in the rate of reaction because there will be a greater number of particles per unit/cm3. The particles will

symbol of a nation’s power—and who should own it is central to the debate of returning artifacts to their countries of origin. The argument predominantly revolves around the marbles removed from the Parthenon by the British Lord Elgin. While the Greek government does not recognize the British Museum as the owner of the Parthenon Marbles‚ it can be said that they did acquire them by the proper means of the time. Other countries have asked for previously removed artifacts‚ such as the Rosetta Stone and the

The Elgin Marbles / Parthenon Sculptures I read two articles on the internet that provided some very interesting points in regards to the “Elgin Marble” which are better known as the “Parthenon Marbles.” Between 1801 – 1805‚ Thomas Bruce‚ Seventh Lord Elgin‚ procured the marble art and took them to Britain. Lord Elgin’s original intentions were to obtain some sketches and plaster casts made of the great sculptures and reliefs on the Parthenon and other nearby ruins. At the time Greece
