An example of chemical weathering is when something likes oil mixes with electricity. It is a different substance because it changes from what it original was. Because it is mixed with other substances the whole thing changes into a brand new thing.

An example of physical weathering in the real world might be like freezing something.

Rain can keep of on beating the rocks on monuments, slowly weathering writing. Frost wedging could effect monuments too. An example of a monument going through weathering is the Statue of Liberty! Also, Monuments could rust. Depends on what they are made of!]]> 2018-05-09 17:53:51 UTC https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/259395404 https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/259396394 Weathering can effect monuments and historical buildings by both chemical and physical weathering. Depending on the material the building/monuments, specific weathering can and can't work. If the material is weak (because it is old) chemical weathering such as acid rain could make details less defined and harder to see so the substance would be smoother and more dull. While things like frost wedging or things hitting the substance (which is classified as physical/mechanical weathering) can also do the same thing but this time the substance is still itself, rather than being changed from the chemical weathering.]]> 2018-05-09 17:56:06 UTC https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/259396394 https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/259715343 Acid rain is a type of chemical weathering, as it wears away buildings and statues. it is formed by polluted water that evaporates and rains down from a cloud. it creates a new substance, and wears away the old one.

Sometimes, a building can be burned down. This is a type of chemical weathering, as it creates another substance, smoke and ash. Often times, buildings that are burtn down are rebuilt. Acid rain chemically weathers down buildings and historic sites. It burn through them, often timescreating new chemicals in the process. Acid rain is created by polluted water that gets evaportated and is rained down, or pollution enters the cloud that has water droplets in it. These buldings can also be physically weathered. If rocks are thrown at it, the building chips a little, but this does not change the substance that  the beuilding is composed of. Frost wedging can physically damage buildings, as it splits the differences between 2 areas. When rainm enters the cracks between a building, and overnight it freezes, it expands, creating a wedge. This keeps happening, while the water keeps melting and freezing. This can casue buldings to break off of other parts of the building.]]> 2018-05-10 17:33:09 UTC https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/259718227 https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/259719757 One example of chemical weathering is mixing a medicine together.

One example are the mountains. They will slowly go away after a long time. Another example is a statue made out of rock.

This is called Frost Wedging. Frost Wedging occurs in the winter time, creating potholes.

Ex. of physical weathering: Waves crashing against a rocky shoreline, therefore slowly breaking away the rocks into smaller pieces, or sediments, of rock. 

Ex. of physical weathering: Plants growing through cracks. Sometimes, plants, or vines, can grow through cracks in almost anything; sidewalks, streets, roads, etc..
Chemical weathering - Chemical weathering is a term used in science that refers to the erosion, or disintegration, of rocks or any kind of mineral.
Example:  Pollutants from factories and vehicles in the air dissolving into the rainwater forming acid rain.

Acid is created from factory's or cars its basically gas that goes up into the air and comes down with rain, Some buildings also seem darker and dirtier and that's because the reaction from acid and calcite in water traps dirt in the building. Acid rain can also leave stains on marble because the acid rolls of the color from a statue and there is no possible way of cleaning it without damaging the marble.

The Botanical Garden weathers away because of the calcite inside of the limestone. The Grant Memorial changed colors, which is different from our observations, because it’s made out of marble. Finally, there’s the Jefferson Memorial, which is made of calcite, so it’s weathering away too.

When water freezes it expands which makes the crack bigger until it makes a pothole. ]]> 2018-06-04 15:50:05 UTC https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/265424862 https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/265427963 The botanic gardens was made out of limestone which is easily dissolved by acid and water. The pieces in the limestone that are a bit stronger stick out more than the limestone which is dissolved.  On our capital acid rain dissolves calcite which is around harder materials which leaves marks. Gypsum is then created by the calcite and acid and the water and it the traps dirt which gives it a moldy color. It also form a crust which then breaks off. At the Grant Memorial the bronze statue turns this greenish blueish color due to the acid rain which then stains the marble and runs down each step. And apparently there’s no way to clean the green blue without damaging the marble. At the Jefferson Memorial the acid rain eats away around the calcite. Whatever the calcite was holding then gets dissolved which makes these big gaps. So basically acid rain dissolves and damages the buildings in Washington D.C.

For example, when acid rain rains on bronze statues, it turns this blue-green color due to the acid rain. It does drip down onto the pedestal/monument/statue and  there is no way to clean the 
blue-green color without damaging the marble. ]]> 2018-06-04 17:33:48 UTC https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/265453776 https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/265458824 b bhbhjbhbhjbhj]]> 2018-06-04 17:52:58 UTC https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/265458824 https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/265459755 An example of physical weathering is frost wedging. Frost wedging is where any water seeps into cracks in a liquid stage, and freezes. When the water freezes, it expands, but since the surrounding material is solid, it cant expand so it breaks.]]> 2018-06-04 17:57:23 UTC https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/265459755 https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/265462175 2018-06-04 18:08:12 UTC https://padlet.com/tinamcpherson333/zciujpvq1xt8/wish/265462175
