What would happen to the oral cavity if the pH of saliva is acidic?
If the pH of the saliva is acidic it demineralizes (break down) the tooth enamel. When this happens, it causes a thinning of the enamel exposing the dentin, bone-like containing microscopic tubules that lead right to the pulp where the nerves are. If the tooth enamel is eroded, consuming hot, cold, or sugary drinks can become quite painful. Symptoms of acidic or unbalanced saliva pH levels are: bad breath, sensitivity to hot and cold, and cavities
What is the difference between mechanical and chemical process?
I don't think so, mechanical change is when you use something to change the appearance of the object (your Jaw and food for example). Physical change can be caused bye a chemical substance and by and object ( mechanical change ) You welcome :)
Caverns form when rocks such as limestone are dissolved by a mixture of water and?
Limestone is made mostly of calcium carbonate and calcium sulfate. Limestone is eroded by water as the calcium carbonate and calcium sulfate of the stone disolves into running water. Also a factor: other things dissolved in the water. Carbon Dioxide disassociates in water becoming carbonic acid. This means that the more Carbon Dioxide in the water, the more acidic it is. The more acidic the water, the faster erosion can occur. When acidic ground water packed with lots of carbon dioxide is saturated with minerals - dissolved limestone - and that water enters an air filled chamber, the amount of mineral it can hold can suddenly change. This causes excess mineral to come out of solution as the water drips off the ceiling and onto the floor below into structures called Speleothem. .Think rock Icicle.
Deposition is part of the process of?
When a rock is eroded the particles have to go somewhere. After they are moved (by wind, water, etc.) they will eventually be deposited. These deposited particles are then subject to being eroded again.
How do people find coal?
Coal can be found on the surface in areas in which the overlying strata have eroded. Coal layers can be exposed in road cuts and on the walls of river valleys. Coal can also be discovered by drilling core samples down from the surface.
How is rock weathered and eroded?
By Chemical weathering
Is Rocks are eroded to fine sand a chemical or physical change?
Physical
How do you clean eroded metal?
We can use: - mechanical polishing - chemical polishing
Can polluted air break down rocks?
Human pollution is generally acidic. Sometimes, the pollution can contaminate rainclouds or other sources of water, forming an acidic liquid. If a rock has contact with this substance, it could be eroded chemically.
Is a rock being eroded by the wind a physical change?
Yes, a rock being eroded by wind is just being broken down into smaller pieces. The chemical constituents of the rock remain the same.
What do mechanical and chemical weathering have in common?
What mechanical and chemical weathering have in common is they both break rocks down into smaller and smaller pieces. Eventually the weathered rock will be eroded.
Main tips of sedimentray rocks are?
Clastic--formed from eroded rock particles Chemical--formed from the precipitation of chemically saturated solutions.
What is the difference between clastic and chemical rocks?
Clastic: These rocks are composed predominantly of broken pieces of older weathered and eroded rocks Non-clastic/ Organic: A sedimentary rock composed of the remains of plants and animals.
How do you care for enamel?
Avoid acidic drinks, foods ( such as lemons). This erodes the enamel and enamel cannot be replaced once it is eroded. Also, Bulemics and Anorexics damage enamel due to the vomiting they do regularly.
Is shale formed by physical or chemical weathering?
Shale is a clastic sedimentary rock formed of clay and silt sized eroded particles that are a result of both physical and chemical weathering. The clay minerals, however are the result of chemical weathering of feldspars.
How do rocks become sedimentary?
When sedimentary rock is weathered in nature by chemical or mechanical means, the particles that are produced can be eroded and deposited, becoming sediments.
How do sediments become sedimentary rocks?
When sedimentary rock is weathered in nature by chemical or mechanical means, the particles that are produced can be eroded and deposited, becoming sediments.
