How Does Carbonation Affect The Rate Of Chemical Weathering

Carbonation is another type of chemical weathering. Carbonation is the mixing of water with carbon dioxide to make carbonic acid. This type of weathering is important in the formation of caves. Dissolved carbon dioxide in rainwater or in moist air forms carbonic acid, and this acid reacts with minerals in rocks. chemical weathering tends to be different sorts of chemicals mixed together to form a material. Rust is a good example of what chemical weathering can do.

With an increase in temperature, chemical reactions occur more quickly. Smaller rocks have a larger surface area to volume ratio than larger rocks. This means that a larger proportion of the rock is exposed to the forces of weathering. As surface area increases, so does the rate of chemical weathering. these may be some …show more content…
However, the rates of mechanical weathering will be greater on the Siberian steppes due to freezing and thawing ice. my believed reasoning are these.

Elevation is also a huge factor in weathering. The higher the elevation, you're going to get more rain, water, ice, and wind. And all of those can lead to mechanical weathering, so the higher the elevation, the faster the weathering will happen. So just to review our objectives, we talked about how the composition of rock can affect the rate of weathering.

The more surface area available to be worn away, the faster it's going to weather. So if you have the same amount of rock and one solid rock, that's going to weather slower than if you have the same amount with lots of little tiny rocks, it has more surface area, so it's going to weather quicker. The more surface area exposed, the faster it's going to be worn away.

With a hundred chunks of 5 kg granite they each have a separate weathering process. One block of 100 kg takes much longer because the "weathering" is trying to break down a piece of granite weighing 100
