Physical weathering breaks rock down into much smaller pieces and gives the original rock a much greater surface area which, when exposed to chemical agents such as carbonic acid, reacts at a much faster rate than it would had the larger rock not undergone physical weathering.

What are the factors that control the rate of chemical weathering and those that control the rate of physical weathering?

Temperature is another significant factor in chemical weathering because it influences the rate at which chemical interactions occur. Chemical reactions rates increase as temperatures increases. With all other factors being equal, the rate of chemical weathering reactions doubles with each 10C increase in temperature.


What do humans do to increase the rate of weathering?

Humans can increase the rate of weathering by activities such as mining, construction, agriculture, and deforestation. These activities expose rocks to the elements, accelerating their breakdown into smaller particles through physical and chemical weathering processes. Industrial pollutants can also contribute to acid rain, which accelerates weathering.


Why does the weathering rate increase at higher elevations?

Weathering rates increase at higher elevations due to factors such as increased physical weathering from freeze-thaw cycles, greater exposure to wind and rain, and more vegetation that can contribute to chemical weathering through root penetration and organic acids. The lower temperatures at higher elevations can also slow down the rate of chemical weathering, leading to the dominance of physical weathering processes.


Does the rate at which a rock undergoes chemical weathering increase or stay the same when the rock becomes more mechanically weathered why?

The rate of chemical weathering generally increases when a rock becomes more mechanically weathered. This is because mechanical weathering creates more surface area on the rock, providing more pathways for chemical reactions to occur. Additionally, cracks and fractures formed during mechanical weathering allow water and air to penetrate deeper into the rock, accelerating chemical weathering processes.


Does the increase of carbon dioxide accelerate or slow down the rate of chemical weathering of the earths surface rocks?

The increase of carbon dioxide accelerates the rate of chemical weathering of the Earth's surface rocks. This is because carbon dioxide dissolved in rainwater forms carbonic acid, which enhances the breakdown of minerals in rocks and speeds up chemical weathering processes.

Does the rate of chemical weathering increase or stay the same when the rocks becomes more mechanically weathered?

The rate of chemical weathering increases when a rock becomes more mechanically weathered, also called abrasion.


What effect would a warmer climate have on the rate of chemical weathering?

A warmer climate would likely increase the rate of chemical weathering because higher temperatures can enhance the reaction rates of minerals with water and acids. This increased chemical weathering could result in faster breakdown of rocks and minerals into smaller particles and release of nutrients into the environment.


Does the increase of carbon dioxide accelerate or slow down the rate of chemical weathering of the earths surface rocks?

The increase of carbon dioxide accelerates the rate of chemical weathering of the Earth's surface rocks. This is because carbon dioxide dissolved in rainwater forms carbonic acid, which enhances the breakdown of minerals in rocks and speeds up chemical weathering processes.


What are two ways that climate can influence weathering rates?

Temperature: Higher temperatures can increase the rate of chemical weathering by speeding up chemical reactions, while lower temperatures can slow down these reactions. Precipitation: Higher levels of precipitation can enhance physical weathering by increasing the frequency of freeze-thaw cycles and providing water to facilitate chemical weathering processes.


Does the rate at which a rock under goes chemical weathering increase or stay the same when the rock becomes more mechanically weather why?

The rate of chemical weathering may increase when a rock becomes more mechanically weathered. This is because mechanical weathering can increase the surface area of the rock, providing more opportunities for chemical reactions to occur between the rock and surrounding substances, speeding up the overall weathering process.


How does an increase in surface area affect the rate of weathering?

If you do a chalk experiment, you will find out that increasing the surface area speeds the rate of weathering. The reaction/weathering will happen quicker. Most people are doing this in science. Your welcome


How are physical and chemical weathering different?

Physical weathering is when some liquid like wind or water over a long period of time breaks of the outer layers of and object, like a rock. Chemical weathering is when an acid or something else chemically eats away at an object like a rock, happening at a much faster rate. Physically weathering - water eroding a rock Chemical weathering - coca cola acids eating away at the rust of a nail. Hopefully this helped


Which would dissolved more quickly chemical or mechanical weathering?

Mechanical weathering typically occurs more quickly than chemical weathering. Mechanical weathering involves the physical breakdown of rocks into smaller pieces, while chemical weathering involves the alteration of rocks through chemical reactions. Factors such as temperature, precipitation, and rock composition can influence the rate of weathering.
