How chemical weathering turns some sandstones into a pile of sand?
For chemical weathering to turn a sandstone into a pile of sand, the sandstone would have to have been cemented by a mineral that was easily attacked by weakly acidic rainfall, most likely calcite. The acidic rainfall would dissolve the cementing material through chemical reaction, leaving the chemically resistant sand grains behind.
Is erosion chemical weathering?
No. Erosion usually involves the transportation of material from one place to another place. Chemical weathering involves the reaction of natural Earth materials with acidic fluids, causing dissolution.
What does chemical and physical weathering have in common?
Physical weathering physically breaks down the rock, whereas chemical weathering breaks down the rock through chemical changes. For example, physical weathering could break down rock through ice wedging, which occurs when water seeps through the cracks in the rock, freezes, and expands, causing the rock to crack. Chemical weathering could be when oxidation (rusting) occurs, when metal is exposed to water and oxygen. Either way they both break down rock.
What is chemical weathering?
Chemical weathering is the phenomenon which contributes to the destroying of rocks with chemical agents; the chemicals may be natural or man made.Examples are water, carbon dioxide, organic acids, acid rains etc.
Is limestone dissolved by carbonic acid a chemical weathering or a mechanical weathering?
This is chemical weathering. Carbonic acid (and often sulphuric acid from SO2) destroy CaCO3 (limestone) through chemical attack.Carbonic acid is formed by reaction of H2O and CO2 to create H2CO3.

Physical or chemical changes that occur in exposed crustal material through the activity of the forces of nature is called?
The process that creates soil from bare rock is called"weathering". The chemical and physical processes of [weathering] transform igneous rock.
Explain different chemical weathering and mechanical weathering?
Chemical weathering rocks may decompose or dissolve and at the same time change in compostion through a certain chemical process to form residuals materials. Mechanical weathering happens when rocks disintegrate or breaks down into smaller pieces through physical forces. (rain, snow, freezing)
Description of physical weathering?
Physical weathering is the process through which rocks are broken down into smaller particles due to physical causes like temperatures and water. The rocks will disintegrate without alteration of the chemical components.
How can a river both cause a chemical and physical weathering?
Water is a major component in weathering process. Its essential for all forms of disintegration either Mechanical/Physical, Biological or Chemical. Water aids in physical weathering through alternating wetting and drying of rocks thereby leading to breaking down of the rock. It helps in chemical weathering through dissolution of chemicals in rocks such as limestone. Water is a cause of both chemical and physical weathering.

What type of weathering is the process that breaks down rock through chemical changes?
Chemical Weathering
Write definiton for physical weathering?
The definition for physical weathering is the break down of rocks through physical, natural means.
Why is the erosion of sandstone a physical change?
The answer is a sandstone cliff that is exposed to the weather goes through physical changes as it gradually erodes in the wwind and rain
