Chemical weathering occurs when minerals in rocks are changed chemically. Which of these will most likely change the rate of chemical weathering on a rock?
rainfall and temperature
Is crushing a rock chemical or physical change?
Grinding something is an example of a physical change, because you are not chemically changing what the substance is, you are only changing the form of it. Another example of a physical change is boiling water, because the water is still water, it's just in a gas form instead of liquid.When something is grinded it is a physical change not a chemical change.

If two identical rocks were weathered one mechnically and the other chemically how would the products of weathering for the two rocks differ?
The product of the mechanically weathered rock would be identical to the original rock. The product of the chemically weathered rock would be dissimilar to the original rock.
