Suppose mechanical weathering breaks a rock into pieces. How would this affect the rate at which the rock weathers chemically? How do chemical and physical weathering differ? Explain your answer in at least 3 sentences.

Explanation:

Mechanical weathering increases the rate of chemical weathering.

As rock breaks into smaller pieces, the surface area of the pieces increases. With more surfaces exposed, there are more surfaces on which chemical weathering can occur.

Chemical weathering is different from mechanical weathering(physical weathering )  because the rock changes, not just in size of pieces, but in composition.

That is, one type of mineral changes into a different mineral.

Chemical weathering works through chemical reactions that cause changes in the minerals.
