Question

(I meant to make this category be science but I accidentally clicked math)

Answer 1

Answer:

The difference between chemical and physical weathering is that physical weathering does not change the molecular structure of the rock.

An example of chemical weathering is limestone where it is dissolved by water and the ions are carried away.

An example of physical weathering is when water freezes inside of cracks in rocks. The water expands which causes the rocks to split apart.

Answer 2

Answer: Physical weathering is when the physical structure of something is broken down..fast moving water is an example of this because it physically changes the structure of rocks over time. Chemical weathering is the erosion of materials from chemical reactions. Chemical weathering occurs more on a molecular level. An example of chemical weathering is when the minerals in rocks are dissolved by water, which creates a new compound

Hope this makes sense and helps!
