Question

Chemical weathering does not include which of the following? abrasion
hydration
oxidation
carbonation

Answer 1

Abrasion is when something is scraping against something and/or wearing out

hydration is when something gets hydrated - absorbs something

oxidation is when something is being oxidized - combining something with oxygen (chemically)

carbonation definition
"Carbonation is the process of dissolving carbon dioxide in liquid. The process usually involves carbon dioxide under high pressure. When the pressure is reduced, the carbon dioxide is released from the solution as small bubbles, which causes the solution to "fizz". This effect is seen in carbonated soft drinks."

Answer 2

So chemical weathering is when something weathers with chemical reaction
meaning that it doesn't just break, it changes the substance
for example, if I was to cut a piece of paper, then it's still the same paper, just in pieces
then if I burned a piece of paper, then it's not paper anymore, it's now ash.
so basically, with chemical weathering it's the same thing.


So find which ever one from the definitions of the words I've gave doesn't match this.
So it has to be a physical change (Like cutting a piece of paper)
So we're not looking for chemical weathering, notice the question says `does not include`
