Which of these types of weathering requires the presence of water? a. carbonation b. heat effects c. oxidation d. abrasion

The correct answer is A. Carbonation

Explanation:

Weathering occurs as rocks, minerals or similar materials break into smaller parts or disintegrate. Weathering has multiple causes including physical factors such as pressure and chemical factors. In the case of chemical factors, one of these factors is carbonation that occurs as a chemical reaction between water and carbon occurs, and later this reacts with rocks dissolving them.

This process begins when rain or water combines with carbon dioxide forming carbonic acid, later carbonic acid reacts with calcium carbonate of some rocks and minerals, which leads to partial or complete dissolution of the rock (weathering). This process is only possible if there is water because without this the carbonic acid would not form. Therefore, carbonation is the type of weathering that requires water.

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.
