Which are examples of chemical weathering ? Choose the two correct answers.

Question

oxidation of certain metals in rock
acid rain breaking down compounds in rock statues
rock breaking apart during a rock slide
an insect digging a hole in rock for its home
an increase in temperature in daytime causing a rock to crack

Answer 1

The two correct examples of chemical weathering are:

1. Oxidation of certain metals in rock - This process involves the chemical reaction of oxygen with metals in rocks, leading to changes in the mineral composition.

2. Acid rain breaking down compounds in rock statues - Acid rain can chemically react with minerals in rocks, causing them to break down and weaken.

The other options you provided are examples of physical weathering or biological activity, not chemical weathering.
