Answer:O B. Weak acid breaks down minerals by reacting with them.
Explanation:
Chemical weathering is the process whereby rain water which sometimes can be acidic ( As rain falls down it reacts with CO2 in the atmosphere and form acid rain), This reacts with the minerals contained in rocks, dissolves and degrades them further to form entire new minerals.
An example of a rock that is greatly affected by overexposure of acid rain is limestone containing calcite which easily degrades by acid rain.
Other processes whereby Chemical weathering can occur are through reaction with water and oxygen.
Answer:The only one difference is that ozone is made up of three oxygen atoms, while the stuff we breathe is made up of only two atoms.
Explanation:
The Earth's gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.

Something cut (Paper)
Molded (Bread)
Boiled (Water)
Mixed (Berries and strawberries)
