Weathering breaks rocks into small pieces through various natural processes like abrasion where wind blows sand and rocks against larger rocks wearing them down, or carbonic acid formation when carbon dioxide dissolves in water forming a weak acid. Chemical weathering also changes the outer form and color of rocks through rain, heat, and wind altering their chemical makeup, while physical weathering modifies the rock structure without chemical changes through exfoliation where rocks peel in layers or other non-chemical impacts.

2. Weathering is when nature brakes up little pieces of rock.

3. Abrasion is when the the wind picks up sand and rocks and drives them against the larger rocks and wares them out.

4. Carbonic acid is when a weak acid, H2O, is formed in solution when carbon dioxide is dissolved in water.

5. Chemical weathering is when you have a rock and it sits out in the rain, heat, or wind and the weather changes its form by changing the color of the outer part or the rust.

6. When exfoliation takes place when “a rock peels like onions.”

7. The Horizon is the layers of the soil.

8. The Humus is the decade plant and animal material.

9. The Physical weathering is when the rock changes its form without changing its chemicals.
