Answer:
Chemical weathering changes the soil pH and affects the crops that grow on them
Explanation:
Chemical weathering refers to the breaking down of rocks through chemical reactions.
Whenever rocks which are chemically active come in contact with acidic rain, they react to form new compounds. These new compounds formed usually have different properties from their parent rocks.
As a result of chemical weathering, changes in the soil properties can occur such as its pH. These changes will affect the nutrients which can be found in them, thus affecting farming practices on such soil.
Convection. It occurs when a cooler, denser mass of gas or liquid replaces a warmer, less dense mass of gas or liquid by pushing it upward. A good example would be steam rising from a pot of boiling water on a stove top.
When the water is boiled, the water moves in roughly circular patterns because of convection. This motion is due to density differences that result from temperature differences. Also referred as a convection current.
Hope this helps you out.
