Answer:
Weathering is the breaking down of rocks, soil, and minerals as well .
Explanation:
in the same place, with little or no movement, and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity and then being transported and deposited in other locations.
The trend will be such that the time taken for the cross to disappear will be increasing.
<h3>Rate of reactions</h3>
The rate of reactions is affected by the concentration of reactants. The more concentrated the reactants are, the more the rate of the reaction, and vice versa. This is based on the condition that all other factors are kept constant.
In the illustrated reaction, the volume of sodium thiosulfate decreases downward while the volume of water increases. This means that the sodium thiosulfate gets more diluted as we move downward.
Thus, the reaction rate will keep decreasing. In other words, more time would be needed for the cross to disappear as the concentration of sodium thiosulfate decreases.

The enthalpy of formation has a negative sign, which means that the reaction is exothermic. In other words, when ethanol is formed, heat is released to the surroundings as a by-product. The reaction for the formation of ethanol is written below:
<em>C₂H₄ + H₂O → C₂H₅OH</em>
