Hydrolysis is the weathering reaction that occurs when the two surfaces of water and compound meet. It involves the reaction between mineral ions and the ions of water (OH- and H+), and results in the decomposition of the rock surface by forming new compounds. Temperatures usually stay high (above 70) throughout the year. Humid Subtropical climate is known for hot humid summers. During the summer the average temperature is between 70 and 80 degrees.

Hydrolysis as a form of chemical decomposition of bedrock in humid tropics
The correct answer is option 'C' - Both 1 and 2. Let's discuss why hydrolysis is an effective form of chemical decomposition of bedrock in humid tropics:
High temperature and humidity
In humid tropics, the temperature and humidity are generally high. This means that there is plenty of water available in the environment. Water plays a crucial role in hydrolysis, as it is the chemical reaction between water and minerals that breaks down the bedrock. Therefore, the high humidity in the humid tropics provides the ideal conditions for hydrolysis to occur.
Diurnal range in temperature
The diurnal range in temperature refers to the difference between the highest and lowest temperatures that occur in a day. In humid tropics, there is often a high diurnal range in temperature. This means that there are rapid changes in temperature throughout the day. These temperature changes can cause the bedrock to expand and contract, which can lead to the formation of cracks and fissures. Water can then penetrate these cracks and fissures, accelerating the process of hydrolysis.
Conclusion
In conclusion, hydrolysis is an effective form of chemical decomposition of bedrock in humid tropics due to the high temperature and humidity, as well as the high diurnal range in temperature. These factors provide the ideal conditions for water to react with minerals in the bedrock, breaking it down over time.
