The correct answer is option 1, which states that hydrolysis is an effective form of chemical decomposition of bedrock in humid tropics because humid tropics experience high temperature and humidity.
Hydrolysis is a chemical process where water molecules break down minerals in rocks, causing them to decompose and break apart. In humid tropics, the combination of high temperature and humidity provides the ideal conditions for hydrolysis to occur.
High temperature increases the rate of chemical reactions, including hydrolysis. The warm climate in humid tropics accelerates the process, making it more efficient in decomposing bedrock.
Humidity, on the other hand, is the amount of moisture in the air. In humid tropics, there is typically a high level of humidity due to the warm and moist climate. The presence of moisture is crucial for hydrolysis to take place as water is one of the main agents involved in the chemical breakdown of minerals in rocks.
Therefore, the combination of high temperature and humidity in humid tropics makes hydrolysis an effective form of chemical decomposition of bedrock.
