Identify and briefly define the specific chemical weathering process where minerals such as feldspar react with acidic water to produce clay minerals.

Describe the physical process of pressure release (dilatation) and state one landform typically associated with it.

Evaluate the role of rock structure, specifically the presence of joints and bedding planes, in determining the effectiveness of carbonation in limestone landscapes.

(a) Identify the physical weathering process that occurs specifically in environments where temperatures frequently fluctuate around \(0^{\circ}C\).
(b) Outline two ways in which vegetation can contribute to the weathering of rocks.

(a) Compare the processes of hydrolysis and carbonation in the chemical weathering of rocks.
(b) Briefly explain how rock structure, such as the presence of joints and bedding planes, influences the rate of chemical weathering.
