Answer:
The correct answer is option C, cementation and melting
Explanation:
Cementation is the process by which the soil particles stick to each other with the use of clay or any other mineral. The ions carried in the water are basically responsible for the cementation as they lead to precipitation of minerals and its constituents For example – formation of silica, calcite etc. is through cementation.
While the rock at greater depths of ocean or in volcanoes are melted into liquid form due to excessive pressure and heat, which then recrystallizes to form a new rocky composition.
Both cementation and melting thus shape the structure of earth and its constituents
