Q111 (CAPF/2024) Geography › World Physical Geography › Rocks and minerals

Which of the following processes is/are part of the Rock Cycle? 1. Lithification 2. Metamorphism 3. Solidification

Result
Your answer: —  Â·  Correct: D
Explanation

The rock cycle is a continuous process where rocks are transformed between igneous, sedimentary, and metamorphic states [1]. Lithification is the specific process of consolidation and compaction of sediments to form sedimentary rocks. Metamorphism involves the recrystallization and reorganization of minerals within a rock due to changes in pressure, volume, and temperature, transforming existing rocks into metamorphic ones [2]. Solidification (or crystallization) is the process by which molten magma or lava cools and hardens to form igneous rocks [3]. All three processes are fundamental drivers of the rock cycle, facilitating the transition of earth materials from one rock type to another [1][3]. For instance, igneous rocks can be broken into fragments to form sedimentary rocks via lithification, or buried and subjected to heat and pressure to undergo metamorphism [1].
