An igneous rock can turn into a sedimentary rock through a process called weathering, erosion, and lithification. Here is the step-by-step process:
1. Weathering: The igneous rock is subjected to weathering, which can involve physical, chemical, or biological processes that break down the rock into smaller fragments or minerals. Physical weathering can occur due to temperature changes, pressure, or the actions of wind and water. Chemical weathering involves the reaction of the rock with water, acids, or other substances. Biological weathering occurs when living organisms, such as plants or animals, break down the rock.
2. Erosion: Once the igneous rock has undergone weathering, the smaller fragments or minerals are transported away from their original location by natural agents such as wind, water, or ice. These agents of erosion can carry the rock fragments over long distances.
3. Deposition: The transported rock fragments, known as sediment, settle and accumulate in a different location, such as a riverbed, lake, or ocean floor. The process of deposition occurs when the transporting agents lose energy and can no longer carry the sediment. The sediment settles out of the transporting medium and comes to rest on the Earth's surface.
4. Compaction: Over time, the accumulated sediment undergoes compaction, which is caused by the weight of the overlying layers of sediment. The weight and pressure exerted on the sediment squeezes out air and water between the particles, causing them to become tightly packed.
5. Cementation: As the sediment continues to be buried, minerals dissolved in groundwater can fill the spaces between the sediment particles, acting as natural cement. This process is called cementation and it binds the sediment particles together, forming a solid rock.
6. Lithification: Finally, through compaction and cementation, the loose sediment transforms into a sedimentary rock. Lithification refers to the processes that convert loose sediment into a solid sedimentary rock, such as sandstone, limestone, or shale.
Through the combined processes of weathering, erosion, deposition, compaction, cementation, and lithification, an igneous rock can be transformed into a sedimentary rock.

An igneous rock can turn into a sedimentary rock through the processes of weathering, erosion, transport, deposition, compaction, and cementation. Heat is not directly involved in this transformation process.
1. Weathering: Physical, chemical, or biological weathering breaks down the igneous rock into smaller fragments or minerals.
2. Erosion: Natural agents like wind, water, or ice transport the weathered rock fragments away from their original location.
3. Transport: The transported rock fragments, known as sediment, are carried by the agents of erosion over long distances.
4. Deposition: The sediment settles and accumulates in a different location, such as a riverbed, lake, or ocean floor.
5. Compaction: Over time, the accumulated sediment undergoes compaction due to the weight of the overlying layers. The sediment becomes tightly packed as air and water are squeezed out.
6. Cementation: Minerals dissolved in groundwater fill the spaces between sediment particles, acting as natural cement. This process binds the sediment particles together, forming a solid rock.
This process does not involve heat directly. However, it should be noted that some sedimentary rocks can later undergo metamorphism (changes in form due to heat and pressure) and become metamorphic rocks, but this is distinct from the process of an igneous rock turning into a sedimentary rock.
