Igneous rock is broken down by physical and mechanical means. These would include dissolution by naturally occurring acids that are present in the environment, freeze-thaw cycles, abrasion , ablation, exfoliation, and biological causes such as plant root growth.
The process of breaking igneous rocks into smaller pieces is called weathering. This can occur through physical weathering (such as frost wedging or abrasion) or chemical weathering (such as dissolution or hydrolysis).
Igneous rocks are resistant to weathering and erosion because they are formed from cooled magma or lava, which solidifies quickly and has a crystalline structure, making it harder for external forces to break down. Additionally, they generally lack internal pores or weaknesses that would make them more susceptible to weathering. Lastly, the mineral composition of igneous rocks often consists of minerals that are chemically stable and less prone to chemical weathering.
Igneous rocks can transform into sedimentary rocks through weathering and erosion, which breaks down the igneous rock into sediments that are then compacted and cemented together. Igneous rocks can also undergo metamorphism due to heat and pressure, resulting in the formation of metamorphic rocks. Igneous rocks can also melt and be recrystallized to form new igneous rocks through cooling and solidification.
Igneous rocks can become sedimentary rocks through the process of weathering and erosion, which breaks down the igneous rocks into small particles. These particles are then transported and deposited, forming layers of sediment. Over time, the pressure and compaction from the overlying layers can cement the sediment particles together, creating a sedimentary rock.
Magma is molten rock beneath the Earth's surface. When magma cools and solidifies, it forms igneous rocks. The cooling process can occur either slowly beneath the surface (intrusive igneous rocks) or rapidly on the surface (extrusive igneous rocks).

No.
Through the processes of weathering and erosion.
Yes, igneous rocks can be affected by weathering and erosion. Weathering breaks down the rock into smaller pieces, while erosion transports these pieces to new locations. However, due to their high resistance to weathering, igneous rocks are generally more resistant than sedimentary rocks.
No. Calcite is also found in marble, marl, and can occur in small amounts in igneous rocks as a product of chemical weathering.
Igneous rocks change to Metamorphic rocks through heat and pressure. Igneous rocks change to sedimentary rocks through weathering and erosion until the igneous rock is sediments. The sediments then compact to form sedimentary rocks.

Near igneous rocks, you might find other igneous rocks, metamorphic rocks, or sediments that were derived from the erosion and weathering of igneous rocks. Additionally, hot springs, geysers, and volcanic activity may be present in areas with igneous rocks.
Igneous rocks are more resistant to weathering because they are typically made up of minerals that have a higher resistance to chemical weathering processes. Sedimentary rocks are often made up of softer minerals, weaker structures, and already weathered particles, making them more susceptible to erosion and breakdown compared to igneous rocks. Additionally, igneous rocks have a more crystalline structure which is harder and less porous, providing more resistance to weathering agents.
Igneous rocks can be changed to sedimentary rocks outside of igneous intrusions. This is due to silt built up and weathering.
The three types of rocks involved in the rock cycle are igneous rocks, sedimentary rocks, and metamorphic rocks. Igneous rocks form from the solidification of molten magma, sedimentary rocks form from the deposition and lithification of sediments, and metamorphic rocks form from pre-existing rocks that are subjected to high heat and pressure.
Metamorphic rocks are generally more resistant to weathering compared to igneous rocks. This is because metamorphic rocks have undergone changes in their mineral structure and texture due to intense heat and pressure, making them more compact and less porous, which helps them resist weathering processes like erosion and chemical breakdown.
