Q. Which of the following processes can convert an igneous rock into a sedimentary rock?

1. Weathering and Erosion
2. Melting
3. Heating and Pressure

Select the correct option from the codes given below:
Answer: Only 1
Notes: Weathering and erosion break down igneous rocks into smaller sediments, which are transported, deposited, and compacted to form sedimentary rocks. Melting turns rocks into magma, and heating and pressure form metamorphic rocks. Only weathering and erosion directly lead to the transformation of igneous rocks into sedimentary rocks; the other processes result in different rock types.
