Question

according to the rock cycle, which geological processes form sedimentary rocks?
a volcanic activity and lava flow
b melting and solidification
c weathering and erosion
d heat and pressure

Explanation:

Sedimentary rocks are formed from the accumulation and compaction of sediments. Weathering breaks down rocks into smaller particles and erosion transports these sediments. These sediments then settle and are compacted over time to form sedimentary rocks. Volcanic activity and lava flow form igneous rocks. Melting and solidification are processes related to igneous rock - formation. Heat and pressure form metamorphic rocks.

Answer:

C. weathering and erosion
