A) wind erosion
B) chemical weathering
physical-weathering
D) deposition and compaction
Answers
Answer:Its C
Explanation: i took the test trust me
physical-weathering is likely the cause of the underground cave system.
Rocks, minerals, and soils disintegrate through a process known as physical weathering, sometimes known as mechanical weathering.
Abrasion is the main physical weathering process (the process by which clasts and other particles are reduced in size). Temperature, pressure, frost, root movement, and burrowing animals can all cause physical weathering.
For instance, physical weathering will expose more surface area through the use of cracks, speeding up the pace of deterioration.
