============================
(4a)
Weathering is the process by which rocks and minerals on the Earth's surface are broken down into smaller particles through physical, chemical, or biological means without any movement or transportation of the material.
(4b)
Exfoliation is a physical weathering process in which layers or sheets of rock peel away from the surface due to pressure release or thermal expansion. This often occurs in regions with significant temperature fluctuations. During the day, rocks expand due to heat, and at night, they contract due to cooling. Over time, this repeated cycle causes the outer layers to weaken and break away, resembling the peeling of an onion
