Question 18.
Janice and James are studying a rock formation near their school. They are specifically looking for the processes of physical weathering.
When examining the rock and the environment for physical weathering, what types of things should they look for?
the formation of clay minerals, leaching, and animal activity in the area
the presence of lichens, various types of crystals, and fossils
the formation of salt crystals, fractures in the rock, and seasonal temperature fluctuations
the presence of different minerals on the surface, various colors, and plant roots

GPT-5 mini
the formation of salt crystals, fractures in the rock, and seasonal temperature fluctuations
These are all physical (mechanical) weathering processes: salt crystal growth and expansion, physical fracturing, and repeated heating/cooling (thermal expansion and freeze–thaw) break rock apart without changing its chemical composition.
