Final answer:
In a laboratory, weathering and erosion can be studied through controlled experiments that simulate these processes.
Step-by-step explanation:
In a laboratory, you can study weathering and erosion by creating controlled experiments that simulate these processes.
For example, you can simulate weathering by exposing rocks to different temperatures and moisture levels and observing the effects over time.
Additionally, you can study erosion by using a flume tank to mimic the movement of water and the erosion it causes.
