What are 3 examples of physical weathering processes? - VERIFIED ANSWER✅ Root
wedging, crystallization, and frost action (freeze thaw)
What is the scientific method? - VERIFIED ANSWER✅ Observation -> question -> hypothesis
-> testing -> results -> theory
What is a hypothesis vs. a theory? - VERIFIED ANSWER✅ A hypothesis is an educated guess
and a theory is an explanation that has been verified
,What is an open systems? Closed system? - VERIFIED ANSWER✅ Open systems: Exchanges
take place between outside environment and the system
Closed System: No exchanges take place, isolated

ANSWER✅ Positive budget: Inputs > Outputs
Negative Budget: Inputs < Outputs
Equilibrium: Inputs = Outputs

equal, state of rest
Dynamic Equilibrium: New matter entering and exiting at the same time.
What are positive and negative feedbacks? - VERIFIED ANSWER✅ Positive Feedbacks:
Encourage/grow the change
Negative Feedbacks: Reduce/eliminate the change
