Glacial systems

Systems:

Inputs:                

• Snow- precipitation         
• Avalanches
• Debris                     

Outputs:

• Meltwater 
• Water
• Sublimation
• Evaporation 
• Debris

Store: 

• Glacial ice
• Ice sheet 
• Lakes/rivers 
• Derbis

Processes 

• Evaporation 
• ABrasion 
• Ice transport 
• Compression 

System= is a set of interralated 'objects' that are connected and that work together to for something

Open system= where the systems receive inputs and transfer outputs of energy and/or matter across the boundaries between them. Most natural systems are open ones.

Closed system= There is transfer of energy, but not matter, between the system and its surroundings. 

Isolated system= a system that has no interactions beyond its boundary layer. Many controlled laboratory experiments are this type of system.
