Rain, snow and hail are all considered this.
Precipitation
This process is normally carried out by plants and removes carbon from the atmosphere.
Photosynthesis
The process where nitrogen gas is created and released into the atmosphere.
Denitrification
This type of energy is characterized by heat transfer.
Thermal energy
This system allows BOTH matter and energy to transfer in and out.
Open System
Movement of water across the land.
Runoff
When plants and animals die, they do this, which reintroduces carbon to the surrounding environment.
Decompose
The process where nitrogen gas is returned back to the Earth.
Nitrogen fixation
Energy formed from electrons moving.
Electrical energy
The global water cycle has a fixed amount of water that does not changed. It would be considered this type of system.
Closed System
The movement of water from plants into the atmosphere is call this.
Transpiration
Plants and animals do this process naturally, which releases carbon dioxide into the atmosphere.
Cellular Respiration
The process where nitrates are created by bacteria for plants to use.
Nitrification
Energy from an object in motion.
Mechanical energy
A saucepan on a hot stove with the lid on is considered this type of system.
Closed System
The process where water enters the ground and becomes stored underground.
Infiltration
Atmosphere
The process where plants take in nitrogen, then animals eat those plants and gain nitrogen.
Assimilation
Energy stored in food or fuel.
Chemical energy
A sealed vacuum flask does not allow energy nor matter to enter or leave. It is this type of system.
Isolated System
The water cycle is controlled by gravity and this.
The sun / solar radiation
This process causes carbon to become dissolved into the surface of the ocean.
Diffusion
Dead organisms release nitrogen back into the soil when they decompose.
Ammonification
Energy that travels in waves at the speed of light.
Electromagnetic / Radiant Energy
The ocean receives water from runoff and loses water to evaporation. It would be this type of system.
Open System
