100

Rain, snow and hail are all considered this.

Precipitation

100

This process is normally carried out by plants and removes carbon from the atmosphere.

Photosynthesis

100

The process where nitrogen gas is created and released into the atmosphere.

Denitrification

100

This type of energy is characterized by heat transfer.

Thermal energy

100

This system allows BOTH matter and energy to transfer in and out.

Open System

200

Movement of water across the land.

Runoff

200

When plants and animals die, they do this, which reintroduces carbon to the surrounding environment.

Decompose

200

The process where nitrogen gas is returned back to the Earth.

Nitrogen fixation

200

Energy formed from electrons moving.

Electrical energy

200

The global water cycle has a fixed amount of water that does not changed. It would be considered this type of system.

Closed System

300

The movement of water from plants into the atmosphere is call this.

Transpiration

300

Plants and animals do this process naturally, which releases carbon dioxide into the atmosphere.

Cellular Respiration

300

The process where nitrates are created by bacteria for plants to use.

Nitrification

300

Energy from an object in motion.

Mechanical energy

300

A saucepan on a hot stove with the lid on is considered this type of system.

Closed System

400

The process where water enters the ground and becomes stored underground.

Infiltration

400
Because humans burn trees and combust fossil fuels, there is more carbon in this location.

Atmosphere

400

The process where plants take in nitrogen, then animals eat those plants and gain nitrogen.

Assimilation

400

Energy stored in food or fuel.

Chemical energy

400

A sealed vacuum flask does not allow energy nor matter to enter or leave. It is this type of system.

Isolated System

500

The water cycle is controlled by gravity and this.

The sun / solar radiation

500

This process causes carbon to become dissolved into the surface of the ocean.

Diffusion

500

Dead organisms release nitrogen back into the soil when they decompose.

Ammonification

500

Energy that travels in waves at the speed of light.

Electromagnetic / Radiant Energy

500

The ocean receives water from runoff and loses water to evaporation. It would be this type of system.
