7- Environmental Systems & Ecosystem Ecology (term-definition)

precipitation

• water held underground in the soil or in pores and crevices in rock.
• Any form of water that falls from clouds and reaches Earth's surface.
• Evaporation of water from the leaves of a plant
• process of converting nitrogen gas into nitrogen compounds that plants can absorb and use

positive feedback loop

• the movements of matter within and between ecosystems
• A feedback loop in which a system responds to a change by returning to its original state, or by decreasing the rate at which the change is occurring.
• bacteria that turn nitrogen oxides back into nitrogen gas.
• a feedback loop in which change in a system is amplified

crust

• generation of biomass in an ecosystem
• Earth's outermost layer.
• lack of oxygen
• water that flows over the ground surface rather than soaking into the ground

mantle

• the movement of carbon from the nonliving environment into living things and back
• The layer of hot, solid material between Earth's crust and core.
• water that flows over the ground surface rather than soaking into the ground
• the level below which the ground is saturated with water.

plate tectonics

• Areas where plates move toward each other and collide, causing uplift.
• A theory stating that the earth's surface is broken into plates that move.
• Any form of water that falls from clouds and reaches Earth's surface.
• the movement of carbon from the nonliving environment into living things and back

nitrogen fixation

• the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
• process of converting nitrogen gas into nitrogen compounds that plants can absorb and use
• Areas where plates move away from each other, forming either mid oceanic ridges or rift valleys.
• a type of bacteria that consume nitrogen in the air and change it into a form plants can use

subduction

• generation of biomass in an ecosystem
• One plate going under another plate
• An underground water reservoir.
• Evaporation of water from the leaves of a plant

convergent plate boundaries

• Areas where plates move away from each other, forming either mid oceanic ridges or rift valleys.
• a type of bacteria that consume nitrogen in the air and change it into a form plants can use
• Areas where plates move toward each other and collide, causing uplift.
• Areas where two plates grind past each other resulting in faults such as the San Andreas Fault. Earthquakes often occur at fault lines.

productivity

• One plate going under another plate
• generation of biomass in an ecosystem
• Evaporation of water from the leaves of a plant
• Any form of water that falls from clouds and reaches Earth's surface.

eutrophication

• process of converting nitrogen gas into nitrogen compounds that plants can absorb and use
• the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
• Any form of water that falls from clouds and reaches Earth's surface.
• excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.
