The Water Cycle
What is evaporation?
Somewhere carbon is stored for an extended amount of time.
What is a carbon Sink?
Chemical process by which atmospheric nitrogen is assimilated into organic compounds.
What is fixation?
What is climate?
The burning of carbon emissions.
What is the main source of greenhouse gases?
The evaporation of water from plants occurring at the leaves of a plant.
What is transpiration?
Largest exchange of carbon dioxide between the atmosphere and the ocean surface.
What is dissolving and vaporizing?
Reverse of nitrogen fixation.
What is denitrification?
The burning of fossil fuels causes this effect to occur.
What is the cause of the greenhouse effect?
Corals put under stress die from overheating and do this.
What is coral bleaching?
Water released from the clouds.
What is precipitation?
The burning of coal and other fossil fuels.
What is one of the main causes of carbon emissions in the atmosphere?
Nitrogen converted into ammonia or ammonium by bacteria.
What is ammonification?
The observable increase in global temperatures; considered caused by human-induced greenhouse gases.
What is global warming?
Plastics in the ocean.
What is the main pollutant in the ocean
The flow of water beneath Earth's surface.
What is subsurface flow?
Fresh rock is exposed and weathered faster than older exposed rock.
What is uplifting?
60% of fertilizers don't make it to plants and cause leeching and runoff.
What is the percent of fertilizers that don't make it to plants?
A natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
What are fossil fuels?
What is one of the main threats against all bug life?
The movement of water throughout the Earth.
What is the water cycle?
Long living trees, oceans, plastics.
What are examples of carbon sinks?
Humans contribute twice the terrestrial nitrogen fixation.
What is the amount that humans contribute to nitrogen fixation?
A layer in Earth's stratosphere containing a high amount of ozone.
What is the ozone layer?
The invention of artificial fertilizers in the 1920s led to vast quantities of nitrogen leaking into soil and waterways. In the last 100 years, the amount of man-made nitrogen present in the environment has doubled.
What are the negative effects of fertilizers?
