Water Cycle
Carbon Cycle
Nitrogen Cycle
Phosphorous Cycle
Which process involves plants having water leave via pores and move into the atmosphere, possibly drying them out.
Condensation
Evaporation
Transpiration
Precipitation
Increases in temperature and droughts can lead to increases in WHICH 2 PARTS of the water cycle, which will move water from liquid form and from plants.
Transpiration
Aquafer recharge
Evaporation
Wastewater runoff
(a) rain is caused via pollution of Nitrogen, Sulfur, and other compounds. This impacts both the Nitrogen, Sulfur, and Water cycle on earth.

Nitrogen Cycle
Carbon Cycle
The carbon cycle has many carbon __________, or areas on earth where carbon is stored in many forms, and transfers from one spot to another.
Sinks
Lockers
Closets
Dishwashers
Choose all of the following that are carbon sinks...
Atmosphere
Biosphere
Hydrosphere
Lithosphere & Geosphere (rocks/soils)
The one in your kitchen
One human impact on the carbon cycle is burning of (a) fuels, which releases Carbon gas into the atmosphere that was in the lithosphere (ground/fossils).
Greenhouse (a) , examples being CO2 and methane, trap heat from the sun and slowly raise earth's temperature. These are increased due to human activities.
How does deforestation by humans play a role in the carbon cycle on earth?
Removal of plants increases atmospheric CO2 levels
Removal of plants decreases atmospheric CO2 levels
Increases Greenhouse gas affect in atmosphere
Decrease Greenhouse gas affect in atmosphere
Atmospheric Oxygen Decreases
As plant life decreases from deforestation and fossil fuel burning increases, the CO2 levels in the air will __________, causing the greenhouse effect to increase.
Rise
Fall
Remain Constant
Fluctuate at random
The ______________ effect is when gases such as CO2 and methane will increase earth's temperature overtime. Fossil fuel burning, agricultural practices, waste can lead to this.
Greenhouse
Global Warming

Bacteria
Decomposers
Fungi
Microbes
Look at the phosphorous cycle. What activity here is leading to an increase in algae in the pond/water source?
From the decomposers

When bacteria convert nitrogen into different usable forms, this is called nitrogen...
Conversion
Nitrification
Conversion
Fixation
Humans impact the nitrogen cycle via which of the following (multiple select)
Burning of fossil fuels
Industrial activities
Agricultural waste
Deforestation
Global warming
Select all of the following that are true about the sulfur cycle:
Sulfur contribute to acid rain
Sulfur is added into the atmosphere via volcanos and fossil fuel burning
Bacteria do not play a role in this cycle
Decomposers and Bacteria play a role in the conversion/cycling of sulfur
Fertilizers and runoff from precipitation adds sulfur to water system
(a) = air, while Biosphere = life forms in a system
(a) = earth/soils, Hydrosphere = water and it's system
Choose all of the following definitions which are true:
Evaporation = snow/rain/sleet
Precipitation = snow/rain/sleet
Percolation = ground water movement
Percolation = movement of water in streams/rivers
Condensation = water vapor to liquid/clouds
What happens to the carbon sink of the lithosphere/geosphere when we burn fossil fuels? Where does it convert from and where does it go to?
Draw one human impact we have on the water cycle:
Pick one to draw: 1. Draw how acid rain is formed. 2. Draw how algae/algal blooms form:
Normally (a) gas in the atmosphere can't be used by organisms, unless bacteria fix/convert to ammonia (NH3) and nitrates (NO3), usable forms of Nitrogen
