Water Cycle
Name three important needs for water?
drink, to plants, and to bath
How does carbon enter the geosphere from the biosphere?
Live organism die and decay/decompose into ground or waste from live organisms decomposes into ground
Carbon is a gas that absorbs and re-radiates thermal energy. What type of gas is this?
Greenhouse Gas
Why is phosphorus an important biological molecule?
makes up ATP (energy) and DNA (growth)
When the earth's temperature gradually rises because the amount of Carbon and other greenhouse gasses in the atmosphere increases.
Global Warming
How does water get back to the Earth?
Precipitation
What function do plants have the carbon cycle?
Plants go through photosynthesis and remove carbon from the atmosphere
Why is Carbon essential to life?
It is the building block of all living things
How do plants get phosphorous?
absorb through roots from the soil
If excess Phosphorous cause algea bloom, how do fish die?
Lack of oxygen, suffocation
How does water get from ocean to atmosphere?
Evaporation
How is carbon dioxide returned to the atmosphere from the biosphere?
Respiration (breathing out CO2)
Which carbon reservoir contains the most Carbon?
geosphere (fossil fuels)
What are some items that contain phosphates that can be washed into the ocean?
Fertilizers and pesticides
What are 3 things you could do to prevent excess carbon getting into atmosphere?
Reduce, reuse, recycle; use alternate energy sources to decrease amount of fossil fuels burned; plant a tree
What are human impacts on the water cycle?
Usage of water in their community, pollution
What are the human impacts on the carbon cycle?
Burning fossil fuels, deforestation
Why does deforestation effect the Carbon cycle?
Plants and trees are not there to absorb Carbon during photosynthesis which increase Carbon amount in atmosphere
What happens when too much phosphorus are carried by runoff to oceans?
Algea Bloom
How does deforestation effect the Phosphorous cycle?
Cutting down large amounts of trees ruins soil by eliminating the roots that are holding the soil intact, the phosphorous can easily be washed into bodies of water
How water travels from land to enter the ocean?
Weathering, erosion, runoff
How does carbon get into the oceans?
By diffusion or dissolving when waves are churning
How does Carbon enter the atmosphere from the geosphere naturally?
volcanic eruption
Which earth system does not contain Phosphorous?
Atmosphere
