Mining, burning fossil fuels, clearing out land, and use of fertilizers are examples.
What is classified as Human Activity?
The percentage of our atmosphere that is nitrogen gas.
What is 78%?
The step that evaporation follows.
What is condensation?
Plants use CO2 in the process to create sugar and oxygen. (6H2O + 6CO2 -> C6H12O6 + 6O2)
What is photosynthesis?
Phosphorus is not found free in nature but is this.
What is contained mostly in rocks and minerals?
Volcanic eruptions, plate tectonics, and rock forma are examples.
What is classified as Geological?
The groups that cannot directly use nitrogen found in the atmosphere.
What are plants and animals?
The species that is mostly to blame for acid rain.
What are humans?
Animals use oxygen in the process to make more CO2.
What is respiration?
Phosphorus is an essential nutrient for life as it makes up important chemicals such as this.
What is DNA?
What is a nutrient?
Humans add nitrogen by use of this, which can run off into waterways.
What is fertilizer use?
When an acidic chemical (Usually sulfuric) evaporates into the air and joins the water vapor, creating this effect.
What is acid rain?
What is a natural source of CO2?
Some of the phosphorus in soil is washed into this.
What are water basins?
Formation of clouds, lighting, and flow of water are examples.
What is classified as Chemical/Physical?
Anima waste decay, by the bacteria, creates this and this products which are rich in nitrogen and useful for plants.
The effect that acid rain has on animals.
What is making animals sick?
Deposites of carbon, such as past dead and decayed plants and animals, are burned as this. Examples are coal, oil, and natural gas.
What are fossil fuels?
Too much phosphorus in plants can lead to this.
What is plant overgrowth?
Activities done by living organisms.
What is classified as Biological?
Higher organisms use nitrogen to make this for themselves.
What are proteins?
The step that follows condensation.
What is precipitation?
Too much CO2 in the atmosphere may be responsible for this effect.
What is the Greenhouse effect?
This is a man-made source of phosphorus in water
What is pollution?
