I'll start:
Eutrophication occurs when there is a runoff of excess nutrients such as nitrate or phosphate which leads to algal growth, which blocks out sunlight, killing plants, making the water hypoxic, killing animals and plants, leading to more excess nutrients.

Clean Water Act- aimed to clean our waterways by remediation and stopping point and non point source pollution
Safe Drinking Water Act- developed chemical thresholds for drinking water
What's the difference between point and non point pollution?
Point pollution would be from one point. For example a pipeline disposing of effluents into a river or pollution coming from a single easily identifiable source.
Non point would be pollution from a generally large area. For example a road along a river which has oil run off into the river from cars would be non point since it’s from the entire road and not one single area. Also agricultural runoff from fertilizer is non point pollution because it’s from a vast area.
Okay cool thanks!
Nitrification Fixation: Atmospheric Nitrogen gets converted to nitrite or ammonia. Usually by rhizobium bacteria.
Nitrification: Ammonia or nitrite gets converted to nitrate.
Assimilation: Plants use nitrate
Ammonification: Nitrate goes back to ammonium form.
Denitrification: Goes back to atmospheric Nitrogen.

Tropospheric ozone (down low) is bad because it leads to smog and pollution which harms plants and materials.
Stratospheric ozone (up high) is very good and necessary for deflecting harmful UV rays
Also know the three ingredients for tropospheric ozone: sunlight, NOx (nitrogen oxides), and VOCs (volatile organic compounds).
Ozone - good up high, bad nearby (easy to remember)

What’s the difference between UV rays and UV radiation? Or are they pretty much one on the same?
That’s more in the realm of physics- not relevant to APES, just know that it protects us from harmful UV rays/radiation. Either would be acceptable. Good luck tomorrow.
Thanks!! (:
Acid deposition or acid rain occurs when sulfur dioxide (mainly released from burning coal) reacts with water to produce sulfuric acid. This falls down to earth as acid rain and has a pH of 4.0 (the GPA we most desperately need)
CERCLA is most associated with a superfund for environmental cleanups
The 6 Major Air Pollutants are SPLONC:
S- sulfur dioxide—SO2 P- particulates L- lead—Pb O- ozone—03 N- nitrogen dioxide—NO2 C- carbon monoxide—CO

A trophic cascade is when a predator suppresses it's pray which releases the next lower level from predation Biomaginification is the idea that toxins increase while moving up the trophic level

Volcanoes can happen form at all types of plate boundaries although is by far the most common at divergent and subduction zones. They can also form at hotspots in the middle of plates, creating a line of volcanoes, only the most recent which are active. Island arcs may look similar in that they’re volcanoes in a line, but they are caused by two plates converging and one plate’s material being melted under the other, providing magma for a volcano.
The First Law of Thermodynamics states that energy is neither created nor destroyed, but can only be transferred.
Can anyone please explain the differences between el niño and la niña? I just can’t figure out how to know which one is which.

Thank you! That was really helpful!

You are a nice person!
They literally ask one or more of these on every single FRQ. Just memorize these generic answers and 95% of the time I'd say you'll be set for that question!
If they ask for an ecosystem service: aesthetics, habitat, culture, nutrient cycling, biodiversity
If they ask for a social benefit of an environmental feature: culture, aesthetics, recreation
If they ask for a plan a municipality can enact: public education, new laws
If they ask for an economic benefit of an environmental feature: jobs, tourism
If they ask for a reason why the ecosystem is being disrupted by humans: development, roads, resource extraction
Can you please go into more depth in each of these answers. I have this shit in 9 hours and my dumb ass teacher neither taught us how to do FRQs nor grade any that we did do. I’d really appreciate it, if not it’s cool.
Literally on every FRQ section they ask several of these questions. For example, last year, they asked for an ecosystem service of forests (habitat, biodiversity), economic benefits of dams (jobs), a plan to reduce loss of elephants (new laws/treaties), and why wetlands are being removed (development).
If you memorize thee generic answers, I bet you can get at least 5-12 free points on the FRQ section.
