The Three R's

An iceberg begins to melt in the ocean after breaking off a glacier causing this change in the surrounding water.
What is... a decrease in salinity?
100
Lack of rainfall and depletion of soil nutrients resulted in this 1930's event.
What is... the Dust Bowl?
100
This resource can be replaced at a rate relative to its rate of use.
What is... a renewable resource?
100
This biome is home to the most bio-diverse population on Earth.
What is... the rainforest?
100
The three R's.
What is... reduce, reuse, recycle?
200
Researchers attribute this as the cause for the 0.8 degree rise in global temperature.
What is... burning fossil fuels?
200
Chemical runoff into a river has the potential to increase the risk of cancer in marine mammals. (True/False)
What is... true?
200
Metals (e.g. gold, silver, aluminum); radioactive elements (e.g. uranium, lithium); and organic materials (e.g. peat, coal) ALL have this in common.
What is... they are mined from the earth?
200
Sweet potatoes grow best in soil with high porosity, which means they are most abundant in this region of North Carolina.
What is... the Coastal Plains?
200
Following the Dust Bowl of the 1930's, this process introduced more sustainable farming practices.
What is... crop rotation?
300
The most abundant greenhouse gas emitted by humans.
What is... carbon dioxide?
300
Farmers often add fertilizer to re-introduce nitrogen into depleted soil. Without proper practices, excess nitrogen will runoff into nearby lakes or streams causing this negative effect.
What is... eutrophication?
300
A way to make reparations for land that has been stripped by mining.
What is... reclamation?
300
The greatest threat to the diversity of ALL species on Earth.
What is... climate change?
300
Reducing food waste will result in less of this gas, which contributes to global warming.
What is... methane?
400
What is... warmer?
400
Increased levels of carbon dioxide and soil erosion would result from lack of sustainability with this trend of human interference.
What is... deforestation?
400
Scientists would conduct investigations on alternative fuel sources for this reason.
What is... confirm the "new" fuel is cleaner than fuel already being used?
400
Name a possible trend that occurred at points 1 & 2 on the graph above.
What is... technological advancements (e.g. medicine/healthcare, farming practices, industry, etc.)?
400
Recycling this renewable resource in our homes will lessen the chance of a long term shortage.
What is... water?
500
Volatile Organic Compounds (VOCs) are released from burning fuel such as gasoline, wood, coal, or natural gas. Ground level ozone, which forms as a result of the chemical reaction between sunlight and VOCs, is most likely to be present in this area.
What is... an urban heat island (a city)?
500
Urban weather stations, which determine mean temperature, have had the validity of their data questioned because they measure this human-produced effect.
What is... a heat island?

According to this graph water storage increased significantly until the late 70's, at which point suitable locations for building hydroelectric dams became scarce. This has resulted in what trend?
What is... fewer new reservoirs (water storage)?

Most of the trash in the United States is currently disposed of in one of three ways:
32.5% is recycled or composted
12.5% is incinerated
55% is put into landfills
The ecological footprint of a town would be decreased MOST by making these changes.
What is... increase recycling while decreasing incineration and use of landfills?
