(2.6.4) Estuaries are marine environments located in areas where fresh water from rivers flow into the ocean. Estuaries are one of the most biologically productive ecosystems. Birds, fish, turtles and many other organisms inhabit these ecosystems. Which will MOST likely cause changes to estuary habitats on a global scale?

(2.4.1) When water is removed from the ground, the soil can become compacted, a process called subsidence. Some parts of Mexico City have subsided by as much as 9 inches per year. This is due to:
Earthquakes
Gopher tunnels
Groundwater depletion
Climate change
Groundwater depletion
300
(2.2.1) Building cities creates “Microclimates” such as:
more stable temperatures year round
Heat islands
Lower than normal temperatures
Moderate temperatures in the spring and fall
Heat islands
300
(2.6.2) When compared to current average conditions, which term would BEST describe conditions in Earth’s lower atmosphere (the troposphere) if the amount of greenhouse gasses decreased?
less dense
cooler

(2.6.2) Raising livestock, (sheep, cattle and pigs), results in the production of methane gas in large amounts. Methane is one of the main greenhouse gasses. As the demand for food from livestock increases; more methane is released into the atmosphere, most likely causing:
an increase in acid rain
a thinning of the ozone layer
a decrease in sea levels
an increase in global temperatures
an increase in global temperatures

(2.4.2) What is an example of point source pollution?
Chemical runoff from roads
Beach trash that gets into the water
Sewage pipes draining into bodies of water
Fertilizer from lawns seeping into groundwater
Sewage pipes draining into bodies of water
