Two
What is the structure of an atom?
Electron cloud. Protons & Neutrons serving as the nucleus.
Lakes and Ponds can be categorized as having Littoral, Limnetic, and Profundal zones.
Which zone is so deep that sunlight does not reach?
Profundal zones
To estimate the impact of human lifestyles on Earth we can use the IPAT equation
Impact = Population X Affluence X T_______
What does the "T" stand for?
Technology
How to calculate the global population growth rate
[CBR – CDR] ÷ 10 = growth rate in %
Describe the pH scale
0-6 Acidic
7 Neutral
8-14 Basic
What is evapotranspiration?
The combined amount of evaporation and transpiration
Which Terrestrial Biome is cold, treeless, with low-growing vegetation. In winter, the soil is completely frozen?
Tundra

Condensation
Precipitation
Transpiration
Evapotranspiration
Runoff
What are two factors that drive Human Population Growth
Changes in population size
Fertility
Life expectancy
Age structure
Migration
What kind of charge do electrons have?
Negative charge
What is albedo?
The amount of solar energy reflected by a surface back into space
What is the order of the trophic levels from largest amount of energy transfer to the smallest amount of energy transfer?
Producer (autotrophs) → Primary Producer (herbivores) → Secondary Consumers (heterotrophs) → Tertiary Consumers (carnivores)
Name 2 natural and 2 anthropogenic sources of ecosystem disturbances
natural ecosystem disturbances include hurricanes, ice storms, tsunamis, volcanic eruptions, and forest fires.
Anthropogenic ecosystem disturbances include human settlements, agriculture, air and water pollution, and clear-cutting of forests, as well as strip mining.
What is GPP?
Gross primary productivity (GPP): The total amount of solar energy (usually only 1%) that the producers in an ecosystem capture via photosynthesis over a given amount of time.
Having a lot of wealth such as money, goods, or property.
We discussed two layers of the atmosphere: the Stratosphere and the Troposphere. Which one is the Ozone layer in?
The Stratosphere
Resistance vs Resilience
Resistance: A measure of how much a disturbance can affect the flows of energy and matter.
Resilience: The rate at which an ecosystem returns to its original state after a disturbance.
Phase 2 of a demographic transition plot is called Rapid population growth. Why?
because birth rates remain high but death rates decline due to better sanitation, clean drinking water, increased access to food and goods, and access to health care.
What is the equation of Cellular Respiration?
C6H12O6 + 6O2 ----> Energy + 6H2O + 6CO2
Immigration vs Emmigration
Immigration: the movement of people into a country Emigration: the movement of people out of a country.
Is the fertility rate of DEVELOPED countries higher or lower than 2.1?
TFR is typically 2.1 or less
Weather: the short-term conditions of the atmosphere in a local area. These include temperature, humidity, clouds, precipitation, wind speed, and atmospheric pressure.
Climate: The average weather that occurs in a given region over a long period― typically several decades.
What is the Rule of 70
The rule of 70 may be used to approximately calculate the doubling time (DT) in years. DT ≈ 70 ÷ percent annual growth rate
