Energy
What form of energy is stored in a stretched rubber band?
Elastic Potential Energy
What do we call a diagram that shows the diet of several different animals?
Food Web
What causes air to move from one place to another, creating wind?
Air is moving from areas of high concentration to low concentration.
Name one renewable resource and one nonrenewable resource.
Coal, oil, natural gas
Wind, solar, hydroelectric
Give one example of how humans can negatively affect biodiversity.
Habitat destruction, pollution, overfishing, introducing invasive species.
Name the law that says energy cannot be created or destroyed, only changed from one form to another.
Law of Conservation of Energy
What is the term for something that can limit a population size?
What kind of heat transfer happens when the Sun warms the ground, and the warm ground warms the air above it? There are two answers.
The Sun is warming the ground through radiation. The air is being warmed through conduction by the ground.
What does "sustainability" mean when talking about natural resources?
It means that you do not over use a resources and continue to use it year after year.
What is an “ecosystem service”? Give one example useful to humans.
Benefits from ecosystems like pollination, clean water, climate regulation. Example: pollination for crops.
Conduction, Convection, and Radiation
A species that is not from that area and is outcompeting a native species.
Explain how ocean currents can affect a region's climate.
Warmer currents can cause the climate to be warmer and more moist. Colder climates can cause the climate to be drier and colder.
Give one example of a developing technology that uses renewable energy.
Example: solar panels, wind turbines, tidal generators.
Describe one strategy to reduce the impact of an invasive species on native populations.
Strategies: physical removal, biological controls, habitat restoration, public education and prevention.
Explain how an object's speed and mass affect its kinetic energy.
It can either increase or decrease how much energy the object has.
Draw or describe a simple 3 level energy pyramid. Label each level of the pyramid correctly.
Answer is a correctly drawn energy pyramid.
Describe how differences in temperature and salinity can cause ocean water to move.
Warm less salty water rises
Cold more salty water sinks
(Convection)
Explain how unequal distribution of Earth’s resources can affect where people live and how they use land.
Resource-rich areas support industries and settlements; lack of resources can limit agriculture, water availability, and economic development.
Explain how greenhouse gases help keep Earth habitable, and name one activity that increases greenhouse gas concentrations.
Greenhouse gases trap heat and keep the planet warm enough for life; burning fossil fuels increases CO2.
A roller coaster car at the top of a hill has mostly _____ energy; at the bottom it has mostly _______ energy. Fill in the blanks. Your answers must be in order.
Potential / Kinetic
The populations in the ecosystem are balanced.
The ecosystem can support high biodiversity.
What measurements would a meteorologist need to collect to predict the weather? Name three.
Temperature, pressure, wind speed/direction, humidity, and precipitation.
Describe one method to evaluate whether a water resource is being used sustainably, including what data you would collect.
Measure water extraction rates, recharge rates, water quality, population demand; compare use vs. replenishment.
What will happen to a pond if fertilizer was spilling into it?
The oxygen levels would drop and algae would start to grow.
