APES Vocab Quiz Questions with Correct Answers (Grade A+)
Question 1: Active Solar System
Answer: uses electrical or mechanical components to heat water or heat and cool buildings or produce
electricity, pumping heat and absorbing fluid through a collector or glass (Ex: PV Cells)
Question 2: Passive Solar System
Answer: using natural materials or absorptive structures with NO MOVING PARTS to gather and hold heat
(Ex: Greenhouse, Brick + Stone)
Question 3: Biomass
Answer: A measure of the total dry mass of organisms within a particular region, any organic material, does
NOT include fossil fuels b/c it must have recently died
Question 4: Biofuels
Answer: fuel that comes from living matter Fuels, such as ethanol or methanol, that are created from the
fermentation of plants or plant products.
Question 5: Cogeneration
Answer: The use of a single fuel to generate electricity and to produce heat OR the generation of electricity
and other energy jointly, especially the utilization of the steam left over from electricity generation to
produce heat.
Question 6: Concentrating Solar Power System (CSP)
Answer: solar heat used to make electricity, uses mirrors to reflect sunlight on central tube with heat
absorbing fluid that passes thru a heat exchanger where it heats water and makes steam to turn a turbine to
make electricity
Question 7: Power Tower
Answer: A high-temperature concentrating solar power system in which thousands of mirrors arranged in
concentric rings around a tall central tower track the sun and focus light on a heat absorber to generate
steam, which drives an electrical generator.
Question 8: Geothermal Energy
Answer: Energy from steam or hot water produced from hot or molten underground rocks.
