What is ecology?
What is the study of how organisms interact with one another and with their nonliving environment.
100
What are the three major tectonic plate movements?
diverging plates converging plates transform faults
100
What is the lithosphere?
Outer shell of the earth, composed of the crust and the rigid, outermost part of the mantle outside the asthenosphere; material found in earth's plates.
100
Prior to mine reclamation laws, mine drainage and acidic runoff from coal tailings were toxic byproducts of... (A) tillage (B) urban development (C) underground mining (D) strip mining (E) industrial processing
(D) strip mining
200
What does "HIPPO" stand for AND what does it describe?
H for habitat destruction and degradation I for invasive species P for pollution P for human population growth O for overexploitation HIPPO describes the five major causes of species decline and premature extinction
200
Why do tectonic plates move?
Convection cells in the mantle move large volumes of rock and heat in loops.
200
What is high grade ore?
Ore that contains a fairly large amount of the desired mineral.
200
Some analysts believe that even in supplies of key minerals become too expensive or scarce from unsustainable use, human ingenuity will find (A) new technologies for mining and extraction. (B) better methods of recycling minerals. (C) substitutes for scarce minerals. (D) new deposits of scarce minerals.
(C) substitutes for scarce minerals.
300
What does NPP stand for AND what does it tell us?
Net Primary Production tell us how much energy is available to consumers.
300
What is biological weathering AND give an example.
Biological Weathering is the conversion of rock and minerals into smaller pieces by LIVING THINGS. Examples: tree roots growing into and rubbing against rocks break them down, lichens release acids that chemically weather the rocks
300
What is a detritivore?
Consumer organism that feeds on detritus, parts of dead organisms, and cast-off fragments and wastes of living organisms. The two principal types are detritus feeders and decomposers.
300
A sedimentary rock containing solid organic matter is called (A) tephra (B) kerogen (C) granite (D) igneous rock (E) gneiss
(B) kerogen
400
What is the difference between aerobic and anaerobic respiration?
Aerobic Respiration: organisms get energy by using oxygen (opposite process of photosynthesis. Anaerobic Respiration (fermentation): Decomposers get energy in the absence of oxygen.
400
What are the two most widely used NONMETALLIC minerals?
sand and gravel
400
What is humus? (Not the dip you eat with pita chips!)
Slightly soluble residue of undigested or partially decomposed organic material in topsoil.
400
Phytoplankton in an open water ecosystem are (A) secondary consumers . (B) primary consumers. (C) producers. (D) tertiary consumers.
(C) producers.
500
What are 3 ways humans alter the water cycle?
Withdrawing large amounts of freshwater. Clearing vegetation and eroding soils. Polluting surface and underground water. Contributing to climate change.
500
Describe the rock cycle. (How does each kind of rock transform into the others?)
Metamorphic---> Igneous by melting and cooling Igneous and Metamorphic---> Sedimentary by weathering, erosion, transportation, and deposition Sedimentary and Igneous--->Metamorphic by heat and pressure
500
What is functional diversity?
Biological and chemical processes or functions such as energy flow and matter cycling needed for the survival of species and biological communities.
500
Biotic and abiotic factors greatly affect (A) population density (B) niche development (C) fecundity (D) education levels (E) genetic drift
(A) population density
