1. sustainability - ANSWER ✔ -ability of Earth's various systems, including
human cultural systems and economies, to survive and adapt to changing
environmental conditions indefinitely
2. environmental science - ANSWER ✔ -interdisciplinary study that uses
information from the physical sciences and social sciences to understand
how the earth works, learn how humans interact with the earth, and develop
solutions to environmental problems
3. ecology - ANSWER ✔ -biological science that studies the relations between
living organisms and their environment; study of the structure and functions
of nature.
4. developing countries - ANSWER ✔ -country that has low to moderate
industrialization and low to moderate per capita GDP (gross domestic
product)
-most are located in Africa, Asia, and Latin America
5. developed countries - ANSWER ✔ -country that is highly industrialized and
has a high per capita GDP (gross domestic product)
,6. perpetual resources - ANSWER ✔ -essentially an inexhaustible resource on
a human time scale because it is renewed continuously
-solar energy
7. non-renewable resources - ANSWER ✔ -resources that exists in a fixed
amount (stock) in the earth's crust and has potential for renewal by chemical,
physical, geological processes taking place over hundreds of millions to
billions of years
-copper, aluminum, coal, and oil
-we classify these resources as exhaustible because we are extracting and
using them at a much faster rate than they are formed
8. environmental degradation - ANSWER ✔ -depletion or destruction of a
potentially renewable resource
-soil, grassland, forest or wildlife
-used faster than it is naturally replenished if such use continues the resource
becomes non-renewable (on a human time scale) or nonexistant (extinct)
9. fertilizer - ANSWER ✔ a chemical or natural substance added to soil or land
to increase its fertility
10.What happens to excess fertilizer? - ANSWER ✔ runs into surface water
and groundwater turning into algaeblooms and making groundwater not
usable
11.Effects of frequent irrigation - ANSWER ✔ water tables drop, land can sink,
wells no longer productive
12.pesticide - ANSWER ✔ A chemical intended to kill insects and other
organisms that damage crops.
,13.Purpose of pesticides? - ANSWER ✔ increase crop yields, reduce
competitive environmental effects
14.irrigation - ANSWER ✔ drawing water from the ground, or nearby surface
waters, and distributing it on fields to increase plant growth
15.What is the largest use of freshwater? - ANSWER ✔ irrigation (70%)
16.drip irrigation - ANSWER ✔ MOST EFFICIENT; 95% efficient; most
expensive $$$; holes in hose allow water to slowly drip out; Avoids
waterlogging & conserves waters
17.flood irrigation - ANSWER ✔ flooding an agricultural field with water;
20% of the water is lost to evaporation and runoff; can waterlog soil and
drown plants
18.furrow irrigation - ANSWER ✔ 66% efficient, 33% lost to runoff & evap;
Trench dug along crops & filled with water; easy & inexpensive; water
seeps into soil slowly
19.spray irrigation - ANSWER ✔ More efficient than flood or furrow (less
water loss); ground or surface water pumped into spray nozzles; more
expensive (requires energy for pumps & movement of sprinklers)
20.Earth's lithosphere includes - ANSWER ✔ oceanic and continental crust.
, 21.Seafloor spreading - ANSWER ✔ The formation of new ocean crust as a
result of magma pushing upward and outward from Earth's mantle to the
surface.
22.Divergent plate boundary - ANSWER ✔ The boundary between two oceanic
plates that are moving away from each other to form new ocean crust
23.How is new oceanic crust formed? - ANSWER ✔ 2 oceanic crust moves
away from each other > divergent boundary > zone of divergence >rift
valley >shield volcanoes erupting basalt > new crust
24.Ring of Fire - ANSWER ✔ A major belt of volcanic activity that rims the
Pacific Ocean caused by oceanic - continental plates at convergent boundary
overlapping
25.Convergent plate boundary - ANSWER ✔ A tectonic plate boundary where
two plates collide, come together, or crash into each other.
26.Continental-oceanic convergent plate - ANSWER ✔ Subduction occurs here
when oceanic and the continental plates collide and the oceanic plate bends
and slides into the mantle
27.continental-continental convergent boundary - ANSWER ✔ when two
continental plates collide, mountain ranges are created as the colliding crust
is compressed and pushed upward (ex: the Himalayas)
28.Transform plate boundary - ANSWER ✔ Boundary between two plates that
are sliding past each other.
